Zombie Annihilation

Zombie Team Annihilation is a zombie player vs player mode in Counter-Strike Online.

Overview
Zombie Team Annihilation is mode whereby humans and zombies face each other until one side cannot continue. Although it is similar to Zombie Infection modes, humans will get killed instead of infected once a zombie attacks them. In consequence, half of the players are infected already, but unable to see, move nor attack. Each time a round starts, it will be given 20 seconds for humans to get cover, after the time passes the zombies will be free to move and attack them.

 * Humans are instantly killed, not infected.
 * Killed players do not respawn.
 * Each round both teams are scrambled.
 * There are no Supply boxes.
