A campaign leading the survivor through different dense inner city areas, starting in some industrial backalley, and ending with the ominous "Infinity Recall" (In map 5).
A very creepy campaign spanning from a disturbing chasm, a series of dark corridors, some sort of cave thing, a long span of breakable platforms, and a big demon thing for the finale.
Your hapless band of misfits picked the mouth of this creek to land their sinking dingy. You hoped for safety. Welcome to disappointment village. Population YOU.
