Spec Ops: The Line Cheats
Installed it yesterday and so far you are right. The story and characters are wirth buying it so far. It strongly reminds me of various vietnam movies (of course Apocalypse Now where the story comes from) but also of others. Maybe the ingame music
So I bought it after all and can so far recommend it even if it is realy short
After hearing Yatzee over on Escapist mention that the story was good. I decided to get it and I have to say I am not disappointed at all.
