Surprise! If you are a Game Pass subscriber, you now have access to dozens and dozens of retro video games. And Xbox and Activision plan to add even more classic games in the future.

Game Pass members can now play over 50 old-school games for free. Microsoft's Retro Classics is a library of old-school Activision and Blizzard games from the '80s and '90s, like Pitfall! and MechWarrior 2.
