Mazin Saga: Mutant Fighter (known as Mazin Wars in PAL region) is a video game for the Sega Mega Drive. It is a beat em'up/versus fighting game based on the MazinSaga manga by Go Nagai, which was in turn a spin-off of Nagai's original Mazinger Z. As Mazinger Z, the player must fight mutants and robots. Levels are split into four sections the first three see a human sized Mazinger-Z in a side scrolling beat em up and the fourth sees Mazinger Z as a giant robot to battle the boss of that level in a one on one fighting game style battle. The game was known for its insane difficulty and over powered bosses. Even if the player manages to finish the game the Earth is left in ruins and the human race must flee to Mars where the Bio Beast army attacks again. This story arc plays out during the game's ending and might have been intended for a never released sequel.
