This game is really great. When it comes down to it, it really delivers. The gameplay is what you'd expect from a first person shooter. The movement though i find is sort of like Halos. For sure not as fast as call of duty witch is why it took some time for me to get used to it. But once you've played for a couple of hours you get really into it. You just really want to unlock the next character specialty. The sound is perfect and theirs a voice that will talk in the back round witch makes the game all that more immersive. Sound is perfect. Weapons are great even though there aren't many weapons, each one is very different. Like you'll have two different assault rifles but both of them control very differently. The sniper takes a bit of getting used to probably more than the other guns i'd have to say because it moves quite fast once you have it in scope. Now for the graphics. My God. If you have a crappy run down little tv i will pray for you. Cause this game needs hdmi. If you can get this game on even just 720p, you'll be amazed. It looks like a movie on 1080p. Great game, get it, play it, enjoy it.
