On the other side of an interdimensional portal lies the game world of Monster Realm, a place where monsters battle humans, where souls are held captive, and where Tom Hock, also known as, Combat Boy narrowly escaped. Now, he’s home and feeling safe—big mistake.
Tom’s brother, Joey wants to play. He paralyzes Tom with a poison dart and reassembles the fabled monster token to start the game which spreads across San Diego. Now, Joey is the boss. He makes the rules and designs the monsters, but what kind of game will a scatterbrained teen create?
Tom charges through the game’s wacky, twisted, and hazardous levels, alongside a band of misfit gamers and vows to sacrifice his soul to save San Diego. But is that enough to beat the game, and stop Joey from unleashing his master plan of ruling as Lord of Monster Realm forever?
