This was the second time. The first time he got as close as he was here, then left, this time, he did the same, so I remained where I was, but he came back. I decided I should move, so I went up the long, one-way corridor from whence he came. He was still about, so I made some pretty careful turns before spotting a cinematic brute, which made me collapse form insanity. I crawled to a nearby prison-door and hid, eventually the grunt left. Amnesia's a pretty epic game.
Can't wait for the sequel, I won't be late to the party this time!
