343 Industries has revealed that the fan favourite Infection game mode from Halo 3 and Halo: Reach is coming to Halo 5: Guardians.
Infection is a zombie-themed multiplayer mode where one or more players start out as a "zombie" and their objective is to kill other players and infect them in the process. Infected players will then become "zombies" and have to eliminate the remaining players. When there's only one player "alive" he/she is declared "Last Man Standing".
