WARFRAME Wiki

You're still in the clear. No detection from enemy sensors.

When Warframes are not detected by enemies, they are in stealth, able to sneak past combat encounters or perform devastating attacks to unsuspecting targets. However, conspicuous activity will raise the alertness of observant enemies, which can increase the difficulty of the mission. At various levels of alert, enemies may become more careful, call for help from other nearby enemies, or trigger the alarm control panels to summon backup from other rooms. Alertness decreases over time.


While most missions in WARFRAME do not require or explicitly reward stealthy play styles, the game provides an assortment of weapons, mods, and a different damage multiplier that enable an alternative gameplay option for advanced players who seek immersion or challenges.

Alertness[]

Enemies can only see things in a short, frontal cone and their view can be further restricted by the environment. They are bad at noticing threats at a distance or anyone somewhat above their heads. Crouching will hide a Warframe's silhouette well, and being cloaked (invisible) allows the Warframe to move past enemy eyesight without triggering any suspicion. Loud noise, however, can cause enemies to fire towards invisible Tenno–shooting most weapons while visually shrouded will still alert nearby enemies from all directions. Also note that having a Companion equipped makes you much more noticeable from a longer range, especially if it has been equipped with an aggressive mod like Assault Mode

Distant gunfire or suspicious activity (such as noticing the corpse of an ally or a silent weapon hitting the terrain) may temporarily put enemies in nearby map tiles into a minor alert. These enemies keep watch from behind cover or patrol with guns raised and are more sensitive to the Tenno presence. As they don't know exactly where their threats are, they are more cautious, looking down corners and expanding their vision. This can usually be heard by the player, as enemies talk to each other while in this state. From this state and above, enemies can no longer be Stealth Attacked until their alertness level lowers below a minor alert.

Enemies in a tile enter full combat alert when they see or hear the Tenno directly, are directly shot at, or hear a loud weapon being fired. In this state, they will attempt to pursue the Tenno while getting backup by summoning nearby allies or activating alarms via control consoles. Enemies from other tiles will not enter this state if the enemy detecting the Tenno is killed quickly enough and the alarms are not triggered. Additionally, their range of vision expands and they will be able to spot Tenno and their companions from far away, even after the player disengages from combat. Note that backup troops arriving in nearby rooms may not know what the threat is, and will be put into minor alert instead. Players can infer an ongoing full combat alert from how enemies will notice and fire upon the player from much further away than before.

Infested and Corrupted enemies are exceptions because of their hive-mindedness. They will not use manually activated alarms, but once even one unit reaches full combat alert every other unit in a huge range will enter minor alert too. And, since there are no alarms, it is not possible to remove alerted states. New enemies may still spawn unalerted though, and minor alerts work as usual.

The minimap will change color depending on the alertness of the room's occupants with White, Amber, and Red referring to enemies being unalerted, in a minor alert, or a full combat alert respectively.

When a Tenno or allied NPCs come out of invisibility, their enemies will take a full second of delay before noticing them, regardless of their alert state.

Control Panels[]

Main article: Hacking

Control consoles are liberally scattered around most tilesets. If activated by an enemy, it will alert the entire room and may spread the alert to the whole map. Killing the enemy before they finish using a control panel (they take about 1.5s to complete the alert) will prevent the alarm from sounding. Enemies will not consecutively run towards the same console to set off the alarm, but if the fight takes long enough, another enemy will likely attempt it. Note that if the enemy activating the alarm takes enough damage, they will abort activating the alarm and turn to attack the Tenno. If an alarm is set off, the alarm can be reset by going to another control terminal and hacking it without further spread of notice. While it is possible for stealth to be recovered in missions populated by the Grineer and Corpus, the Corrupted and Infested factions do not use control consoles to sound alarms and any open detection will result in these factions' enemies becoming alert in a very large radius.

Even when the control panel has been accessed and an alarm has sounded, enemies will lose track of the Tenno when the last group of enemies killed is not close enough to set the next group of enemies on alert. They will wander as if they never heard an alarm. By sprinting through rooms quickly, one can sometimes avoid alarms being set off or escape to new rooms distant enough from the hostile room arming its alarm that these new enemies won't hear it. Equipping a sprint speed mod such as Rush12?cb=20190608095452 Rush on the Warframe can increase this chance of escape.

Security Cameras and Turrets[]

Main article: Security Camera

Cameras can detect Tenno and deploy any nearby Corpus Turrets to engage in combat. However, triggering a camera or shooting a turret will not trigger any kind of alertness for other enemies, nor will the general alarm state in the mission cause the security cameras to be alerted. The challenge reward for 10 stealth kills can easily be accomplished in high-alarm scenarios by destroying cameras that haven't personally witnessed the player. The turret, on the other hand, is hard to destroy if never activated but note that its shots are silent and do not alert the enemies in nearby rooms.

Stealth Damage Bonus[]

Standard melee attacks are affected by a +700% stealth damage bonus when attacking enemies that are unalerted, made vulnerable to front/back finishers by a stun, or that are otherwise unable to detect players due to being blinded or under the effect of BansheeBansheeIcon272.png Banshee's SilenceSilence130xDark.png Silence, as well as if the player is cloaked by an ability (e.g. InvisibilityInvisibility130xDark.png Invisibility). This damage increase changes the color of regular damage pop-ups from white to yellow (similar to critical hits).

Stealth Melee Damage = Weapon Damage × (1 + Stealth Damage Bonus)

Enemies are not always susceptible to increased melee damage for every melee attack. If the player comes into physical contact with an enemy while attacking it, the damage bonus will be temporarily removed. Attacking from different angles and giving the enemy some distance will help improve the consistency of the attack damage. As long as you are invisible, the bonus will reset 3 seconds after an interaction with an enemy (Shooting, melee attack, physical contact).

The Stealth Damage Bonus is affected by the rank of the weapon. Rank 30 weapons deal 700% bonus damage, while unranked ones only gain 100%. In between that the bonus scales linearly as per the formula:

Stealth Damage Bonus = 1 + (6 ÷ 30) × Weapon Rank
Stealth Damage Bonus = 1 + 0.2 × Weapon Rank
Bonus does not scale beyond rank 30.

Critical hits while under these effects will still appear yellow or in their respective color for higher crit tiers. The damage bonus from crits and stealth stack additively with each other.

Stealth Melee Crit Damage = Weapon Damage × (1 + Stealth Damage Bonus + (Crit Multiplier - 1))

Stealth Attack[]

Main article: Finisher#Stealth Attack
Sneak Prompt.jpg

As long as an enemy is unaware of the Tenno presence, a stealth attack may be executed on them. To perform a stealth attack, the player must approach an enemy from behind and activate the stealth attack prompt. Successfully performing a stealth attack will deal a massive amount of damage during a special animation, during which the Warframe is immune to damage and will not be attacked by enemies. The attack's final damage depends on the melee weapon type used, on top of the 8.0x melee damage multiplier described in the preceding section.

Stealth Attack Damage = Weapon Damage × Stealth Multiplier × Weapon Multiplier

As these multipliers factor total weapon damage, equipped mods (including critical chance and critical damage mods) will also affect the stealth attack's final damage. Stealth attacks inflict True DamageDmgTrueSmall64.png True Damage, which is unaffected by armor. Damage value pop-ups always appear yellow, identical to critical hit damage values (even if the stealth attack did not crit).

A complete kill ensures your target cannot recuperate and bring attention to you. Performing an unsuccessful melee stealth kill (which happens often when in a high-level area) or failing to kill an enemy with a silent ranged attack or ability will alert the enemy after a short moment. Due to that short moment, though, it is possible to execute consecutive stealth attacks by pressing melee key quickly right after the previous stealth attack is finished. This is also noteworthy for eliminating pairs or groups of enemies, as enemies within 5 meters of the victim will become cautious (even without seeing the Warframe) for roughly 20 seconds due to the sound of their comrade's death.

Enemy Eligibility[]

Bosses can indeed be stealth attacked.

Some enemies do not grant a stealth attack prompt. Many mechanical or robotic enemies are immune to stealth attacks, either completely or from specific weapon types.

Grineer

Corpus

Formerly MOAs would not grant a stealth attack prompt, but through updates this has been changed, and now have stealth attack animations for every class of melee weapon.

Formerly, humanoid Bosses were vulnerable to stealth attacks. This has been phased out over time, and only The Sergeant can still be stealth attacked. Non-humanoid Bosses such as Phorid and Jackal have always been immune to stealth attacks.


Special Warden enemies take bonus damage from stealth attacks, allowing a larger chance of instantly killing them, which is crucial in order to complete their host mission with the most points. This is especially useful since Wardens have very high health and will trigger the execution sequence if the player is spotted.

Affinity Bonus[]

Killing a target with a stealth finisher attack will trigger a Stealth Kill Affinity Bonus, which increases the amount of affinity that a player gains from killing said enemy. A notification appears in a player's HUD to the left of the shield counter upon performing a stealth kill, which will display the bonus affinity value for that kill, as well as the time remaining for the combo duration of 30s. Each successive stealth kill will refresh the combo counter and grant 100% more affinity towards the next kill, stacking up to 500% bonus affinity after 5 stealth kills.

The stealth kill affinity bonus resets if the Warframe kills an alert enemy or is attacked by an alerted enemy (Companions, Sentinels, and Operators do not reset the bonus). Only enemy units will trigger these affinity bonuses. Environmental objects like Corpus Turrets, Security Cameras, Sensor Bars, and Storage Containers will not reset the multiplier nor do they count as a stealth kill. Certain units like Sensor Regulators are also considered objects, and thus will not initiate stealth affinity bonuses.

Oddly enough, certain Warframe powers (like ParalysisParalysis130xDark.png Paralysis) and Melee Combos that initiate stagger may initiate stealth kill affinity bonuses upon performing a Finisher, even if the enemy was previously aware of the player.

Fighting Silently[]

Main article: Noise Level

Using noisy weapons and abilities will alert enemies within 50m. Equipping max-rank Suppress12?cb=20190608095452 Suppress, Hush12?cb=20190608095452 Hush or Silent Battery12?cb=20190608095452 Silent Battery will render any pistols, rifles or shotguns completely silent.

Silent or Quiet Weapons[]

All melee weapon attacks are silent, including those from thrown weapons, the DeconstructorSentinelGlaiveWeapon.png Deconstructor, and the shotgun attack of the RedeemerTnoGunblade.png Redeemer (as long as enemies are more than 5 meters away from the player when it is fired). The following ranged weapons are also innately silent or otherwise produce less noise than standard when fired:

Silencing Mods[]

Tips[]

  • It's not recommended to bring a companion when playing stealth without a way of cloaking (becoming invisible) yourself, as crouching may reduce enemy visibility for you, but it does not affect your companions and could still leave them in enemy sight.
  • Be patient and learn the behavior of your enemies. Good timing means you can avoid patrols and position yourself to attack enemies from behind.
  • Check your surroundings to sneak up on an unsuspecting enemy without interruption. Do not eliminate an enemy if it is being watched by another enemy. If enemies see a corpse that has not disappeared yet, they might be alert for a short period of time.
  • In large rooms, look for exposed ceiling rafters or ventilation shafts that can be used to traverse areas without the risk of directly encountering enemy patrols.
  • Always allow at least a two-meter distance between enemies before engaging them in melee as a precautionary measure.
  • Staggered enemies don't make sounds, but they become alert and will alert others if given a chance to recover. If you did not kill an enemy with a single hit, keep it staggered by stealthy means and you'll be fine. Cold DamageDmgColdSmall64.png Cold procs will lengthen the amount of time an enemy stays staggered.
  • Stand to the side of a door to open it and peer slightly by moving the camera. You can see around the left edge of obstacles by changing the camera to hang over your left shoulder (default is H ).
  • Having a Sentinel equipped may compromise stealth, as it does not hide behind low cover. If you do bring a Sentinel, make sure to remove their targeting precept mod or the weapon itself. The only exception is Shade's Revenge12?cb=20190608095452 Revenge, which will not target enemies unless they are attacked players.
    • If you have a Shade with the Ghost12?cb=20190608095452 Ghost ability, consider sprinting toward an enemy to activate it quickly.
  • Sniper Rifles and other long-range weapons such as the LatronLatron.png Latron are less likely to attract attention. This is most likely because the weapon noise at the gun's barrel is far greater than the noise at the impact site.
  • Use a Codex Scanner or Synthesis Scanner. Scanners can show enemies within 50 meters through walls and behind cover. However, if used to scan, it will remove the scanned enemies from the player's view.
  • Practice stealth play on low-level Extermination missions. As players will usually one-shot almost all enemies, they will get the hang of silent weapons, the enemy's cone of vision, and other things that would be difficult to practice with the most difficult of missions.
  • Try doing stealth missions solo, as various players that may join mid-round may not agree with taking a stealthy approach to a mission. A solo player is also able to improve on their mistakes and their mistakes alone.
  • If going invisible in Corpus stealth missions, be very careful of Nullifier Crewmen and Fog Combas and Scrambuses, as they can disable a Warframe's invisibility powers.
  • Unalerted enemies that are sent to sleep by EquinoxEquinoxIcon272.png Equinox's Rest and IvaraIvaraIcon272.png Ivara's Sleep Arrow can be killed using automatic weapons that deal weak damage per shot without alerting them, as long as the enemy is killed quickly enough after passing their waking damage threshold. Both abilities can also be used on clustered enemies to prevent them from being alerted by kills made in their proximity.
  • The fiery battle damage environmental hazard will spawn extremely alert enemies at the start. To resume stealth, kill all alert enemies in the area quickly and hack the nearest panel to reset the alarm. They will revert to an unalert state after some time. If the alarm is not reset, all enemies will spawn in the alerted state.
  • Sources of enemy radar, such as Enemy Sense12?cb=20190608095452 Enemy Sense or Enemy Radar12?cb=20190608095452 Enemy Radar, reveal enemies within range on your minimap as red arrows indicating position, general facing, and alertness level. Use this information when available to gauge the situation and plan how to proceed in a stealthy manner.

Bugs[]

  • After Hotfix 25.8.1 (2019-10-09), only stealth finishers could receive a bonus, though no mention of this change was made in any patch notes. As of a recent patch, proper stealth bonus functionality returned.
  • With projectile-based weapons, (Primary, Secondary weapons, AND thrown melee kills) enemies will see the projectiles and become alert.
  • The practicality of attempting an assassination on heavy and shielded units, especially purely mechanical enemies such as Corpus Ospreys.
  • If you aren't at the same altitude as the target, the prompt will not easily appear.
    • Being at a lower altitude will teleport the enemy to your current location, possibly causing them to overlap with walls. This usually happens on the stairs.
  • A Prompt will appear and disappear unexpectedly when the enemy is alerted.
  • After each stealth attack, you finish standing up, which might reveal your position. You will need to release and re-press the crouch button to return to the crouch position. If you are using a toggle crouch key, simply press it during the animation to return to crouching when the attack completes.
  • Dropping off a ledge will also cause you to stand upon landing.
  • A glitch can occur when stealth attacking Infested Ancients, Heavy Gunners or Corpus Techs. Upon entering the stealth attack animation, the enemy will shrink to roughly the player's size. (This shrinking glitch can also occur when using AshAshIcon272.png Ash's Blade StormBladeStorm130xDark.png Blade Storm. Blade Storm has a possibility to also shrink Grineer soldiers, as well as a few bosses, including Lieutenant Lech Kril.)
  • It is possible to attempt a stealth finisher without a melee weapon. This uses the finisher animation of nikanas but does very little damage.

Main article: Enemy Behavior
  • For a long time, it was possible to notice enemy spawn points (usually in Survival missions) and continue to fire your weapon under stealth to gain continuous stealth bonus experience, allowing quick leveling and Focus affinity.
    • To counter this, a mechanic was introduced wherein newly spawned enemies have a hidden timer active. This timer, which can be around 4-8 seconds or in rare cases indefinitely, causes killing this otherwise unalerted enemy to not count as a stealth kill and thus will reset any stealth bonus multiplier you have if this enemy is killed. This is why players may notice that despite all enemies being unaware of your presence, killing them all at once with an explosive weapon will often not give you any stealth affinity, or lose your current stealth multiplier.

Patch History[]

Update 27.1 (2020-02-04)

Hotfix 25.7.6 (2019-09-18)

  • Enemies may now “react” (without changing their Alert state) to you by stopping and looking around if you shoot a Silent weapon within 2-3m of them several times quickly.

Hotfix 19.6.3 (2017-01-17)

  • Enemies no longer receive a mental perception of an attacker, but rather mental perception of the source object. This causes them to play a reaction and become alert, but not have any extra information about the player. Enemies that are shot with projectiles that are silent and/or without a sound effect will now report a visual perception (rather than doing nothing). Previously enemies knew the exact location of their attacker when taking damage, regardless of the source.

Update 16.0 (2015-03-19)

  • Fixed stealth weapon XP multipliers increasing the stealth combo xp multipler as per: this thread

Update 15.13 (2015-02-05)

Stealth Finisher/Affinity Updates:

Joining our updated Spy 2.0 are some exciting improvements to stealth combat! Players will now find that sneaking around each Mission may come with some excellent rewards. These alterations to stealth gameplay will continue to evolve based upon player feedback, but for now stealth aficionados can sink their teeth into the following changes:

  • Stealth Streaks are here! Stealth kills can now receive Affinity multipliers if done in succession. Players will have 30 seconds from one stealth kill to the next to increase their Affinity multiplier, which goes up to 5x for melee and 2x for Ranged!
  • Finisher damage will now increase based on weapon rank and enemy level. Finisher Damage for stealth kills capped at 8x damage with max rank melee weapon!
  • The UI will inform you of your Stealth Streak where buff timers are usually located!

Update 9.5 (2013-08-09)

  • Added Stealth Finishers for Infested Ancients.

Update 7.0 (2013-03-18)

  • Stealth Attacks - sneaking up on unaware enemies now yields stealth attack options with melee weapons.
  • Stealth improvements - AI reaction and alert states have been tuned to make stealth play more viable.
