Chamber Gun

Product of EnvironmentSemiautomatic

Transforms based on Chamber. This gun uses an advanced shape-memory alloy. When exposed to different environmental stimuli it reacts with the salts in Gungeoneer’s bodies and transforms into a location-specific gun. Master rounds can also influence the shape of this curious weapon.

Notes

  • In the Keep of the Lead Lord , the Chamber Gun is a single target, semi-automatic gun.
  • In the Oubliette , the Chamber Gun fires poison skulls.
  • In the Gungeon Proper , the Chamber Gun is a shotgun that is somewhat similar to [The MembraneThe Membrane] .
  • In the Abbey of the True Gun , the Chamber Gun is a piercing crossbow.
  • In the Black Powder Mine , the Chamber Gun is a melee-range, high damage drill. Having [Flak BulletsFlak Bullets] equipped, this form will fire small, spark-like bullets in front of it, with significant damage output. This is a good combination with [Orbital BulletsOrbital Bullets] .
  • In the Resourceful Rat's Lair , the Chamber Gun is a rocket launcher which fires cheese wheels that encheese enemies, similar to those fired by the [ElimentalerElimentaler] .
  • In the Hollow , the Chamber Gun is a combination of [GlacierGlacier] and [The ExoticThe Exotic] ; it fires an ice cube projectile that bounces off walls and enemies, leaves a trail of water, and eventually bursts into several homing rockets.
  • In the R&G Dept. , the Chamber Gun is a pencil which functions similarly to the [Wood BeamWood Beam] , except that when you reload it, it flips to the other side (Pencil-> Eraser -> Pencil).
  • In the Forge , the Chamber Gun is a beam weapon that shoots 2 homing beams of lava in a V-pattern.
  • In Bullet Hell , the Chamber Gun is a homing chain beam similar to the [Raiden CoilRaiden Coil] , hitting all visible enemies at once for high damage.
  • All modes share the same ammo pool. Firing a shot in one mode reduces the ammo of the other modes by a proportional amount. For example, firing one shot in its Hollow mode uses up 10 shots of the base mode, because the base mode has 10 times the max ammo.
  • The Chamber Gun is one of the three weapons in the NONE gun class that can be obtained in normal play, the others being the [SlingerSlinger] and the [Kruller GlaiveKruller Glaive] .
  • If the player has [Chance BulletsChance Bullets] and does not switch to the Chamber Gun from a floor that does not have a [Master RoundMaster Round] (such as the Oubliette , Abbey of the True Gun , Resourceful Rat's Lair , or the R&G Dept. ), other guns have a chance to shoot bullets from that firing mode.
