What a Game
Is a sort of mix between Doom3 and F.E.A.R. Graphics are eccellent. Great shadows great reflexes. New weapons without forget the old ones!
Audio very good and intense.
AI very good on medium and high difficulty.
Gameplay: normal it is easy to play and also to learn playing!
I think is a great success of valve the only pity is that internet is required! A lot to say also on Counter Strike Source: one of the best games i ever played.
If you want a better opinion try it yourself!!!!! is the better way to judge a game!
