Microsoft announced this week that Xbox Game Pass subscribers will get access to "Retro Classics," an app they can download that contains more than 50 classic Activision titles from the 1980s and 90s.

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.

Microsoft's Xbox Game Pass is teaming up with Antstream Arcade to offer Game Pass subscribers a collection of retro games with titles from the original Atari, MS-DOS, and the PlayStation.
