The Black Box is a community-created primary weapon for the Soldier. It is a black, rectangular rocket launcher with rounded edges, sporting two dark grey fastening bands near the front end and case coverings hanging open at both ends of the weapon. The rear case covering swings while the weapon is in use.For every successful hit with the Black Box, the Soldier is awarded health based on how much damage is dealt (up to 20 health for attacks over 90 damage). Hitting multiple enemies with a single rocket uses the total damage that rocket deals to calculate health gain. Health gained through Black Box hits cannot grant overheal. The Soldier does not receive health if the target is invulnerable to damage, such as a Scout under the effects of [url=https://wiki.teamfortress.com/wiki/Bonk!_Atomic_Punch]Bonk! Atomic Punch[/url]; however, health is still awarded if the target is a cloaked or disguised Spy. A successful hit does not remove the effects of fire, bleeding, Jarate, or Mad Milk on the player. Health gained is shown on the HUD.Compared to the Rocket Launcher, its clip size is one rocket smaller. This makes the Black Box weaker in sustained firefights, as the user needs to pause to reload more frequently. Projectiles fired from the Black Box have the same speed as one from the Rocket Launcher, at 1100 Hammer units per second (roughly 76 km/h or 47 mph).Should a Pyro successfully reflect a Black Box rocket in such a way that it damages an enemy, the health bonus is given to the Pyro.The kill icon for the Black Box was contributed by Psyke .
