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. It is selected as an ammunition type versus the frag grenade via a toggle key or button ("G" by default for keyboards).

Trivia

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