I only played the BETA at the start, and here are the impressions I got: Negatives Freindly fire is on as standard, and this is very irritating as it is very easy to acidentally teamkill somebody when they run in front of you, as a lot of fighting takes place in tight corridors. You lose a LOT of points for this, 1 TK = a loss of the points for like 6+ kills. There is also a mechanic where if you "die" you have 5 seconds writhing in pain on the ground in which a medic can heal you. In practice this just seemed irritating also, as it slowed the game down and also no one seemed to play as a medic. Also on the 3 maps that were in the BETA there were a lot of camping spots, things like the tops of ladders and narrow corridors, where you were forced to move through to reah objectives, but could easily be held down by 1 person. Also grenades felt weak, making the camping issue worse. I didn't play the BETA at the end, so possibly some of this has been fixed. Positives You can choose guns in each class, so for example you can choose between different assault rifles on an assault class. Guns also feel well designed and balanced. The different objectives given in a round help to break things up and they work pretty well. Apart from camping spots there was good level design and art direction, I really felt like I was fighting on some hellish, wartorn planet. The Helghan are also well designed, not so much the humans, which feel pretty much like your generic future marine/commando force. There is good stat tracking, and the game also found games intelligently and many games ahd the full 32 players in them. I'd say the graphics were the best part of Killzone 2. Litterally everything is very well detailed, great lighting, great effects, etc. Apart from MGS4 i'd say Killzone is the first game to really push the PS3. The graphics are above and beyond what the Xbox 360 can achieve. (sorry MS fanboys)
