Call of Duty is a big deal every year, but perhaps never as much as this one, the first year that a new CoD will launch on Game Pass. Today, Microsoft showed off Call of Duty: Black Ops 6 at the Xbox Games Showcase, revealing lots of cool gameplay footage and details. We also learned how the cooperative Zombies mode will work - always the most important information for co-op enthusiasts like us.

This year's Xbox Games Showcase was light on cooperative content; Microsoft didn't seem to focus on co-op features in any of the game reveals. Still, the showcase did show some genuinely hot games, so we can't complain too much. Some of the games shown might even end up featuring co-op that hasn't been announced yet. In the meantime, let's look at all of the games that were announced and which ones we know will have co-op.

We don't know yet whether this year's Call of Duty (Black Ops 6) will feature a co-op mode, but they usually do. Microsoft and Activision have announced that the game will be revealed to the world on June 9, so we're hoping to find out some co-op details soon. What's more, Microsoft also announced today that Call of Duty: Black Ops 6 will be coming to Xbox Game Pass at launch. That's a big get for Xbox, and surely one of the reasons that Microsoft bought Activision in the first place.

Call of Duty: Modern Warfare III is the latest game in Activision's long-running military FPS series. Unfortunately, some Xbox owners have run into an annoying "disc read" error when they try to play - even if they own the digital version of the game. Not to worry, though! The fix is relatively simple, and we'll show you how.

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.

For co-op enthusiasts, Zombies mode is always a highlight of Call of Duty games. The Zombies mode in Call of Duty: Black Ops Cold War has slowly been telling the intricate story of Requiem, a CIA faction dedicated to sealing dimensional breaches and saving the world from a zombie apocalypse. That narrative continues with the impending arrival ...

If you wanted to see what Call of Duty offers for co-op players, now is a good time to dive into the Call of Duty: Black Ops Cold War's zombies mode, which is free from January 14th through the 21st.
