This game is an absolute blast to play. The campaign is very well written with great, informative cinematic part between missions. Also, most importantly, the campaign is LONG! Do not expect to beat this thing in 5-6 hours like a Call of Duty game. It will easily take 10+ hours. The first night I got it, my friend and I sat down and played the campaign in split screen co-op for about 6-7 hours and only got half way through, and the later missions take longer due to their difficulty.I'm not one of those reviewers that breaks down the game to scrutinize each part, I judge it on how much fun it is to play, and this game really is fun. The storyline is interesting, and the game play is great.I have yet to play online though I did play some split screen competitive with some friends, and my only gripes are that though you can only have 4 people play locally, their smallest map is 8 player, and also, you can't link two PS3's and play 4 person per PS3. When linking systems, you go down to 1 person per console. So basically you need 5 consoles for 5 people but only 1 console for 4. Very lame if you ask me. Also, the damage needs to be turned down to about 20% for any real fun game play, or else everything is more or less a one hit kill.As for the campaign, was that in co-op mode, the second player is just some random guy that is never mentioned in the storyline or cinematic parts, so he's like a ghost that appears and disappears.However, despite my gripes, I still gave it 5/5 for bot.
