The Penta Launcher fires up to five grenades that can be remotely triggered at just the right moment.

Penta is a Corpus Grenade launcher. It launches ballistic grenades with primary fire, and detonates all active grenades with the Zoom feature.

Damage listed in game is damage from physical grenade impact with a target. The explosion is significantly more powerful.


Advantages :

  • Grenades deal Impact damage when hitting an enemy.
    • Deals 50% more damage to shields.
  • High AoE Damage.
    • 350 Blast damage that can be increased by mods.
    • A maxed Firestorm increases the blast radius up to 6.2 meters.
  • Very ammo efficient.
  • Heavy Caliber does not significantly reduce accuracy.[citation needed]
  • Explosion can also cause procs. 
  • Less explosion damage results in less damage dealt to self in comparison to the Ogris. Although damage and elemental mods will apply full damage to the user.
  • If three shots proc multi-shot from Split Chamber, there will be 6 grenades. (Needs testeing to see if all six deal damage. The extra projectiles are only noticeable if using Heavy Caliber at a high rank.)

Disadvantages :

  • Explosion deals Blast damage, which cannot be changed into another type.
    • Blast deals 25% less damage to Armor.
  • Impact damage of the grenade deals 25% less damage to flesh.
  • Can only have five grenades out at once.
    • When using the Split Chamber mod, the extra projectiles count towards the limit of five live grenades.
  • Grenades that have stopped moving have no obvious visual or audio cue (but with "PhysX" enabled they have some sparks when come to complete rest).
  • Grenades have slow projectile speed travel time and heavy arcing.
  • Grenades have a high bouncing capability which makes it hard to stack on desired spot.
  • Increasing magazine capacity does not allow you to have more than 5 grenades out at once, and after detonating the maximum of 5 at once you will have less to start in the magazine, forcing you to reload to shoot another 5.
  • Explosion cannot deal a critical hit (however the projectile can).


The Penta can be purchased for Platinum64150 and the blueprints for Credits6430,000.

Weapon Loadouts

Main article: Category:Penta Build

See the user build section for builds using this weapon.


  • Using the Zoom button when Penta is in hand will detonate any grenades launched from the user.
    • Zoom is possible only when there are no existing grenades.
    • Detonations can still be triggered while the player is performing other actions.
  • Launching a grenade is silent to enemies, though explosions are noticeable.
  • Grenades have no arming delay, and can be detonated instantly with the use of the Zoom button.
  • Grenades can be bounced around corners, off walls, and over low obstacles.
  • Grenades that bounce into enemies deal damage even when bouncing off of other enemies.
  • The Arsenal UI used to label only the damage of the grenade on impact, but now labels the Impact damage of the projectile as well as the base Blast damage (350 base).
    • 82.35% [350/(350+75)] of any elemental damage shown in the UI will be used for the AOE damage while the rest is for projectile damage.
  • Increasing the Magazine size of the weapon does not increase the 5 grenade limit you can have out.
  • The physical impact of the grenade can deal a critical hit but does not show up in the game's UI.
  • Though the grenade explosion does not destroy rockets from Bombards, impacts by the grenades from very accurate (or sometimes lucky) shots can.
  • When using Split Chamber, the second grenade is noticeable from the first (but only with Heavy Caliber at a reasonable rank), though they share the same trajectory and usually bounce the same direction too.
  • The fired grenades will freeze in water.


  • Grenades fired from the Penta are lobbed in a heavy arc, allowing the player to kill enemies hiding behind cover much more easily, as the detonation happens upon external trigger.
    • Multiple impacts dealt by the same grenade are possible.
  • Standing at a greater height allows for the grenades to be lobbed and bounce further, allows the user to see the grenade better, as well as eliminates the worry of self-damage.
  • It is not recommended to use Shred as grenades can often go through the floor on some tilesets, making it impossible to bounce every time.
  • When using the Split Chamber mod in conjunction with Heavy Caliber, the decreased accuracy puts the grenades side-by-side and you can clearly see 6 total grenades out at once. This is most likely a bug due to split chamber forcing an additional grenade to spawn on the last shot.
  • Split Chamber, under random circumstances, can fire a total of six grenades. Provided multishot works on every shot, 2 shots puts out 4 grenades, allowing you to fire a third for the 5 total limit, but with 1 extra from the multishot.
  • Modding with Speed Trigger is an efficient alternative to quickly launch up to the grenade limit.
  • Elemental mods such as Cryo Rounds and Hellfire are external from the main Blast damage, allowing the weapon to have 3 seperate elemental combinations. If one creates a Blast damage combination, it will merely add itself to the main explosion damage.
  • When using the Penta with a Waframe other then Trinity, Rhino or Frost, be extra cautious and do not attempt to use in small areas. A single fully-modded grenade can usually kill any warframe unless protected in some way.
  • Players can detonate grenades in mid-air for an 'airburst' effect, which deals headshot damage to targets below.
    • As a side-effect of targeting the 'head' hitbox with most airburst explosions, the Penta can have limited effectiveness against Corpus Crewmen (and variants thereof) due to their heavy, damage-resistant helmets.
  • The Penta is a very effective weapon when firing from a safe location on an Infested mission.
  • Default color of grenades make it hard to see once in the middle of a crowd of enemies or from them randomly bouncing around and you lose track of them. Change the energy color to something bright, and include 3 different energy color sets, one for each general kind of tile set (eg, don't use bright white for Corpus Outpost missions).
  • Be wary when installing Infected Clip, as the Toxin damage can bypass Warframe shields and deal damage directly to health.


  • Released in Update 11.3.0.
  • This is the first weapon to have the Zoom capability replaced with a different function.
  • Penta derives from the Greek prefix of "five", which makes sense as the grenade launcher composes a magazine of 5 grenades.
    • This seems to be the first Corpus weapon to be named after Greek origin instead of Latin.
  • Penta is the third weapon model that has a magazine that responds after firing. First being the Twin Gremlins, and the second is the Soma.
  • Its model is known to be a non-static model, as the upper barrel shaft shifts when reloading.
  • It seems the entire gun represents a mere skeletal structure, unlike most Corpus weaponry.
  • Increasing the magazine size actually increases the visible grenades stored in the weapon, being the first weapon with this obvious visual ammunition increase.
    • With 5 grenades in the weapon, there is a small gap between the fifth grenade and the bottom of the gun. With 6 grenades, there is no gap at all. With 8, the stack actually exceeds the bottom.
  • The Penta is the first Corpus weapon to focus on explosive weaponry, utilizing the technology on Plasma grenades through a launch system. They, however, deal blast damage, which does not fit the Corpus theme.
  • The grenades are flat and rectangular, which is odd, considering their bouncy movement.


  • Rarely a detonation will cause damage to you even if the grenade is well beyond the explosion radius. (Online issue, Fixed in patch 11.5) Not Fixed patch 11.5.3 and can kill you.
  • In its Arsenal UI, it does not display its trigger function, though it functions as Semi-Auto.
  • Occasionally, the flames emitted by the Penta can remain indefinitely if reloaded too frequently.
