Smoke Bomb

The Smoke Bomb is an item in Check It Containment Facility. It can be used as cover for getting away or to make it harder for enemies to fight you.

In-game
The smoke bomb appears as a smoke grenade, specifically the M18 Smoke. When used, it will begin to emit a cloud of gray smoke that will gradually get larger. After the smoke goes away, the bomb will disappear as well.

In older versions of the game, smoke bombs used by Default Occult Coalition members would emit blue smoke rather than gray. This was possibly because bullets from a DOC G36C shot blue projectiles, meaning the other weapons used would also use blue particles (this was not the case with the P99 and Baton because the baton was blue to begin with and why would the P99 fire blue bullets).
