Map works good, all puzzles may be solved, only 1 mod conflict is present. In Beginning of level 4, task is exit from saferoom, obtain items and return in same saferoom. And something triggers survivors back in saferoom cuz of tank spawn, so that triggers antipharm plugin, who kills all players. If players enter in room and wait to pass countdown, they cant exit saferoom and progress.
That was before, that is present now, and is not big deal. In coop server works good.
May be some model conflicts, like no knife, map developer made his own knife for game.
Puzzles works good, MO disks may be found all and Bill may be rescued like 5th survivor.
