As much as I hated FEAR Extraction Point, the way they made a hospital of all places scary was brilliant. I guess we all have a natural, in-born, primal...mistrust, I guess, of hospitals, because I know I wasn't the first one to say that. I remember that part with the 3 bloody clawprints on the door that mean you're about to fight some invisible ghosts, I froze and still have yet to play that part.
For background, these ghosts kill your two squad mates: the first one is ripped to shreds in front of you, after walking through a warehouse filled with corpses, with your squadmate saying that all of them (some were the enemy soldiers, some civilians)had tried to lock themselves in TOGETHER, which is remarkable knowing what you know at that point about the Replica soldiers: how hard they are to scare, how brutal they tend to be toward civilians, etc. I can't remember if the ghosts got through or if it was suicide out of sheer terror. Anyway, your squadmate and you go into the main room, with blood on the floor. When you get to the middle the lights flicker off. When it flickers on, there are 3 no-longer-invisible ghosts floating in front of you. The lights flicker again, then there's 5, then 7, etc till there's about 13. Your squadmate gets lifted off the ground, gets the shit kicked out of him by being thrown against walls, he gets pulled into a door, is holding on to the frame for dear life (literally), says "Find Jin" (Other squad member who got seperated), you see several ghosts waiting in room, he;s pulled in and door closes, he screams, he is thrown back into main room through the wall, thrown around again, thrown outside, and is hanging from a window, clearly dead. When you approach it, it gets pulled into the building in a spray of blood.
The second one is guiding you up the building that connects to the hospital over a radio, when she starts to get weird. When you're a floor below her, you here her scream, you run up the stairs, and find the ghosts standing over her corpse with her camera (she was in charge of forensics) lying on the ground, constantly taking pictures of her body.
You only actually fight them twice, one of them being the time I mentioned where I couldn't continue, the other time being earlier. You find the door with the mark I mentioned, open it, the floor is covered in blood, and invisible enemies are ready for you. The only reason I beat them with a minimal of fear was because this is, if I remember right, before either of your squad mates dies, so you don't really know what they can do.
