About Fatal Theory
Fatal Theory is a beat-'em-up in which you fight through hordes of enemies and take your city back from the forces of hell. You play as Nick Mayhem, whose night is interrupted by news that the dead are walking the streets. Armed with a baseball bat, Nick faces demon generals and their armies, guided by a judgemental talking sword.
Story
Nick fights his way toward the head of the forces attacking the city. Along the way, he meets a bizarre cast of characters and battles 9 bosses, slaying most of those he encounters. The illustrated story uses comic-book-style art and dark humor, and follows Nick as he tries to save his city and find love during the apocalypse.
Combat and upgrades
You fight large waves of enemies, string together combos and build a damage multiplier. Filling the rage bar lets you perform special attacks using button combinations. Completing levels earns cash, which you can spend at the shop to improve Nick’s stats. You can also unlock 6 weapons and level them up to gain new special attacks.
