Crawler Cannon

A rocket propelled grenade-type weapon with Crawlers used as the ammo (although this is not shared with the individual Crawlers that are used as hand grenades). Primary fire shoots in a straight line to the target, exploding and causing damage in a large radius. Secondary fire vaporizes the Crawler into a lingering cloud of acid, effectively creating a shield in front of Tommy which dissolves any projectiles that come into contact with it.
