In this new NEFX scenario shell for Marathon Aleph One, you're a pedestrian trying to get past a crowd of other pedestrians to get to the exit, in part by yelling and shoving. But no one can die, so be patient, persevering, and careful about where, when, and how you shove and yell.
Today I added one new map for Marathon: BOBJam, "How Originary Understandings Get Re-Reached". This can be downloaded individually or with other maps or the scenario itself at the provided link.
