from the .txt file included with the WAD:
“The Mars base, the center for all advanced scientific research of the UAC has stopped all communications with the PHOBOS base. You’ve done what an entire well trained millitary unit couldn’t do 2 times over AND gone through hell, and now the millitary thinks your tough enough for there biggest problem yet. Can you win back the base? Or have it’s occupants gottne too big a foothold This may become a level in a Shores of Hell replacer I may do, so yor comments are IMPORTANT!!!”
