Ya'ver drink Brazilian bold from fkn dunkn donuts!
Picked this up on sale, it has a very gloomy atmosphere, very little use of colour, but the art direction is pretty good. Plays like a First person stealth/combat game, not my favourite type of game to play, but there hasn't been anything yet to turn me away from it.
Performance wise it hums, with everything turned up (which is very little) and at 2560x1440 my 560ti cruises along with no performance drops or screen tearing. I did need to do some work with the controls to get the mouse aiming and sensitivity right.
Biggest complaint are there are plenty of textures that are very washed out and low res, coming from Bioshock it is a little jarring, but it won't get in the way of gameplay.
