Amnesia: The Dark Descent. This game is fantastic. This is the first video review of it. Amnesia will send chills down your spine but also let you pretend that you are all alone lost in a castle after having taken a couple doubled dosed hits. Watching as all the perspectives change shape, color and meaning until you find that last bit of tinder to light a candle and sanity comes rushing back. One of the best games I've played recently and definitely a throwback to Looking Glass Games - maybe even of a higher grade than classic Looking Glass games!http://www.frictionalgames.comhttp://www.amnesiagame.com
It should be worth mentioning that this stellar title (and it's technology) was somehow concocted by five people.
And it is only $20 when it would still be worth a $40-50 price tag.
