This WAD is a replacement for episode 1 with 9 levels meant to be played with the original Doom1 WAD. It uses only resources from that game and is meant to be a homage to the original trilogy. Currently, this runs on Zdoom/GZDoom. The nine levels take you from the Mars UAC base to the Phobos base, and then into hell. It's meant to be harder than the original trilogy, but not brutally so.
