Having 'launcher' for both a type of weapon and the name of a shot is definitely confusing at times. When telling people about ''Berserk Launcher'' I often have to specify ''not the Shot, Berserk Launcher, but the Launcher, ES Launcher with Berserk".
Launchers are 2 types of weapons also because Bazookas are a sub-category within Launchers (non-combo launchers), not to be confused with ES Bazooka/Inferno Bazooka which are both actually shots.
Good Job Sega.
