Anyone still playing Doom out there? I came across a custom level I made way back in 1995 (give or take a year) and realized that the world shouldn’t be deprived of this great treasure.
I think it’s a decent, playable level, with good “texturization.” There are two difficulty levels: 1-2 is fairly easy, and 3-5 should be challenging.
Although the Doom source code is free software under the GNU GPL now, I don’t think that includes the main Doom “wad” with all the textures.
I haven’t tried running one of the GPL versions. To get the map and screenshots included here, I ran Doom95 under Wine. That worked ok except that I didn’t get any sound.
