for PlayStation 4, Nintendo Switch, Xbox One, Android and iOS on July 26, 2019, during QuakeCon, in honor of the franchise's 25th anniversary. Bethesda received criticism for allegations that it included additional digital rights management in this version, as the initial releases required that users sign into a Bethesda.net account in order to play. Bethesda later stated that this was not intended to be mandatory, but an optional link to receive rewards on the service's "Slayers' Club" program for Doom, and that the mandatory login would be removed in a patch. This initial release for Doom 1 and 2 in the 25th anniversary release was also plagued with uneven pixels, incorrect aspect ratios (no option for 4:3), incorrect lighting position, and the music not matching the original DOS release version. On January 9, 2020, Bethesda released an announcement that Doom 1 and 2 will have a patch and update fixing the problems that plagued Doom 1 and 2's initial release. Updates including quick saves, support for 60 frames per seconds, 4:3 aspect ratio support, and support for add-ons (such as Final Doom and "No rest for the Living").
