This article describes a feature in the first Apocalypse Rising
"Awarded to those who kill at least 50 zombies, and survive for 3 days. You must accomplish this all in one life, and you cannot earn this badge in a VIP server."
- Using melee weapons against zombies can conserve ammo.
- For more zombie kills, go into more heavily populated areas, such as Union Square.
- Silenced weapons should be used for zombie killing, so that you don't attract the whole horde (or other players).
- Always be on the move, to avoid other players and keep your killing consistent.
- Be stealthy. Running into bandits could be a problem for your task.
