The developers had announced the addition of zombies to Call Of Duty: Advanced Warfare at the last minute without specifying any further details. Now, there’s good news for the gamers as it has been revealed that they can unlock a Zombie skin for the game to use in online multiplayer. However, it is essential to complete a set amount of waves of Exo-Survival, the game’s co-op mode in order to be able to unlock the skin.
The Exo- Survival mode can be played locally, on LAN or online just like previous co-op modes. The maps are the ones from the online multiplayer, broken into four tiers. Tiers 1-3 each have four maps culminating in the last tier and map Riot. The unlocks for each tier are listed below along with their maps. Once you reach Tier 4, after round 10 there will be a zombie round and once you complete it and extract you will unlock Call Of Duty: Advanced Ware Zombie skins as well as related armor and equipment to use online in multiplayer. So it can take quite some time.
