The demons came and the marines died. Except one. Your are the last defence against these hell-spawned hordes. Prepare for the most intense mutant-laden, blood-splattered action ever! The texture-mapped virtual world is so real, you don't just play DOOM - you live it.
A patch to make the steam version of The Ultimate Doom to work on modern machines
How to install: Extract "The Utimate Doom.rar" onto your desktop, you should now see 4 different files, Now go to your steam library and right click the the Ultimate Doom, then go to Properties>Local files>Browse local files and open up the "base" folder. Now highlight the 4 files and drag them to that "base" folder you opened up. When your pc asks you if you want to replace the files, click on yes.
Vanilla The Ultimate Doom should now work on your system :)
