In the final level of Blood Omen 2: Legacy of Kain theres this huge, unkillable demon thing that pretty much chases you through the level and appears every now and then. i dont know why now but that thing scared me. also, the Eternal Prison was just plain scary. the inro video for the level was bad enough but going through it was really creepy. but when i played the game a second time, the demon thing just got in the way but the eternal prison still creeped me out.
