* Psychological horror

Has several notable differences to other horror games.
* Fragile protagonist — can't survive much beating, also often has much more adverse effects from damage than just numeric loss to health (e.g. limping).
* Limited munitions — weapons tend to be ineffective and ammunition is hard to come by. You can't even carry very many of them or much ammo even if you do find them.

Players accustomed to other types of games may not realize that they're meant to run away from the enemies more often than to shoot every single one of them to death.
