Received free from Humble Bundle.
Pro's: This game is extraordinary. The graphics, the story and the intense combat situations which are realistic, tense & heart wrenching. This game is like none i've played before, plucking at my heartstrings. You get an emotional attachment to the characters, and finding the dark truth of others. The ending was by far the best way this game could have ended, short and sweet to meet my satisfaction although without spoiling it, just wow. This game took me a little over 5 hours to complete on Medium Difficulty (Average). I would strongly recommend this game to anyone who loves 3rd person shooters, realism games &/or Combat scenario games. One thing i was surprised with was the fantastic voice acting which i wasn't expecting from this game in the slightest. 10/10 however buy on sale because of the small gameplay time.

Edit: After going through & completing this game on every difficulty & getting all achievements I have some notes, firstly I'd recommend the 2nd hardest difficulty setting (you unlock FUBAR once completing the game with this difficulty).
The reasoning for this is that it makes the game feel a lot more real & giving it a real sense of challenge plus you really have to take cover, use the team management system etc.
Another thing is that there are 4 different endings, which at the time of writing my review I hadn't even discovered. The ending to this game will have you in shock for sure, playing through for the 2nd time (and so on) makes you understand what a lot of the earlier conversations etc meant which is really interesting.
