Save One Bullet
Save One Bullet is a variation of Halo 3's Infection multiplayer game type. It is essentially the same as normal Infection, except that no weapons spawn on the map, so the human and Elite team must be careful to conserve ammunition. It is advised to take the dead players weapons (human or zombie) when possible, and to use head shots.
Zombies have full shields and a longer jumping distance. They spawn with the Energy Sword. Humans have limited ammo, and spawn with the pistol and shotgun.
