The second Simpsons-licensed game on NES has Bart Simpson transforming into Bartman to rescue his favorite comic book hero, Radioactive Man, from the Limbo Zone. The action takes place from a side-scrolling perspective as you guide Bartman across a mix of traditional platform stages as well as some flying and swimming sequences. Avoid the likes of rats, bats, gargoyles, and crabs while exploring a junkyard, sewer, cavern, and other underground environments. Collect power-ups in the form of lightning, tornados, snowflakes, and radiation to fire eye beams, gain temporary invincibility, earn extra health, and more. Battle a total of four bosses in your quest to save Radioactive Man and win the game.
