Like the Survival mode in Modern Warfare, Call of Duty: Black Ops Cold War will feature a timed exclusive mode for the PS4 & PS5. Onslaught is a wave-based two-player co-op zombie mode that takes place on the multiplayer maps in Black Ops Cold War.
The new mode will be exclusive to the PlayStation platform for a whole year before it hits Xbox Series X|S, Xbox One and PC on November 1, 2021. Just before the next Call of Duty will likely release!
Based on this initial reveal, Onslaught seems to share many similarities with its predecessor PlayStation exclusive mode survival. As the rounds progress, the zombie enemies will get tougher with surges including “elite enemies, more powerful adversaries compared to the regular zombified masses”.
Upon the completion of a game of Onslaught, players will earn either a bronze, silver, or gold ranking. This is based on the number of elite zombies you and your fellow teammate have taken down.
These ranks are important for out of Onslaught as players can unlock rewards across the two most popular modes in Black Ops Cold War Multiplayer and Zombies.
