Played the game back in the old days when i still had a windows ME computer. There's a lot of interesting aspects to the gameplay such as spine-breaking moves - quite literally, you can extract the spines out of enemies and use them to club enemies and throw it. You can even pick up car engines and throw them too, they all do the same damage. Upgrading your character can be done by eating special food, such as subways subs, CD ROMS, Vinyl records and floppy disks. Late-game, you can summon an uzi to help you eliminate the devil. But first, you need to dance with the zombies.
After fighting the zombies on the dancefloor, there are several other stages, the subway features the vampires, the tombs and beach feature the mummies, and the pirate ships, well, pirates. Then there are the cemetary with more zombies and vampires, and then hell where you fight demons. There may be more sections I may have missed. The game's kinda open world where you can do miscellaneous things such as play basketball with a friendly zombie, and the gameplay are basically 2D background fights in a 2.5 dimension combat space (vertical/horizontal axis + jumping). There are combos, but that's left up to you to figure out how to do them. Some such as ripping arms off the enemy require you to unlock them however and summoning guns requires mana or something. I dunno, it's been like 20 years since i played this game. I'm trying to find it again.
