Marathon: Assault
Read Me states two maps that have been lying around on the author's hard drive a long time. Author says there's a lot of bugs, smearing, and the story is incoherent. There are not two maps in fact, but one (and a minor transport), maybe to a semi-second level. Crashed the old Mac towards the end. We will have to stick with the author's assessment.
Levels in map "Assault .001.1":
Sludge Monster
And Not A Drop To Drink
