In Battletoads in Battlemaniacs (USA), you play as an alien creature that must battle your way through a series of enemies in order to reach the exit. The enemies vary in strength, but they all have one common goal: to block your progress. To do this, they will use their own creatures as shields, and you must use your own creatures to destroy them. The game is highly randomized, so you never know what will happen next. The environments are also highly customizable, so you can make your creature look almost any way you want.
