Weapon Loadouts[edit source]

Notes[edit | edit source]

  • Detonations can be triggered while the player is performing other actions.
  • Launching a grenade is silent to enemies, though explosions are alarming.
  • 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 bounce into enemies deal damage even when bouncing off of other enemies.
    • Multiple impacts dealt by the same grenade are possible.
    • Grenades do not bounce when striking water, coming to a dead stop instead. This allows perfect aiming for setting traps
  • Increasing the Magazine size of the weapon does not increase the 5 grenade limit.

Tips[edit | edit source]

  • 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 self-damage.
  • Be extra cautious and do not attempt to use in small areas. A single grenade can usually kill any Warframe unless protected in some way.
  • Players can detonate grenades in mid-air to score headshots.
  • 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 maps.

Trivia[edit | edit source]

  • 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.
      • Interestingly, PENTA does not usually detonate upon impact or ignition, but rather needs an external explosive trigger, similar to the Penta's grenades.
  • The Penta formerly used Mod TT 20px.pngRifle Ammo Mutation instead of Mod TT 20px.pngSniper Ammo Mutation, while still using sniper ammo. This was fixed in Update 17.5.
  • The Penta is one of the weapons with a non-static model: the magazine feeds up to the gun upon firing and the slide around the barrel is pulled back during reloading.
    • While weapons like Gremlin.png Twin Gremlins and U10DesignCouncilTennoAR.png Soma also have animated magazines, the Penta and Secura Penta 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 protrude from the bottom of the weapon.
  • The Penta was the first Corpus weapon to focus on explosive weaponry, followed by the Lenz.png Lenz in Update 21.3.
  • The grenades are flat and rectangular, which is odd, considering their ability to bounce.
    • Prior to Update 23.2, the Mod TT 20px.pngTether 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.pngTether Grenades now causes the grenade to spin towards the enemy instead of staying flat.
  • Prior to Update 18.5, Mod TT 20px.pngAdhesive Blast caused grenades to explode after a set amount of time.
  • This is the first weapon to have the Zoom capability replaced with a different function pre-Update 17.0.

Bugs[edit | edit source]

  • 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.
