Recently Microsoft has been testing a whole bunch of classic old-school id Software and Bethesda games on the Windows 10/11 platform - and today the first batch of those games have arrived on PC Game Pass. A list that includes The Elder Scrolls Adventures: Redguard, Wolfenstein 3D, and Quake 4.

This is very cool to see because a lot of these games date back to the MS-DOS and floppy disk era of PC gaming.

Here's the list. And as a nice little bonus for Xbox Game Pass Ultimate subscribers (which bundles PC and Console) all Champions will be unlocked in Quake Champions.
