So a guy remastered a Doom1 screenshot, and it is the greatest thing I have ever seen.
The art piece got mentioned in DOOM twitter, and in the Bethesda Blog.

Check it out here:

Be sure to see it in full size. It is ENORMOUS and HD!!!!

He even made a video on how he made it:

Incredible.

If Doom1/2 ever got remastered, this would be the guy to get, to show what the entire game should look like.
