Playing Doom Inside Doom
There is nothing that epitomizes the quest for the ultimate Doom port than managing to get the 1993 game running inside Doom. The hack from YouTuber kgsws exploits a flaw inside the DOS version of Doom II to play the Chocolate Doom as a moving texture. The modder made a custom movie theater level inside the game to try it out, and while it won’t run with sound, it still controls surprisingly well for a 30-year-old game running inside a 30-year-old game.
