Third person horror adventure designed for Half-Life 2. No weapons, no fighting. Only means of survival is to run or sneak past the monsters.
Haven't quite beaten this yet but I've played through the mansion and I do love this mod. I can see the serious thought put into the game's design and the details such as the skins and level design/scare placement. Too rare do games scare you while not giving you assault rifles and this game succeeds in the penumbra/amnesia style of leaving you helpless. This is a good thing in my book because it puts the player on the edge of their seats as they grit their teeth doing things they normally wouldn't want to do but have to to survive.
Excellent mod
