Spec Ops: The Line, there isn't actually that much I can say about this game that hasn't already been said by many others, I will give it a shot though.
Spec Ops is a game where the mentality of always pressing forward, making the judgement calls as they come in the field is likely to get you.
It isn't a game where you know you are in the right, even if you make a questionable call every now and then, but you also aren't playing a deliberate villain, it is about the road to hell paved with good intentions and determination to do what needs to be done.
You won't walk away from this game thrilled, nor pleased with overcoming a significant challenge, the gameplay itself is only competent, not outstanding. It is however a story told very well, using a mix of cut scenes, in engine dialogue and animations, to reflects its shifting atmosphere, progressively getting darker and more vicious as you get closer to the end.
It is not a game I would describe as fun, it is however, a game worth playing.
