Infection

Looking for the Flood Infection Form?

Infection is a multiplayer gametype in Halo 3. It is the official Zombie mode after its popularity as a custom game in Halo 2.

Objectives
The object of the game is for the Humans and Sangheili to stay alive as long as possible while the zombies try kill to every living player. The number of players starting out as Zombies ("Alpha Zombies") can be changed in the options and are selected at random from the start. When a zombie kills a "living" player, they are "infected" and thus become a zombie. When there is just one living Human or Sangheili left, he/she is declared "Last Man Standing". The first Alpha Zombie is determined at random at the beginning of the game. In all subsequent rounds the Alpha Zombie is the player who scored the most points in the previous round.



One way Infection is commonly played is that players will make custom maps with Forge where the living have a strong point equipped with weapons, grenades, equipment and vehicles to defend against the zombies.

An option and popular way to play of infection on Snowbound is where the humans try to defend the rock that they are at while fending of zombies. It works best if the ratio of the zombies to humans is 1:3.

Yet another tactic that the "living" use is called "baiting". The human players gather in a small, confined space; preferably one with only one opening. Whenever the zombies' attacks lull, the humans send out a freelancer, known simply as "bait". The "bait" will attempt to lure the zombies closer to the human stronghold, where an unhappy death awaits any undead.

Halloween
On October 31, 2007, a specialized Halloween matchmaking playlist was available, which played this game mode with precisely 13 players (it being an "unlucky" number).

Double EXP Weekend
On April 10th, 2008, the playlist came back for a Double EXP Weekend, also starting with exactly 13 players.
