(For: PlayStation 4, Windows, Linux, Mac OS)
Frictional Games' follow-up to its "Amnesia" series is as heady as it is horrifying. The derelict ocean floor research station PATHOS-II, a knot of auxiliary crimsons and steely echoes, is a sensory thrill. Cat-and-mouse games with the WAU, the corded flesh sacs that call it home, will slice right to your amygdala. Then your frontal lobe will light up at the existential what-ifs this dark descent forces you to weigh.
