I wouldn't say I've been itching to return to Amnesia: The Bunker, Frictional's perfectly ghastly blend of horror game and immersive sim, but I've certainly been itching to write about it. The terrible beauty of that generator-based exploration and scavenging loop. That moment when you walk just a little too quickly down a corridor, and hear the awful rummaging in the walls. The agonising discovery that not only is it possible to roam with the lights out, but pretty much required, beyond a certain point. The dense burden of grasping more or less where to go, without knowing how to survive the journey - and above all else, those goddamn rats, always encountered where least convenient. Shoo! Shoo!
It's by far the most oppressive and demanding horror game I've played in recent memory, and it'll get considerably worse with the release of the Halloween update.
