The Zombie Plague event was an in-game event in the computer game World of Warcraft. It ran from October 22nd to November 12th 2008. The event introduced a disease into the game that eventually turned players into zombies. Players were able to play as zombies with new abilities and limitations and they were automatically allied with all other zombies. The event was a precursor to the launch of Wrath of the Lich King, Blizzard Entertainment''s second expansion for the game. Zombie players were able to attack other non-zombie players and, by using certain abilities, transfer the disease to other players. Initially, the disease was relatively easy to get rid of and lasted 10 minutes prior to turning you into a zombie. Most players took the opportunity to turn themselves into zombies in order to experience the zombie''s abilities and have a new form of fun. As time progressed, the disease duration was reduced and the zombies became difficult to avoid.
