short and sweet
Alright, so basically Killzone2 is an awesome FPS. Those thinking of buying should probably buy this game. This game was my first ps3 game and it made me go "whoa this is what games should look and sound like." Although this game was very action pact and make you jump headfirst into the war against the Helghast, I was a tad disappointed because the game took so long to finish. Let me emphasize on long because I saw Killzone2 videos maybe two years before it was finally finished and I remember thinking that game looks totally insane.
In conclusion, even though I was a bit disappointed, I rate it a 5 because the storyline is very good, the voice acting is good, and the multiplayer is pretty fun.
