What Call of Duty Games Are Free on Xbox One?

The main Call of Duty game available for free on Xbox One is Call of Duty: Warzone. As a standalone, free-to-play battle royale experience, Warzone can be downloaded and played without paying anything.

Occasionally there are also limited-time events that make other Call of Duty games free for a short period, like multiplayer access for Modern Warfare II and Vanguard. But Warzone is the only permanently free option.

In this comprehensive guide, I‘ll give you all the details on Warzone and other ways to enjoy Call of Duty for free if you‘re an Xbox One owner. I‘ve been playing COD games for over a decade, and as a bargain hunter I love maximizing free perks and giveaways. So let me walk you through everything you need to know to get your money‘s worth.

An Overview of Warzone – The Flagship Free COD Title

Warzone originally released alongside Call of Duty: Modern Warfare in March 2020 as a free complement to the paid multiplayer experience. It quickly became a stand-alone sensation, with over 100 million players in the first year.

As a free-to-play battle royale game, Warzone competes with titles like Fortnite and Apex Legends. Matches feature 150 players fighting to be the last team standing on a massive map based on real-world locations.

One of Warzone‘s biggest innovations was introducing Call of Duty‘s signature weaponry and mechanics into the battle royale format. You can customize loadouts with guns, perks, and equipment from the full Modern Warfare experience.

Here are some key stats on Warzone as of its 2.0 update in November 2022:

  • Over 125 million total players
  • Peak of over 6 million concurrent players
  • 1.2 billion hours played in first year
  • Matches reach up to 150 players
  • Features two large maps – Verdansk and Caldera
  • Crossplay and cross-progression on Xbox One, PS4, PS5, and PC

As a free-to-play game, Warzone monetizes through optional "battle passes" and cosmetic microtransactions. But all gear and abilities with gameplay impact are 100% earnable for free.

With frequent content updates and events, Warzone always gives you something new to experience at no cost. It‘s the king when it comes to free COD action.

Accessing Limited-Time Free Events

Now, Warzone is always free, but Call of Duty publishers Activision also provide limited-time free access to premium titles around major events and updates.

For example, a Free Access Multiplayer event for Modern Warfare II is taking place from March 16-20, 2023. During this period, all Xbox owners can install a free version of MWII from the Xbox Store and experience all maps and modes at no cost.

Your progression like weapon unlocks will carry over if you choose to purchase the full game later. So these events are a nice free trial.

Similar free access periods have happened in the past for titles like Vanguard and Black Ops Cold War, usually coinciding with a big seasonal update.

I‘d recommend following Call of Duty news sites like CharlieIntel to stay on top of when these free events are scheduled. And don‘t forget to download the free version during the specified dates to take advantage.

Free access events typically offer multiplayer only, not the full campaign or special co-op modes. But you still get a great sampling of maps, weapons, and gameplay for that title‘s annual release.

The Best Ways to Enjoy COD for Free on Xbox

If you want to maximize your free Call of Duty experience on Xbox One, here are some tips I‘ve learned over the years:

  • Focus on Warzone – With frequent updates and live events, you‘ll get the most free content out of the dedicated battle royale experience.
  • Do Contracts in Plunder – Warzone‘s Plunder mode features contracts that give big XP rewards, helping you level up the free battle pass.
  • Play with Friends Who Own Premium Games – Party up to access paid maps and modes while playing together.
  • Follow News Sites for Free Item Codes – Redeem codes from sites like CharlieIntel for bonus cosmetics and double XP tokens.
  • Check the In-Game Store Weekly – Activision often gifts free blueprint weapons and operator skins.
  • Study Outside of Playtime – Watch strategy guides to improve skills in Warzone for free.
  • Link Accounts for Loyalty Rewards – Connect your Activision account to receive special legacy rewards.
  • Complete Seasonal Challenges – Timed challenges offer free blueprints, emblems, operators, and major XP.
  • Don‘t Waste COD Points – Earn and save premium currency through the battle pass to spend in Warzone.

As someone who loves maximizing freebies, these tips have helped me enjoy hours of Call of Duty multiplayer and battle royale without spending a dime.
