Well, I played the demo versio, which I downloaded from the PS Store. I really had a hard time getting used to the gamestyle and everything. As I noticed, the gameplay is fast paced, so, you run, shoot, die, respawn and that keeps going on and on until either side wins. Also, it is really easy to die, or kill and opponent, like in one shot with a normal rifle, which I didn't really like. I really wanted to fly in a plane, but didn't know where to find one. I guess the flying part would be the best in that game.
Overall, I'd give a 7/10 rating for this game.
