I call this the Genocide Center because there's tons of victims just hangin' around (ba dum tiss). Also, a few impaled zombiemen are in here, but don't worry, they don't bite. Note: This is not a reference to WWII genocide. Just genocide in general.
Well, the DOOM wiki for giving a lot of helpful information, DOOMworld.com for helping me figure out what editors to use, and DOOM Builder 2 for making such an awesome level builder with an incredibly user-friendly interface. Oh yeah, and iD software, yall are the best!!
New level from scratch
DOOM Builder 2, Wintex 4.3
Well, a couple of the textures aren't well aligned, but that's about it.
