Zombie Mayhem is a supernatural action console video-game in which the player has to defeat hordes of zombies in order to level up. Scores are given depending on how many zombies the player slays. The game has both a single-player and competitive multi-player mode and allows the player character to be either a male or female avatar.
As of Kim and Ron's sophomore year there are three iterations of the game released thus far. While Ron argues that the second installment is superior, Felix prefers the third - part of his justification being that Zombie Mayhem 2 doesn't include flamethrowers.
Ron, Felix, and eventually an initially jealous Kim, attend an event called 'Zomba-Palooza' in which the game is to be played for twenty-four hours in order to provide research on repetitive stress injuries. Unfortunately the event is interrupted by Motor Ed .
- Zombie Mayhem could potentially be based loosely on, or a reference to, the Resident Evil games (verification still needed).
