The Cryo Cannon was a man-portable scientific instrument that dispensed an endothermic chemical in a gaseous form. During the Swarm War, it was repurposed as a weapon. After only seconds of direct, continuous exposure to the Cryo Cannon's blast, an organic target was frozen solid and could be shattered into pieces with a blunt strike. Larger targets required longer exposure to freeze and multiple strikes to shatter.

Cryo Cannons were found and used extensively in Mount Kadar Laboratory, where an uprising led to a system failsafe that put the entire area in a deep freeze through its multiple automated Cryo Cannon turrets.


The Cryo Cannon is essentially a reverse Scorcher Flamethrower. Like the Scorcher, the Cryo Cannon is a close range spread weapon that could affect multiple enemies at once. Unlike the Scorcher, the Cryo Cannon does not instantly kill or down an enemy. Rather, it puts them in a vulnerable 'freeze' in which they could be shattered by a bullet or a melee attack. If the frozen target is left awhile, than he/she would unfreeze and escape shattering.

Due to its short range and unique nature. Cryo Cannons are effective as support weapons. As assault weapons however, Cryo Cannon users are vulnerable. As a heavy weapon, Cryo Cannon encumbers a user's speed and the need to shatter enemies with extremely close melee attacks makes these weapons unviable in firefights, in contrast to the more smaller and nimbler Scorcher.


The player kicks the enemy on his/her side before lodging the Cryo Cannon's barrel within their stomach, lifts them up and fires the Cryo Cannon's cryogenic liquid. This freezes the enemy before the player slams them down on the ground, shattering them.

Behind the scenes[]

  • The weapon is the opposite of the Scorcher Flamethrower, and is its spiritual successor.
  • It is unknown what type of liquid the Cryo Cannon uses, although the most likely answer is liquid nitrogen.
  • The Cryo Cannon's execution doesn't expend ammunition when the weapon is fired.
