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.

Each Master RoundMaster Round the player carries permanently unlocks the mode of its respective floor. Reloading the Chamber Gun with a full magazine cycles through the unlocked modes. This synergy does not work with Lich's Eye BulletsLich's Eye Bullets .

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.
