Invasion of the Zombie Monsters is a B-Movie styled platformer for MSX. You take control of Ned, a geek trying to save his girlfriend from a giant demon terrorizing the city. This game was designed to be a throwback to games like Legend of Hero Tonma and Ghouls 'n Ghosts.
Ignoring the game's difficulty, the author, NitroGenesis, shreds through hordes of zombies and gets the girl in less than 5 minutes by manipulating bosses and abusing hitboxes.
