Trouble Shooter, known in Japan as Battle Mania (バトルマニア), is a scrolling shooter developed and published by Vic Tokai for the Mega Drive/Genesis in 1991. The game was given a very distinct theme of self-parody between the enemies, story and dialogue. A sequel titled Battle Mania Daiginjō (バトルマニア 大吟醸) was also released for the Mega Drive in Japan and Korea only.
