The latest entry in the Call of Duty series, Black Ops 4, marks a major departure in some ways. It has no traditional single-player campaign and introduces a battle royale mode, Blackout, to the mix. But being developed by Treyarch, it does include the signature Zombies mode.
This cooperative mode again pits a team of players against waves of zombies, though it comes with two different storylines. Aether continues the story established in previous games, while Chaos offers up one featuring new characters Scarlett, Stanton, Diego, and Bruno. The video above showcases the special Rush mode, which does away with the typical progression seen in Zombies and allows you to obtain weapons for free and unlocks all doors for you.
