Ice bomb

The ice bomb is one of the auxillary weapons in Doom Eternal. Fired from the shoulder-mounted launcher of the Praetor suit, the ice bomb is a projectile that douses the target in "freezing gasses", causing a flash-freeze. The frozen enemy is then left immobile and helpless, and shatters after enough damage has been inflicted upon them.

Trivia

 * Interesingly, it has been observed that airborne demons like pain elemental can remain suspended above the ground even when frozen.
