Living Dead

Living Dead is a Halo 3 and Halo: Reach Matchmaking playlist that features Infection games involving zombies. The playlist was first available on October 31st, 2007 at 12:01 AM (Pacific Time) until November 1st, 2007 at 3:00 AM to coincidence with the holiday Halloween. Since then, the playlist returned several times as a Double EXP Weekend playlist due to popular demand, either ranked (at the Halloween weekends) or social (during the rest of the year). The playlist is free for all (FFA) and has a maximum number of players per game of 13. Many features of the playlist, including the maximum lobby size and the required and optional maps have changed since its first availability. In Halo: Reach, this playlist is permanent. Originally Infection was only playable in matchmaking via Rumble Pit. As of the October 19 update, it has gotten its own playlist.

Trivia

 * Infected Manor and Spooky House were the only maps to be designed by someone other than Bungie to be made on the playlist.
 * The variant name of Last Resort, Zomzibar, is similar to the name Zanzibar. This is clever as Last Resort is a remake of the Halo 2 map Zanzibar.
 * On Thursday, April 23, 2009, Bungie limited the party size of Living Dead to 1, and, being a social playlist, is the only recorded social playlist in Halo history to have a party limit of 1. Many claimed that this is made because of the Zombie Achievements, and some claimed that it was made to prevent boosting, but other Living Dead playlists after that were set to the maximum size of 13 again.
 * This is the Double Exp event with the most capacity of players.
