“You're not supposed to be in here! You're going to ruin the surprise!”The following section contains spoilers.
The Grineer () are the first enemies encountered by newly reawakened Tenno. The expansion of their militaristic, violent Empire across the Origin System through the raiding or conquest of peaceful colonies serves as the primary motivator of the Lotus' call to her slumbering warriors.
As the products of ancient, half-remembered Orokin technology, Grineer are produced rather than born, and in industrial quantities along with their weapons and equipment. Each one is genetically defective to some degree, their genome both originally stunted by their creators, and further damaged by the invasive cloning procedures they themselves have been using to birth each generation in the centuries after the fall of the Orokin. As a result, they have a life cycle that is limited to only a fraction of a normal human lifespan and are prone to a host of degenerative disorders such as decaying limbs and skin or reduced intelligence. They compensate for this by the widespread use of crude cybernetic prosthetics and robust augmentations. Indeed, it could be argued that the Grineer are better at fixing broken bodies than they are at creating ones that function to begin with. Most of their equipment, weapons, and armor are technologically crude but undeniably effective, and many Tenno have fallen because they underestimated the firepower of Grineer machines.
The Grineer were once a caste of genetically modified, purpose-bred clones of the Orokin Empire. Programmed to obey their masters, Grineer slaves were tasked to perform manual labor, gathering resources for the advancement of the Empire.
During The Old War, the Orokin were desperate to defeat their Sentient assailants, so a new breed of Grineer was created from the genes of an individual who had managed to defeat one. These militarized Grineer would be deployed in the Orokin's war efforts but proved futile to the Sentient faction's strategies and defenses.
Eventually, the Warframes were created and led the Orokin to victory, only to be betrayed by the Tenno that controlled these war-suits. After the collapse of the Orokin Empire, Grineer started to congregate to take over territory and technology once belonged to the Empire. At some point in time, the Grineer encountered Orokin twins that helped them fight against remnant Orokin in the Origin System who wanted to restore the Empire. In awe of their close kinship, the Grineer adopted them to be their queens, believing that they attained "Something more than a whole / A true understanding / Of each other soul", a quality that they aspire for.
Their nominal "homeworld" is a feral, overgrown Earth, over which they hold only the weakest measure of control through their attempts to poison the planet's ecology to make it more suitable for themselves. Despite their efforts, some areas of the planet remain completely outside of their control, such as the Ostron safe haven and trading hub of Cetus or the secret Steel Meridian enclave known as Iron Wake. Several other planets fall under more complete control of the Grineer, such as the planet-wide factories of Ceres and Sedna, the underwater research laboratories of Uranus, and the occupied desert cities of Mars. They also have complete control over the space regions around the Earth and Saturn, as well as having outposts even in the outermost location of the Origin System, called Veil Proxima. Their main fortress, the home of the Twin Queens, is located on an asteroid constantly moving thanks to Fomorian engines, and is probably the most guarded place of the entire System.
They are people acting on ultimate xenophobia, fueled by hereditary madness, and a burning hatred of anything and anyone not like themselves and have absolute loyalty, not dissimilar from religious fanaticism, to their Queens, although very few have actually been granted the permission to see them. In the end, should they succeed, there will only be Grineer left alive in the Origin System.
In battle, the Grineer use heavy armor coupled with attrition and ambush tactics. While they are fairly weak individually, they are a potent threat in groups, able to lay down withering streams of fire at all ranges from behind cover. Specialist troops use more advanced weapons, and many are even issued comparatively advanced reactive armor and cybernetics to give them an edge.
The armor on an average Grineer deserves special mention because it makes them one of the toughest factions to face in a battle. Coupled with several elemental resistances and the fact that even the relatively common Elite Lancer is heavily armored makes them extremely durable, with their Medium and Heavy units becoming absolute bullet sponges at higher levels. Furthermore, their special corps tasked to defend their positions on space and to assault enemy ships such as Railjacks have even higher defenses. The Grineer also make notable use of rudimentary teleportation, either to transport small strike forces on daring missions even within hostile territory held by the rival Corpus, or on an individual level: their Flameblades utilize it to blink close to the enemy for a vicious melee attack, and Commanders employ an ability similar to the Switch Teleport of Loki to leave the victim confused and in the midst of the Grineer troops. Infamous Grineer officers who utilize teleportation are Tyl Regor, who blinks constantly to evade and confuse the player in his battle, and Captain Vor, who uses teleportation in battle to keep a distance from the player (though the latter's abilities might originate from his Janus Key).
Although notoriously known for their short lives, some selected Grineer units can be granted from their Queens the gift of immortality, in the form of their own blood, after facing a Warframe in battle. These super-soldiers called Kuva Liches, inherit some of the abilities of their "progenitor", as well as possessing a high level of adaptability and intelligence, making them by far the most powerful Grineer units to face.
- Main article: Category:Grineer Weapons
Fittingly for a military power like the Grineer, they have developed a wide variety of weapons and equipment used in their ceaseless conflicts with the Tenno, Corpus, and Infested. This ranges from simple pistols to heavier rifles, shotguns, and machine guns; to missile launchers, flamethrowers, melee weapons with superheated surfaces, hydraulically-assisted axes, hammers, and flail-like whips with hooked grinding blades.
Grineer weaponry are largely conventional or industrial in operation. Grineer aesthetics tend to employ a curved, rounded, and heavily plated spot-weld look. This is indicative of the extensive use of tough, temperature, and shock-resistant Ferrite and Alloys used in Grineer construction and manufacturing. As opposed to weapons built by the Corpus, Grineer weaponry are not laboriously cast or machined for precision, but instead pressed from molds, quickly filed down, and assembled by the billions, designed with loose tolerances to streamline the process. Many Grineer weapons also lack full stocks, and instead rely on their wielder's augmented strength and heavy armor to absorb the recoil.
Grineer weaponry are generally not designed to be used against the Grineer since they are simply too heavy or large for other races to utilize without the aid of something like a Warframe. They are also less effective against the Grineer since they are primarily engineered to deal Impact damage for use against Corpus shield systems and Slash damage for use against the Infested. Of course, Sentients with their adaptation abilities can efficiently resist to almost every attack of a Grineer weapon, and are for this reason studied and researched on, in order to develop even more advanced technology.
Despite their manufacturing processes being centered around mass-production, Grineer engineers are fiendishly clever in incorporating unusual and unorthodox ideas and new technologies into their weaponry, even if such technology is something they are unfamiliar with. An example of this can be seen in Captain Vor's Seer; this is a long-ranged pistol with sniper optics that incorporates Orokin technology. Other examples include the Jat Kittag - a Grineer warhammer that incorporates a series of jet engines to allow a more destructive impact.
Despite the best efforts of the Lotus, the Grineer have also developed primitive microwave and plasma-aided projectile weapons, as well as a rifle that fires guided projectiles. These weapons are reserved for the elite of the elites among the Grineer, such as the Nightwatch corps and the guards of their Queens' fortress.
The most powerful Grineer weapons are the ones used by the Kuva Liches, their super-soldiers, inheriting a percentage of elemental damage based on their progenitor. Some are just special variants of normal Grineer weapons, others are totally unique and with high-destructive power, such as a bow that shoots explosive arrows or a heavy weapon normally impossible to use on field.

The Grineer military forces are divided into specialized corps depending on their field of operations and combat tasks. As a rule, they tend to be camouflaged for the environment they expect to be fighting in.
The bulk of Grineer forces that are tasked with guarding Grineer mining and production facilities as well as manning their galleons. Basic in both armor and armaments, they are nonetheless among the most adaptable of the corps.
Grineer units specialized in desert warfare such as at their colonies on Mars. Their combat gear has been adapted to the dusty environments with the addition of air filtration systems and sand catching fabrics.
A Grineer special operations crew tasked with elite assignments throughout the Solar system. Rarely seen but well equipped, they use modified equipment to enhance their effectiveness in battle.
The Grineer royal guard corps stationed at the Kuva Fortress tasked with protecting their Twin Queens. The only time they are assigned to other locations is during Kuva collection. Their equipment tends to favor stopping power over rate-of-fire. (Kuva Larvlings, Thralls and Liches are special units and do not fall under this category)
Grineer have a dual classification system. Primarily, they are classified by their armor class - Light, Medium, and Heavy - which describe their base armor and their shared damage multipliers. Secondarily, they are classified by their role or engagement style. Light units primarily utilize melee weaponry and rush their attackers. Medium units use rifles and shotguns and tend to find good cover and engage at all ranges. Heavy units are normally outfitted with non-standard weapons (ex: Gorgon, Ogris etc.) and typically have various roles in combat based on their loadout.
Light Grineer units mainly consist of melee units with decent damage and low durability. Some have special abilities.
- Main article: Butcher
Butchers are Grineer units that wield single Cleavers. They lack the armor and ranged firepower standard Grineer units possess, making them much easier to kill; in exchange, they can move quicker and deal more damage with their melee weapons. Butchers will wind-up their attacks for a split second, making it possible for players to dodge.
- Main article: Flameblade
- Main article: Guardsman
- Main article: Powerfist
Powerfists are similar to Butchers, but use a single Furax instead. Like Flameblades, they tend to take cover until a player is close, which can allow them to ambush players. This is further aided by their faster sprint speed. Upon closing on players Powerfists will charge their melee to inflict massive damage, and then follows it up with a combo of quick melee. Powerfists have a much longer charge time than Butchers, but after their long charge they will attack like normal. They can also perform a powerful ground slam, knocking enemies up in the air and inflicting Electricity damage.
- Main article: Scorpion
Scorpions are female Grineer units that wield Machetes. They deal high damage with their Machetes, and have a grappling hook that they can use to knock down Tenno and drag them. The fast hooks, knockdowns and possibility of continuous hook-spamming by multiple Scorpions can make them a deadly adversary, especially when backed up by other units.
- Main article: Shield Lancer
Shield Lancers are defensive Grineer units that carry large iron shields in one hand and Viper pistols in the other. They slowly press forward while firing over their shields. Nearby Grineer will often use them as mobile cover to variable effectiveness. Shield Lancers will also use their shields as battering rams to knock players off their feet, often doing so when a player comes too close. Shield Lancers often will not charge players while providing cover for allies, but will charge when the units behind them die, or move away.
Medium troops make up the bulk of the Grineer army. They are not particularly dangerous when alone, but in groups they can pose a serious threat.
- Main article: Ballista
Ballistas are Grineer female units that utilize the Vulkar for long-range support. While they have a slower fire rate than other Grineer units, Ballistas deal more damage and are smaller targets.
- Main article: Elite Lancer
Elite Lancers are the Elite counterpart of the Grineer Lancers, and are found replacing the latter in mission levels 15 and up. Unlike the typical Lancers, they wield Hinds with a much higher damage than the regular Grakatas, as well as a high chance of Slash procing targets. Their armor is not only doubled in amount, but replaced by more resilient Alloy Armor compared to normal Lancer's Ferrite, the same armor heavy Grineer units often incorporate. They also have a slightly different helmet design, appearing to have a hood.
- Main article: Eviscerator
Eviscerators are Grineer units that were released with the Fomorian Event. They feature higher armor and health than the regular Grineer Lancer. The Grineer Eviscerator is equipped with the Miter that fires large saw blade projectiles, acting much like the Glaive when thrown. The saw blades bounce off surfaces and can be deflected by melee swings, being destroyed after bouncing a certain amount of times.
- Main article: Hellion
Hellions are medium armored Grineer units which are equipped with personal jet-packs that allow them to jet-jump across terrain quickly as well as hover high in the air, giving them mobility even greater than that of light units.
- Main article: Lancer
Lancers are the most basic and prevalent form of Grineer infantry. They wield Grakatas and occasionally throw Plasma Grenades. Although mostly inaccurate with their grenade throws, they can easily down a Warframe caught in the blast. Their armor is blue-green in color.
- Main article: Scorch
Scorches are medium Grineer units resembling Troopers with red and yellow armor. Scorches wield the Ignis flamethrower, dealing massive continuous damage in short range as long as the victim is in range. They can deal continuous damage and also set the player on fire, making them incredibly lethal in a successful ambush or when working with units such as Scorpions and Rollers that can inhibit player movement.
- Main article: Seeker
Seekers are tactical Grineer units with yellow-green armor and darker markings. Aside from using the Kraken pistol, they will also deploy Latchers. This ability makes them unlikely to rush into the front lines like any regular Grineer unit. More durable than regular Grineer Lancers, these can be versatile opponents.
- Main article: Trooper
Troopers are the shotgun-wielding counterpart to the Lancer. Armed with various shotguns, including Sobeks (and previously used Struns, which they are shown holding in the Codex), they lack the accuracy and range of Lancers and outfitted in more heavily armored yellow attire. This makes them comparatively more effective in close quarters, with shotguns and higher armor.
These units are the strongest and toughest of the Grineer. Apart from the Grineer Commander, these units don't take advantage of cover. Most Heavy Grineer cannot seem to retaliate while under attack, showing vulnerability to status effects; therefore it is possible to dispatch lone Heavy units easily with sustained firepower. Heavy units typically have significant base Health and armor.
- Main article: Bailiff
Bailiffs are heavily armored Grineer melee units introduced in the Project Undermine Tactical Alert. They are rare but dangerous units, capable of smashing through crowds and soaking up Corpus fire. Throughout the Tactical Alert, they are considered to be the Grineer answer to the Corpus Isolator Bursa. The Bailiff wields a custom-colored Jat Kittag, which they use during battle, and wears heavier frontal armor that bears resemblance to a hockey goalie.
The base variant can be rarely found in the Kuva Fortress.
- Main article: Bombard
Grineer Bombards wield the Ogris, whose projectiles have a minor homing ability; these rockets can be shot down. In larger areas, their rockets are more easily avoidable, but they can be quite dangerous in enclosed areas, due to the 4m blast radius of the rockets. They can be identified by their white/grey armor. They have a significantly high amount of armor, which makes most weapons without Puncture damage almost useless.
Like other heavy Grineer units, Bombards can also perform seismic shockwaves when players get too close, knocking them down with a radial blast. This ability has a long cooldown and can be used more than once over a long period of time.
- Main article: Commander
Commanders have much greater health than regular Lancers. They have the ability to Switch Teleport a targeted player; often, a Commander will teleport the player into the middle of a group of Grineer, causing some disorientation in the process. Unlike Loki's ability, a Commander's Switch Teleport can work through walls and doors and has a slightly longer duration stun.
- Main article: Drahk Master
The Drahk Master is a Grineer unit who can summon Drahk, vicious quadruped beasts that will attack their master's enemies.
- Main article: Elite Shield Lancer
Elite Shield Lancers are defensive Grineer units that carry large impenetrable shields in one hand and a Tonkor in the other. They are larger and more durable than their normal Shield Lancer variant and carry a shield with a distinct yellow coloring.
- Main article: Heavy Gunner
Heavy Gunners are cybernetically-enhanced female Grineer heavy infantry armed with Gorgon machine-guns. Identified by their taller, thinner frame and female voice, Heavy Gunners are capable of laying down suppressing fire to support their teammates. If left unchecked, they can tear through players' shields and health very quickly, especially on Warframes with lighter armor.
- Main article: Hyekka Master
- Main article: Manic
Dashing in for quick strikes before falling back to the shadows, the Grineer Manic is difficult to catch and deadly to ignore. Although only a few Manics will spawn in a given Grineer mission, its speed and damage make it a devastating enemy to face.
- Main article: Manic Bombard
Manic Bombards are modified Grineer Bombards developed by Tyl Regor, introduced in the Operation Tubemen of Regor Event as the event's main mission target. After Update 17.0, they can be encountered primarily on Uranus Sabotage missions, though they may occasionally spawn outside of them.
- Main article: Napalm
Napalms are yellow/red jacket-armored Grineer using incendiary grenade launchers that shoot slow, incendiary explosives, which leave temporary fire hazards when they explode. These hazards act like Ember's Fireball ability making them very dangerous in confined spaces. Their flame attacks also have a Heat AoE explosion in the range of 4m radius, allowing them to hit even the most agile players.
- Main article: Nox
The Nox is a type of Grineer "Chem Strike" unit. They wield a poison-filled heavy gun that shoots blobs of toxic sludge which stick to targets and surfaces before exploding. Bloated and disfigured by the very chemicals they wield in combat, these vicious warriors wear crude, heavily armored suits that both protect them and serve to contain the noxious clouds they emit. Breaking the glass cover protecting their heads both releases this poisonous aura and exposes them to headshots. Beware of their final moments however, as they explode into a lethal cloud upon death.
Executioners are Grineer warriors consigned to the service of Kela De Thaym, responsible for enforcing her rule in Rathuum. Armed with a variety of deadly weapons and skills, Executioners ensure that the accused on trial are given swift and brutal deaths.
The utility enemies of the Grineer are dangerous in their own right, such as the Roller, one of the most infamously annoying enemies in the game.
- Main article: Arc Trap
Similar to the Nervos Mine, the Arc Trap is a Grineer device that attacks hostiles that get too close via an Electric arc. The trap can be destroyed by your weapons, generating a burst of electricity that damages and stuns nearby opponents and allies. They will also destroy themselves after 3 seconds of continuous shocking. They were added in Update 12.5 as a replacement to Broken Lights.
- Main article: Drahk
The Drahk is a quadruped beast bred by the Grineer for use in combat. Its behavior is largely similar to Feral Kubrow.
- Main article: Hyekka
The Hyekka is a Kavat breed developed by the Grineer for use in combat. It appears to be a hairless version of the Kavat, with a stubbier snout and a stouter appearance. In addition, it only has one tail, as opposed to the many feathered tails that usually adorn the rears of feral Kavats.
- Main article: Latcher
Latchers are small autonomous grenades deployed by Grineer Seekers that will chase a player in an attempt to latch onto them and then detonate. Latchers can be destroyed before they reach their target, but their small size and speed make them very difficult to shoot. If one is attempting to shoot a Latcher preemptively, the ideal situation would be to stand on a platform tall enough to avoid their jump height, as they occasionally stop moving when they cannot reach their target. If the Latcher latches onto you, you can remove them by rolling (default ).
- Main article: Power Carrier
Power Carriers are special units found only on Excavation and Defection missions. These units are mostly identical to their standard base units, though they feature greatly improved health, and visibly carry Power Cells on their backs. Killing these units will make them drop the Power Cells they carry, allowing Tenno to recover them for use in powering their Excavation machines or Med Towers. The Grineer version are based off Lancers, the Corpus version are based off Crewmen, and the Infested ones are based off Mutalist Ospreys.
- Main article: Regulator
Regulators are floating Grineer support drones found in Grineer Settlements. They can be deployed by any Grineer units and their propaganda broadcasts provide allies around them with a buff similar to Rhino's Roar. This will give the units in range increased damage and speed, and disrupt the player's mini-map.
- Main article: Roller
Rollers are simple Grineer machines that resemble larger-sized Latchers. Unlike their smaller counterpart, Rollers will jump at players, bludgeoning and staggering them, and will continue to attack the player until they are destroyed. Rollers are sent as a syndicate death squad by Steel Meridian.
- Main article: Sensor Bar
Similar in nature to Corpus Laser Barriers, the Grineer Sensor Bar is located above some doorways in the Grineer Galleon tileset. It projects a field across the opening of the door which will deal damage and inflict a Magnetic proc, draining energy and temporarily reducing shields. Destroying the green sensor light will disable it, allowing safe entry.
- Main article: Grineer Target
The Grineer Target is the objective of Grineer Capture missions. There are 6 different types of targets that are variations of normal Grineer units with different color schemes, with the default Grineer Target being the exception. Some of these targets have their own special abilities. Each Target is armed with different weapons.
They drop small amounts of credits when shot or meleed.
- Main article: Warden
Wardens are special units that appear in Rescue missions, tasked with protecting prison complexes where hostages are kept. They appear as Heavy Gunners or Ballistas for Grineer missions, Corrupted Heavy Gunner for Orokin Moon missions, and Sniper Crewman and Corpus Tech for Corpus missions, and are more durable than normal units. They are however highly vulnerable to stealth attacks and takedowns.
Various defenses are utilized by the Grineer, ranging from pre-spawned turrets or inflatable, deployable cover.
- Main article: Blunt
The Blunt is an item occasionally carried by some Grineer units during missions, visible as a large backpack with orange lights. When deployed, the Blunt inflates into a small, black barricade that Grineer units can use as cover to defend from enemies, and which can be deployed anywhere on the map. The Blunt itself has a limited amount of health (which depends on the level of its user), and unlike environmental cover can be destroyed but only with melee attacks. A Blunt can only be deployed once per unit and once deployed it will slowly start to "deflate" (lose health) on its own.
- Main article: Rampart
Ramparts are emplaced defensive turrets found on Grineer missions, armed with twin heavy machine guns to engage enemies. Unlike other types of environmental defenses, Ramparts can be directly controlled by Tenno players by mounting inside them with the Use key (default ), allowing them to use the Rampart's guns. While Ramparts are rooted to their positions, they can be aimed at nearly every direction.
The Ghouls are hastily-bred Grineer clones grown in diapause bags dropped in from space and buried in the ground. These deformed monstrosities may be lacking in typical qualities like intelligence, sanity or longevity, but their sheer numbers, ferocity and deadly weapons more than make up for it. With paralytic blood, ghouls remain a threat even after they have died.
- Main article: Ghoul Auger
The Ghoul Auger is a Grineer Ghoul armed with drills that allow it to quickly dig underground and ambush their foe. Attached to these weapons are fuel canisters, doubling as a flamethrower. As with all Ghouls, on death they will release a cloud that inflicts Cold and Toxin.
- Main article: Ghoul Devourer
The Ghoul Devourer is a Grineer Ghoul that is considered Vay Hek's personal favorite. Despite its massive girth, it is armed with a powerful wrist-mounted hook that allows it to close the distance between it and its target. As with all Ghouls, on death they will release a cloud that inflicts Cold and Toxin.
- Main article: Ghoul Expired
The Ghoul Expired is a Grineer Ghoul that suffered from malnutrition or poisoning during the early parts of its development, causing their nervous systems to drive them forward and function as an ideal suicide troop. Aiding them in this task are a pair of shields with multiple bomblets strapped on. As with all Ghouls, on death they will release a cloud that inflicts Cold and Toxin.
- Main article: Ghoul Rictus
The Ghoul Rictus is a Grineer Ghoul armed with a large saw. These saws can be ejected similar to the Panthera's Alternate Fire, traveling a distance before returning to them. The Rictus also has the uncanny ability to ride on the ejected saws, allowing them to approach and ram their enemies from afar. As with all Ghouls, on death they will release a cloud that inflicts Cold and Toxin.
These are troops which are deployed in the Archwing game mode.
- Main article: Dreg
Dregs are Grineer combat spacecraft found in mining asteroids. Their primary weapon is a spherical projectile that homes in on its target and then explodes with small AoE with the chance of a Blast proc.
- Main article: Lancer Dreg

- Main article: Draga
Draga are the simplest and most-common of the aquatic enemies which can spawn in underwater areas of the Grineer Sealab tileset. They wield the Harpak and usually move fairly slowly through the water, though they will move faster upon spotting a player.
- Main article: Darek Draga
Darek Draga are a more dangerous foe than the Draga, due to their usage of the Kulstar cluster-rocket launcher, which can be rather difficult to dodge due to a combination of Archwing movement-methods and the often-cramped environment of the submerged caverns beneath the Grineer Sealab tileset.
Also, when alerted, the Darek Draga releases a cloud of brown smoke, limiting visibility of it and nearby Draga, Shock Draga and Sikula, which can prove fatal if caught in the cloud, due to the Sikula's mines.
Potential threat to players if they are caught unaware, are in an enclosed space or if they are preoccupied with other enemy units.
These units appear in the Empyrean game mode. Kosma units are deployed on Earth Proxima, Gyre on Saturn Proxima and Exo on Veil Proxima. Almost all the units have Elite counterparts appearing in higher-level missions.
Single person attack crafts, attack in waves.
- Main article: Cutter
Cutters are Grineer fighter craft in Railjack missions. They appear in large groups, mainly focusing on swarming a player's Railjack and weakening their defenses. Their hulls are weak and can be taken down fairly quickly with the ship's turrets. Their defenses are near impenetrable if using an Arch-gun that is not strong enough, and a direct approach should be taken into consideration before deploying out of a Railjack. There are three types of cutters that will be encountered over the course of progressing through the Proxima planets of the Origin System that have varying color palettes as well as unique drop tables.
- Main article: Flak
Flaks are Grineer fighters in Railjack missions. They appear in medium groups, mainly focusing on dealing high damage to the Railjack. Their hulls are stronger than other interceptors, but they can be taken down in a reasonable amount of time with the ship's turrets. Their defenses are near impenetrable if using an Arch-gun that is not strong enough, and a direct approach should be taken into consideration before deploying out of a Railjack. There are three types of flaks that will be encountered over the course of progressing through the Proxima planets of the Origin System that have varying color palettes as well as unique drop tables.
- Main article: Taktis
A Taktis is a type of Grineer fighter in Railjack missions. They appear in small to medium groups, mainly focusing on dealing long-distance damage to the Railjack. Their hulls are weak, and they can be taken down fairly quickly with the ship's turrets. Their defenses are near impenetrable if using an Arch-gun that is not strong enough, and a direct approach should be taken into consideration before deploying out of a Railjack. There are three types of taktis that will be encountered over the course of progressing through the Proxima planets of the Origin System that have varying color palettes as well as unique drop tables.
Feature higher armour and have more powerful, unique ways of attacking.
- Main article: Outrider
Outriders are Grineer heavy fighters encountered in Railjack missions. They are equipped with heavy armor, making them nearly impervious standard weapons fire. They can only easly be destroyed with Munitions, or by specifically targeting the glowing weakpoints located on their fuselage.
Heavily armoured and almost impenetrable to normal attacks, these ships feature a crew and can deploy Ramsleds.
- Main article: Gokstad Crewship
Gokstad Crewships are heavily armored Grineer troop transport ships, found in Empyrean missions, that can only be destroyed by the Railjack's Forward Artillery or internal reactor sabotage. They sport homing missiles commanded from three posts, and can be boarded to take command of those posts, pilot the ship, or destroy the central reactor. In addition, they can fire up to four Ramsleds in an effort to board the player's Railjack.
- Main article: Ramsled
Ramsleds are Grineer boarding capsules in Empyrean missions. These capsules will home-in on Railjacks, and on collision will deploy Grineer crew to attack the Railjack from within. Each Gokstad Crewship and the mission's Point of Interest(s) will deploy up to 4 Ramsleds.
Cephalon Cy will announce when a Ramsled has been deployed, and if the boarding party has successfully entered the Railjack.

- Main article: Bosses
Bosses are officers within the Grineer faction.
- Main article: Captain Vor
Captain Vor is the Grineer officer responsible for the players' awakening in the opening moments of WARFRAME. He is one of the few figures in the Origin System that understand ancient Orokin technology, and is capable of utilizing it and merging it with Grineer technology to create offensive weapons such as his trademark Seer pistol and his armor, powered by a Void Key that he refers to as the "Janus Key", which also grants him a powerful ranged beam attack, impenetrable shielding and the ability to teleport.
Captain Vor can be encountered in three locations currently, making him the most recurring boss in the game aside from the assassins. First appearing at the end of the Vor's Prize quest and thus being the first boss that players must fight, he also serves as the boss of Mercury; he then appears again on Ceres alongside Lieutenant Lech Kril; then appearing later yet again as a Corrupted version of himself within the Void.
- On Tolstoj, Mercury, a successful assassination will reward the Seer blueprint and components upon his defeat, and may also drop Orokin Cells. There is also a small chance of being rewarded a Cronus blueprint.
- On Exta, Ceres, the player will receive Frost component blueprints and either Miter parts or Twin Gremlins blueprint.
- Main article: Councilor Vay Hek

- Main article: Grineer Language
The Grineer speak and write in English, however they use their own unique set of barcode letters with dot-matrix-styled 'cuts' made along its edges (left for letters, right for numbers), to various depths. A dot present under each letter's bottom-right corner helps to determine the correct orientation and makes it easy to tell if the text has been flipped or rotated.
- Before Update 10.0 was implemented, the Grineer troops used to speak fluent English, which was then changed to the Grineer language in order to retain the lore of the Grineer aggressively disliking anything not Grineer.
- One of the more infamous voice lines from pre-Update 10.0 Grineer was "Combat formation Bravo!". It was jokingly explained by a DE staff member that a key requirement of Formation Bravo is to never mention anyone's mother. Other joking fan interpretations of Formation Bravo refer to the "enemy tower" bug, where enemies would spawn on each other's heads.
- Other popular lines from pre-Update 10.0 were "Stay close to the walls." and "Hey, leave my mother out of this."
- So far, the Grineer are the only voiced faction to have a strong direct aggression against the Tenno, speaking their name during their attacks in their language.
- They also have been heard saying Waframe, as in Warframe, when spotting one themselves.
- The same applies to many phrases the Grineer use, such as yelling "attaf!" instead of "attack!" and "ket clem!" instead of "get them!" (The Grineer word "clem" has been created into a fictional fan character whose name is the word itself. DE has stated in a Devstream that he is the Medallion Merchant for the Steel Meridian in their syndicate room as well.) Clem was later added to the game as a full character.
- In essence, Grineer still speak English, but since Update 10.0, it has been adjusted to account for their decaying flesh and how that might affect their speech, essentially giving them a speech impediment.
- In a Devstream, DE has stated that the Grineer are British. However, this might only be a joke regarding their language and their loyalty to the Twin Queens. They also share similarities to the Lasrian troops from Dark Sector.
- When playing an Invasion mission, while the player has sided with the Grineer, they still will cry out quotes like Tenno Scum, because although the AI is allied with the player the voice choices still do not alter. The same goes with Shadow Grineer, shouting at other Grineer the same anti-Tenno aggressive lines.
- The Corpus nicknamed the Grineer as the "dogs", not because of their degraded appearances but to their aspect of extreme servitude towards their leaders (and possibly creators), the Twin Queens. This was mentioned by Alad V during The Gradivus Dilemma.
- Their name "Grineer" seems to be a portmanteau of the words "Genetically" and "Re-engineer" which makes sense given the lore behind them.
- The name "Grineer" may also be derived from the title of a folkloric monster known as Seigneur du grenier, a French version of the Bogeyman myth.
- In Update 13.2, the female Grineer received an audio overhaul. Speaking in a deeper and more aggressive tone, with long pauses and slurs, adding viability to their genetic deterioration.
- Despite the Grineer being a xenophobic race, in the trailer for Vor's Prize, which was shown at the end of Devstream 32, Captain Vor and the Twin Queens are heard speaking in English. Sargas Ruk and a number of other notable Grineer speak the language as well.
- As evidenced by Grineer Lancer's Synthesis imprint, the Grineer existed in the same time period as the Orokin. This is further confirmed by the Arid Eviscerator's imprint, which also confirms the Orokin created the Grineer for slave labor. Originally clone servants used for hard labor, they were militarized by their masters in a desperate attempt to beat their enemies in the Old War.
- The Operator will also mention that "the Grineer used to be builders."
- According to the Landing Craft's Scanner, the Grineer use Solar Rails, possibly in a sort of ongoing partnership with the Corpus (who are known to be the faction controlling the transport network) or a fraction of them; while the Rail Control dispatcher's voice sounds closer to Corpus, he always closes his communications with "Glory To The Queens". They also control mining colonies by attacking them and killing anyone that opposes them (e.g. Rebels).
- For some reason most all of the Drekar Grineer units have the Operator eye guard cosmetic on their left eye.
- In a new Warframe trailer aired during TennoCon 2019, a Grineer depicted in the trailer shows no sign of genetic deterioration, whose concept art was later shown during Devstream 129.
- The event in the trailer is presumably at least a millennia before the Tenno went into their long stasis sleep and awakened at the current timeline.
