Remember virus from TimeSplitters? My friends and I were playing Halo 2 last night and we would do something like virus where one guy would have the beaster sword and everyone else non-swords. As soon as you get beat down from the beaster sword you turn into a zombie too. The last person to die is then the first zombie. Green team is the zombie team. Kinda fun, just thought I'd let you guys in to try it out.
