DOOM and DOOM II have received huge updates on Android that bring a wide variety of highly requested features to the mobile ports.
This includes 60 FPS, new aspect ratio options, quick save and load, a level select, and numerous quality of life fixes and performance improvements.
DOOM and DOOM II Now Feature Full Add-on Support on Mobile
Perhaps more exciting than all of that though, is new support for add-ons. This allows you to download new free maps for the classic shooter.
Right now, that includes SIGIL and Final DOOM along with more, and Bethesda plans to include even more add-ons going forward.
