The Heal Cannon is an unlockable weapon in the game Shadow the Hedgehog. Unlike any other weapon, this weapon heals instead of destroys, similar to Heal Unit, except it can be fired multiple times. By firing this at any GUN Soldier, they will no longer shoot Shadow and instead salute him. This does not affect the Black Aliens however.
The blue "drip" illustration printed on the gun could be based on the "Damage Recover" power-up, even though the item restored vehicles, not people.
How to Obtain
The player must first complete Final Haunt in story mode to get this weapon. To get the upgraded version, one must complete it again with the opposite mission.
