Looks great, sounds great, just the thing you want from FPS, not mentioning the Game play !!
you'll drive,swim,take buses,boats and swamp boats.
The story is straight forward but lacks some depth and feels shallow but it is not bad at all , plus the game makes up for it by presenting probably the best looking game this year after crysis and the great thing is, it doesn't eat up your system i have played it at a laptop to test it and it was smooth even at medium on a 8400m!!.
The weapons are looking realistic and are prone to jam if they are over used or picked up from the ground from dead soldiers which is an amazing add to the game, the guy you're playing with has malaria and as a result you have to go ask for the pills from another cells, and that means that you have to play nice to other people however the malaria sucks some of the fun of the game cuz you cant venture as you want into the wild fearing that you'll run out of pills.
but over all it still a very good game the sound tracks are amazing to give you the feeling of the african jungle you see lotas of animal out ther
controls are sharp and the saving system allows you to save any where
