Your name is Doom Guy, an actor. You've been cast in a cable TV reenactment of 2007's "Knee-Deep In ZDoom". You were never much of a history buff, but it'll put food on the table and help cover Daisy's vet bills. Maybe it'll even revive your acting career. You adjust the prop helmet to breathe a little easier, try out a few cheesy poses with your character's handgun, and ready yourself for the first day of filming.
Welcome back to 2008, everyone! Knee-Deep in KDiZD is here, appearing courtesy of The History Channel. That’s right, it’s 2007’s Knee-Deep in ZDoom, now upgraded for vanilla Doom2.exe.
I didn't really expect a clearly infeasible joke project announced over a decade ago to actually become a playable WAD, but here we are
also I'm pretty sure several effects in this WAD are supposed to be impossible in the vanilla doom engine, and yet...
bonus content: I played this in prboom-plus without setting the required complevel, and got completely obliterated multiple times in the final boss fight, until I figured out that maybe spawning infinite fireballs is not how this is supposed to work and had some fun looking at the DEH file until I figured out I need to turn on the "limit to 21 spawned lost souls" compat option
