A rocket launcher that fires Crawler-filled spheres as rockets. Note, that gun ammunition is different from usual Crawlers (used as hand grenades) and not shared.
Primary fire shoots in a straight line, immediately exploding on impact and causing very high direct hit damage to target, as well as high collateral damage around the explosion.
Secondary fire vaporizes the Crawler into a lingering cloud of protective absorbing acid, that effectively shields its user from any incoming projectiles.
Crawler Cannon is a versatile weapon that can be used for both offense and defense. During combat is advised to first deploy the gas shield in order to protect itself from oncoming damage and then use the primary fire while hiding behind the shield. The weapon is also good for crowd control.
