Spelunky Wiki

The Plasma Cannon is a Weapon in Spelunky 2.

The simplest way to obtain the Plasma Cannon is by stealing it from its guaranteed spawn in the Mothership, using bombs to remove the Forcefields protecting it or killing Lahamu to deactivate them.

Plasma Cannons can also be found in shops owned by Tun, Ghists, or Cavemen, and there is also an extraordinarily rare 1 in 10,000 (0.01%) chance of finding one in a Crate.


The Plasma Cannon, as found in the Mothership.

The Plasma Cannon is the most powerful weapon in the game, capable of demolishing entire levels and turning most common enemies into smoldering chunks.

When used, Plasma Cannons fire a fast moving ball of plasma that explodes on contact with the same radius of a bomb. The projectile itself deals 10 contact damage as well as 10 damage + 1 fire damage from the resultant explosion, totaling up to 21 damage in a single shot.

Plasma Cannon projectiles may be reflected by Forcefields, Robots, Metal Shields, Olmec, or Olmites wearing golden masks, sending the projectile back at the user.

Firing a Plasma Cannon launches the user an entire four tiles back with its recoil. This recoil is strong enough to launch the player off ropes, ladders, and even from the backs of Mounts.

After being fired, Plasma Cannons can be fired again after 2.48 seconds. If used in conjunction with a Powerpack (2), Plasma Cannons will instead be able to fire after 1.23 seconds of recharging, and launch the user back only two tiles (none if they are riding a mount) after firing, massively increasing combat potential.

While not held by a user, Plasma Cannons explode if crushed or from making contact with lava. This explosion has the same potency as that of a bomb upgraded by a Powerpack, destroying up to three tiles in the cardinal directions.


The Plasma Cannon's massive capabilities for destruction make it an incredibly valuable tool to the player, allowing them to destroy Traps and enemies with ease. This is particularly the case in high score runs, where it can uncover massive quantities of treasure from the ground at little cost.

  • With both its explosive capabilities and excessive recoil, the Plasma Cannon is as much of a threat to the user as it is to enemies. An incautious Spelunker can easily blow themselves up with the projectile or lurched back into a dangerous position with the recoil.
    • The ideal condition for shooting a Plasma Cannon is against a wall and at least 2 tiles away from the desired target before firing in order to minimize risk.
  • One should be vigilant of forcefields, robots, and other hazards that may reflect the Plasma Cannon's projectile back at them, which would likely kill them instantly or put them in a dangerous situation.
  • The Cannon's projectile can and will hit corpses in its line of fire; the user should account for the bodies of enemies before firing.
