Ignore the early reviews, this game is much better since then and there were a lot of hype that got out of control. This is one of my favourite games out there thanks to the fun gameplay, story and characters. The Phantom Liberty is worth getting alongside this game as well.
To the point, shoot, empty the clip and grab a new weapon. slow-mo, slide, wall-run, jump and blast through walls and levels. This is a game for the gameplay, the story is minimal and stays out of the way for those that want to get straight to the action. The game is short but highly replayable and the levels are quick so you can blast around for a minute or two.
