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

Penta is a Grenade launcher used by IconCorpusOn.png Corpus Penta Rangers. It launches ballistic grenades that can be manually detonated with Alternate Fire.


  • This weapon deals primarily DmgBlastSmall64.png Blast damage.
  • Can only have five grenades out at once.
    • Extra projectiles generated by Multishot will count towards the limit of five live grenades.
  • Grenades explode in a 4 meter radius upon impacting a surface or enemy.
    • Initial hit and explosion apply status separately.
    • Explosion inflicts self-stagger.
    • Explosion has linear damage falloff from 100% to 50% from central impact.
    • Explosion does not need direct line of sight to deal damage and will penetrate walls.
  • Can use the Penta-exclusive Mod TT 20px.png Tether Grenades and Mod TT 20px.png Napalm Grenades, as well as the launcher-exclusive mod Mod TT 20px.png Adhesive Blast.
  • Can benefit from Mod TT 20px.png Firestorm (Mod TT 20px.png Primed), Mod TT 20px.png Amalgam Furax Body Count, and Mod TT 20px.png Cautious Shot.


  • Pinpoint accuracy.
  • Grenade Impact
    • Above average disposition

  • Grenades have slow travel time and heavy arcing.
  • Grenades have a high bouncing capability which makes it hard to stack on a desired spot.
    • Can bounce off teammates or companions.
    • This can be countered with Mod TT 20px.png Adhesive Blast which will make the grenades stick to any surface.
  • Low magazine size.

  • Detonations can be triggered while the player is performing other actions.
  • The launch/flight of a grenade is silent (though the actual explosions are alarming, obviously).
  • Grenades have no arming delay, and can be detonated instantly with the use of the Secondary Fire button.
  • Grenades can be bounced around corners, off walls, and over low obstacles.
    • Grenades that continuously bounce into enemies will deal impact damage with each collision.
    • Grenades do not bounce when striking water, coming to a dead stop instead. This allows for easier setting of traps.
  • Increasing the Magazine size of the weapon does not increase the 5 grenade limit.
  • Though the grenade explosion does not destroy rockets from Bombards, impacts by the grenades from very accurate (and lucky) shots can.
  • With Multishot, the second grenade is usually indistinguishable from the first, as they follow the same trajectory simultaneously and bounce in the same direction. They can be "separated" with negative accuracy from Mod TT 20px.png Heavy Caliber at a high enough rank.


  • 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.
  • Standing at a greater height allows for the grenades to be lobbed and bounce further, allowing the user to see the grenades better, as well as eliminating the worry of stagger.
  • A maxed Mod TT 20px.png Firestorm increases the blast radius from the initial 5 meters up to 6.2 meters (6.64 with Primed Firestorm), allowing more enemies to be caught in the blast.
  • It is not recommended to use Punch Through mods as grenades can often go through the floor on some tilesets, making it impossible to bounce every time.
  • Mod TT 20px.png Split Chamber can spawn a sixth grenade provided that the multishot procs when 4 grenades are already out
    • While multishot mods are commonly considered necessary to increase damage output, due to the Penta's mechanics of careful detonation and limited grenades active at once, it's not as much of an instant damage increase as with normal weapons. It can be useful for setting up a large number of grenades faster, however.
  • Elemental mods such as Mod TT 20px.png Hellfire are external from the main Blast damage, allowing the weapon to have 3 separate elemental combinations.
  • Players can detonate grenades in mid-air to score headshots on targets below.
  • The default color of the grenades can make it hard to see in the middle of a crowd of enemies or from their bouncing. Changing energy color can help with certain tile sets (e.g. do not use bright white for Corpus Outpost missions).
  • Grenades will immediately explode when they hit Blunts, water surface, puddles from Tar-Mutalist Moa or Bulwarks.


  • Penta derives from the Greek prefix of "five", which may refer to its magazine of 5 grenades.
    • This seems to be the first Corpus weapon to be named after Greek origin instead of Latin.
    • It could also be derived from the explosive compound PENTA.
      • Notably, PENTA does not usually detonate upon impact or ignition, but rather needs an external explosive trigger, similar to the Penta's grenades.
  • The Penta (and its variants) are the first and currently only weapons for which the magazine becomes visibly larger as magazine capacity is increased. With high enough capacity the magazine will even protrude out from the bottom of the magazine feed.
  • The Penta formerly used Mod TT 20px.png Rifle Ammo Mutation instead of Mod TT 20px.png Sniper Ammo Mutation, despite still using sniper ammo. This was fixed in Update 17.5 (2015-10-01).
  • The Penta was one of the first weapons with a non-static model: The magazine feeds up to the gun upon firing and the slide around the barrel are pulled back during reloading actions.
  • The Penta was the first Corpus weapon to focus on explosive weaponry, followed by the Lenz.png Lenz in Update 21.3 (2017-08-02).
  • The grenades are flat and rectangular, which is odd, considering their ability to bounce.
    • Prior to Update 23.2 (2018-08-02), the Mod TT 20px.png Tether Grenades augment changed the grenade model to be a short cylinder with concave ends. It still used the default grenade texture, which looked strange but was normally obscured by the grenades's blue glow.
    • Mod TT 20px.png Tether Grenades now causes the grenade to spin towards the enemy instead of staying flat.
  • Prior to Update 18.5 (2016-03-04), Mod TT 20px.png Adhesive Blast caused grenades to explode after a set amount of time.
  • This was the first weapon to have the Zoom capability replaced with a different function pre-Update 17.0 (2015-07-31).
  • The Arsenal interface used to label only the damage of the grenade projectile impact, but now labels the DmgImpactSmall64.png Impact damage of the projectile as well as the base DmgBlastSmall64.png Blast damage seperately (350 base).


  • In its Arsenal UI, it does not display its trigger function, though it functions as Semi-Auto, possibly because it deals damage on impact, unlike other Active trigger weapons.


Penta Skins Edit

Patch History[]

Hotfix 27.3.16 (2020-04-22)

Hotfix 27.2.2 (2020-03-06)
Reduced the following AoE weapons Radial Damage Falloff from central impact that were all previously 90%:

  • Penta: 50%

Update 27.2 (2020-03-05)

Self Damage Changes

We are getting rid of Self Damage and replacing it with something else: instead of Self Damage, it’s now ‘Stagger’. This change completely removes the chance of killing yourself, and instead now creates scenarios where you will interrupt yourself - or ‘Stagger’ - to varying degrees if you aren’t careful.

The degrees of Self-Interrupt start with a small stumble all the way to full knockdown depending on how close you are to the center of explosion. Any Mods referring to Self Damage will be converted to acknowledge Stagger.

With this Self-Interrupt system, we have added dozens of new recovery animations that harness a ninja-like recovery experience. By pressing ‘Jump’ at the correct time, you can execute a ninja-skill-based knockdown recovery to ALL in-game knockdowns. This ninja recovery window is indicated by a glowing FX on your Warframe.

In the original Dev Workshop, we said:
As a result of this overall systemic change, Weapons with Stagger will be getting approximately a 20% buff in Damage, with any weapons with AOE receiving a 50% Radial Damage Falloff from central impact.

This is no longer accurate after continued testing. What we are doing now is:

No damage buffs have been added, but any weapons with AOE are receiving ~20% increase in Radius. Additionally, AOE weapons are receiving a 90% Radial Damage Falloff from central impact. This means on the very outer section of the explosion Radius 10% of the Damage will be dealt. Tactics will be deadly - aim true, Tenno.

Why: Several players brought up the history of the Tonkor and we want to make sure we ship this change in a place that’s conservative in its starting point from a balance perspective. The complete removal of Self Damage does change the pace of destruction with some of the game’s most powerful weapons, so we want to make sure we can iterate upwardly instead of releasing a bonanza of explosions with no other choices.
