Call of Duty: Vanguard 's campaign mode might not have set the world on fire, but the multiplayer modes are still going strong. Players who haven't jumped in yet now have a great chance to do so, as both the cooperative Zombies and competitive Multiplayer modes are free to download and play from July 20-26. What's more, July 26 will see the "Mercenaries of Fortune" update arrive (though without a new Zombies map).

For cooperatively-minded folks like us, Zombies mode is usually the highlight of any Call of Duty game. That certainly holds true for Call of Duty: Vanguard, which has the series' best Zombies mode in recent memory. Things got even better this week thanks to the deployment of "Shi No Numa," Vanguard's third Zombies map (and a returning favorite from past games). We spent a couple of hours in the deadly swamp-based map and had a bloody good time.

The latest Zombies map to be added to Call of Duty: Black Ops Cold War is called 'Mauer der Toten,' meaning "Wall of the Dead." The Black Ops Cold War Zombies maps are surprisingly story-heavy, and this one sees the members of peacekeeping force Requiem forced to build a warhead to close the Dark Aether portal that was opened in Berlin by traitorous scientist Aleksandra Valentina. We played several co-op games on 'Mauer der Toten,' and we even found out how to unlock the robot, Klaus.

Call of Duty: Black Ops Cold War is going to receive a major update this week on January 14th, as the "mid-season update" goes live with the game across all platforms. While most of the changes are focused on the game's PvP modes with new maps, weapons, and playlists there is some good stuff for co-op fans.
