[T]here are always those of us with fond memories of 1993 and the original Doom game, and just going around… well kicking ass. When Doom 3 was released, I decided to try my hand at mapping. I had no idea where to start so I figured I do something relatively easy by today’s standards – the angular corridors of The Ultimate Doom’s E1M1. So I did, and I enjoyed it. I finished the first version of it, and saw with the knowledge I had developed in the process of making it, that it was pretty bad. So I remade it. Scrapped that and remade it again. I developed this version and as I developed it, I changed things about the game and turned it into the basis for a mod. The mod is Classic Doom for Doom 3, and will feature the first episode of The Ultimate Doom. Not sure where we will go from there.
