During the 26th Anniversary Twitch Live Stream, it was announced that 1996’s Final DOOM would be available along with the 2010 expansion No Rest for the Living.
Final DOOM was a remixed version of DOOM 2 that reused much of its assets, but was notorious for its brutal difficulty.
There’s no word on when Final DOOM and its expansion will be available, only that it’ll be “soon”.
In the meantime, The DOOM Slayers Collection just came out for all your classic DOOM needs.
