This is my first submission to the Doomworld forums and is a compilation of maps that consist of maps I have created and most importantly features maps from the early and unused DOOM 64 Level Designs forum post as featured in the post below   So get ready to mercilessly exterminate your way through hell, relive Doomguy's PTSD and complete the DOOM episodes once and for all      https://www.mediafire.com/file/crsm9ye4sykg49s/Doom_Extinction.zip/file
