These pull of horror much better IMO.
Amnesia is in a different league as it presents horror in a whole different fashion. They have literally redefined the meaning of survival in their games.
They basically take the ability to fight , out of the equation leading into evasive strategy only. This aspect amplifies the horror quotient in their games ten fold.
Amnesia: Dark Decent is the most terrifying game that I've ever played. The creepy environment design and the inability to fight back against those hideous monsters,
is what makes the game one hell of a horror title. This is the only game i couldn't play in the night alone with headphones on. Besides, the game also brings complexity into the picture
in the form of puzzles, traps and non-linear progressive game play. I also got lost in the game world a lot of times and had to take help of a strategy guide.
Amnesia : A Machine For Pigs should be a must play for all horror fans, of course including "The Evil Within".
