Call of Duty: Black Ops Cold War will offer an exclusive Zombie mode to PS4 and PS5 players for one year. Called Zombies Onslaught, the new two-player co-op features waves of increasingly difficult zombie hordes spawning and attacking. The goal is to kill the undead and survive.

According to PlayStation's blog, the Zombie Onslaught mode will deploy you and another player to locations from various multiplayer maps. Players will have the same custom loadouts as they do in traditional Zombies and Multiplayer modes.

When arriving on the map, the players' range of movements will be restricted to a smaller area by a Dark Aether orb. Zombies will then start spawning and attacking, and each subsequent wave of the undead will be harder to kill. After defeating enough zombies, the Orb will shift locations. If you're inside the Orb, you will be protected from Dark Aether damage.
