This was a great game! The actual game length is probably an hour, but it takes longer because the game gets hard during the gray zones boss. (This isn't what brought down the rating.)
It has a nice soundtrack, not too loud but not too quiet. It has a mix of techno-like music and general shooter game music, and the remixes are great too.
To me, this is more of a little time killer that you would have to play on a unblocked games site while you wait for class to end, you know? Like, I wouldn't play this over other games, it's just when you get bored of those other games.
I can't tell if it's a bug, but whenever you load back into the menu, or into a zone, the volume will be set to max which is kind of annoying if you have to lower it down constantly (like if you're wearing headphones). This is what brings the rating down to a 4.5.
