Wolfenstein II: The New Colossus and Wargroove will be added to the subscription service on May 2.
They’ll be followed by Tacoma, Black Desert, and Surviving Mars on May 9.
For the King will arrive on Xbox Game Pass on May 10, followed by The Surge and Lego Batman 3 on May 16.
While new titles are added to Xbox Game Pass each month, existing ones are also removed from the service on a regular basis.
Earlier this month, Microsoft announced Xbox Game Pass Ultimate. Launching later this year, it’ll combine Xbox Game Pass with Xbox Live Gold membership in one subscription package.
May’s free games for Xbox Live Gold subscribers are Marooners, The Golf Club 2, Earth Defense Force: Insect Armageddon and Comic Jumper.
