Zombies

Were you looking for The Flood, a zombie like species inhabiting the Halos or Infection, a multiplayer gametype in Halo 3?

Zombie (or Zombies, Pandemic, and Dawn of The Dead) is a player-created game variant originating in Halo 2. It's roots are now untracable, and has become so popular that it has been translated into Halo 3 as Infection, with a few minor edits and many more custom game tools. The basic rules involve two teams: a small starting green team and a relatively large red team. There are no shields; red sports Shotguns and Pistols and green (the zombies) sports Energy Swords. Whenever a red team member is killed, they must switch to green team. The ultimate goal is to last as long as possible without getting killed by the Zombies, and becoming one themselves. There is also another version of this game based on the original called "Resident Evil". Instead of starting with Swords and magnums you start with just a sword. However, there are human weapons on the map. These weapons have no respawn so the players have to save their ammo. The humans have 1 hour to survive. This game is often played on Headlong, Turf, and Terminal because they resemble cities. This game was created by FaTaL DaRKN3Ss.
