This is not such a great game, the storyline of the game is really short, I mean, REALLY short. I have played heaps of first-player shooter games but none of the story mode is as short as this. Plus the gun variation is not alot. It also started to have glitches when I was half-way playing through the story mode. I checked websites to see if it's only my game that has the glitches but it turns out that most of the people have the glitches as well.
