Everything ZombiLoin is saying is right. There have been youtube videos deconstructing The Line's deep meanings. I even read a loving book some game journo wrote about how deep it is. Someone actually wrote a book about how Spec Ops: The Line is an artistic masterpiece that parallels Heart of Darkness, a book that most people who play Spec Ops will have never read and most likely never plan to.
Then I played the game, realized it was nowhere near as interesting as people were telling me it was, realized that the setpiece cookie cutter roller coaster level design was pretty much exactly what I found wrong with most video games today, realized that no matter how much I wanted to like the game there was no excusing its stuffty gameplay, and concluded that Spec Ops is just a very mediocre game that wanted very very badly to offer a pointed and meaningful perspective on the philosophical ramifications behind endlessly shooting digital bad guys with virtual guns in fake middle eastern settings. Oh nooo i'm such a bad person how do i live with myseeeelf
Once I understood how stupid that sounded (I said it to myself out loud) I went and played a better game. I would recommend MGS, or Killer7. They're kind of like what Spec Ops tried to do except not complete failures of actual game design.
Spec Ops' story is pretty entertaining I guess. Once. Seriously, if you buy this game, I dare you to play it twice. You will fall asleep.
