Shoots sharks. Really.

This gun, a Calx original, fires homing sharks. This would never function under normal circumstances, but the Gungeon respects the pure audacity of its existence.

Compressed Air Tank is a gun that fires sharks that swim around the room, seeking enemies and biting them, dealing a large amount of damage. Water is created wherever the sharks have been.


  • Synergy.png Smile, you son of a... - If the player has M1, Compressed Air Tank's sharks will explode upon biting an enemy. These explosions will hurt the player.
  • Despite the shot being chargeable, the shark will fire even if the trigger is tapped.
  • The shark fins will deal contact damage, like other wandering bullets.
  • Battery Bullets can be extremely effective with this gun, as the water its projectiles leave behind will be electrocuted.
  • If a Bloodbulon is hit with the shark, it will not die immediately, and upon dying, it will not release bullets.
  • Pinheads and Nitra will not explode when killed by a shark.
  • Blobulons, Poisbulons and King Bullats will split when killed by a shark.
  • Firing sharks over the lava in the Forge will permanently make it so the player cannot be burned by it, even once the water goes away.
  • If used with Backup Gun, two sharks will be fired at once, and will independently home in on targets.
  • The sharks will not cross pits, unless battling a boss that includes a pit in their arena, such as Gatling Gull, Fuselier, Agunim, or the High Dragun.
  • Works especially well with Snowballets, since the sharks' tendency to wander feeds into the effect of the Snowballets.
  • Although this gun fires water, it cannot be used to get the item from the Black Market.


  • This weapon and its unique ability are a reference to the 1975 movie Jaws. It also makes a brief sound resembling the Jaws theme whenever it fires. It could also be a reference to the Sharknado movie series because of the reference to "pure audacity of its existence".
  • This weapon behaviour is similar to the Land Shark Gun from the game Armed and Dangerous.
  • This weapon appears in the prequel comic.
  • The "Smile you son of a..." synergy is a reference to Martin Brody's final line in Jaws before killing the shark. Brody wields a M1 and shoots an air tank in its mouth.
  • This weapon could also be a reference to the Dungeons & Dragons "Bulette" (sic) monster, which is also called a "landshark" and shares its shark-like nature with the weapon's projectiles.
