The Wrist Rocket is the secondary weapon used by a some of the units in-game. It is a rocket fired obviously from the wrist of the unit. It flies fairly slow, so you'll generally have to aim ahead of moving targets. There are a very limited number of rockets, so conserving them for more important targets is intelligent, as if you hit, a large amount damage will be taken. Wrist rockets can be rather difficult to use effectively, and involve a lot of luck. Save them for heroes (beware of lightsaber deflection) and powerful units.
