I heard a lot of good things about this game. And it is one of the games that actually lives up to all the hype. For me it actually even exceeds it a bit.

The graphics look pretty good for a game, that came out in 2012 (the Dubai setting helps that a decent bit). The sound is done well, but is not overly memorable.

The gameplay is simple, but it works well. There are also different types of setpieces and game mechanics (such as sandstorms), that vary up the gameplay from in interesting ways. Although, the control scheme could have been done better, because you use one button for multiple actions (even on PC). The gameplay also compliments the story a fair bit.

The story is this game's selling point and the game succeeds in every aspect of it. The characters are well written, their performances are very good and the ending may blow your mind.

One thing that you need to also keep in mind is, that this game is fairly short. I finished the main story in about four and a half hours, and there isn't much else content, as the multiplayer and the coop are dead.

But for under 5 bucks, I would easily recommend this game to anyone, that's even remotely interested in military shooters, as this is something fresh and different in this genre.
That's why I'm giving this game an 8/10.
