It seems crazy that people are still making hugely popular DOOM mods in today's age, but alas it's still a thing. An no, I'm not talking about mods for the 2016 DOOM game from id Software, I'm talking about mods for DOOM 2 from way back in 1994. In this case, modder Doug Keener has recreated Jerry Seinfeld's apartment from the popular TV show in DOOM 2. Check it out.
The YouTube description for the video has a disclaimer up just in case any outlets or individuals try to spin the mod as some sort of hate content. Doug Keener writes...
Keener's mod allows players to walk through the a small segment of the apartment's hallway and then enter into Jerry's apartment, which is fully fleshed out with tons of props, custom textures and furniture placement.
For some of you old-school enthusiasts who may have noticed that it appears as if some of the content is scaled with more precision than what most of the standard DOOM level editors would allow, your suspicions are correct. Keener used the GZDoomBuilder along with GIMP 2.0 to craft certain level features, including the 3D tables, desk, and chairs you see in the video above.
In the standard DOOM 2 editors you couldn't make 3D objects because at the time the engine did not support 3D at all. Mind blowing, right? In order to create the appearance of 3D it was possible to utilize certain texture glitching tricks to make textures on the lower or upper half of objects appear to be be transparent. Of course, if you tried walking through or past those objects you would hit the wall.
In this case, you can see that there are actually legs on the table and the chairs actually have 3D spatial height and depth, and this is all thanks to the power of the modded version of GZDoom, an alternate executable of the standard DOOM.
The most impressive thing about this mod is that it's so dense with detail. From the carpet textures and the multi-colored table to the sofa, the posters and picture frames on the walls, and even the details in the blinds over in the corner by the computer... it's all made with impeccable detail. It's topped off with a midi rendition of the music played from the Seinfeld television show, and the monster sprites were replaced with the cast of characters, each with intro and death phrases.
It took Keener 100 hours to put this modded wad of Seinfeld together for DOOM 2, and you can test it out for yourself by grabbing a copy of the mod from over on the Doomworld forums. The mod will only work with a DOOM 2 iWad, so you'll need a legit copy to play.
