Rockets are basic ranged weapons that can be found in any league. They point forward and shoot a rocket about every second. They do a medium amount of damage, and they can be useful if you don't have wheels.
Rockets are the first weapon you can get and use, along with blade and stinger. The ultimate version of this is the cutter rocket.
