This is the manual for Ultimate DooM, It originally came with the Doom Collectors Edition and I located it on Archive.org
This booklet does not belong to me and I don't take credit for it either, I shall also accept takedown if its not allowed.
To open this PDF file you need Adobe Document reader or Adobe AIR, Then click the manual and it will open allowing you to read it.
Ah, a classic! Thanks for sharing!
