Jim Power is a shoot'em up game similar to Mega Man, Turrican, Contra and the like.
There is a bit of a split story of the game, as two different versions were made that share the same enemies, bosses, level designs, and soundtrack.
In Jim Power Mutant Planet, Jim Power is sort of John MClane type detective, which is called in to rescue the president's daughter who has been captured by an evil monster and taken to Mutant Planet.
In Jim Power in Lost Dimension, which portrays Jim Power as an Intergalactic Soldier, Jim travels to a 5th dimension to stop an evil monster called Vaprak from invading and destroying earth.
The Game Soundtrack features rocking music composed by Chris Huelsbeck (Turrican, Gemx, Apidya, Tunnel V1)
