I finished Killzone 2 the other day, the final showdown was solid (I mentioned it earlier but it involves a lot of enemies keeping you on your toes), and then you face off against the main guy. It was tough but damn satisfying to finally get through it all, and actually have a finish that challenged me.
The story isn't the main focus of the game, but the cutscenes and exposition thas there is good, it'd just be nice for shooters to put more effort into the story and making players interested in why the characters are doing what they are doing, KZ2 is guilty of not revealing as much as I'd like (most shooters are like this at the moment [Gears 2, Halo 3, Resistance 2]) and it's a bit dissapointing.
The shooting never got old, the set pieces were awesome and varied, the only thing lacking was vehicle sections to break it up a bit, there were some but not enough. There was one short section where you are in a tank and that was cool, and another one where you are in an AA gun on a big space cruiser and it's like something straight out of Star Wars which was awesome too. The best vehicle section was where you get in this fantastic mech/exo suit, the first person view you can see is great as you can see how your (characters) hands control the suit, and as the suit takes damage the glass casing you in starts to crack, it looks really good, and jumping into the air and landing on Halghast is so much fun.
They need to make a multiplayer mode where everyone is running about in the suits.
Exo suit gameplay here.
The online is deep and satisfying also, the only thing I wish it has is the Replays that Halo 3 has, that was easily the best thing about that game, the stat tracking on killzone.com is good as well, it tracks a lot of stuff from your Multiplayer matches and single player campaign; and the intel you find in game unlcoks some stuff you can print out or use outside of the game, like wallpapers, propaganda posters to print and theres some great papercraft stuff you can get too, like this:
KZ2 has some of the best uses of the SIXAXIS as well, with the sniper rifle you have to hold your hands still to keep the scope inthe game steady. Theres parts where you have to turn the controller to imitate turning valves and setting explosives, it doesn't feel intrusive, it doesn't occur often (or it would probably get annoying) and it's more intereting than "Press Square" or "Tap circle".
There are niggles and downsides to it. Some of the voice acting and dialogue in general is poor, none of the guns have secondary fire which was one of the best things aboutt he original and it's a bit of a shame. You can only carry your pistol and one other weapon, which limits your choices a bit, it would be fine if you could only carry any two weapons, but being limited to only your pistol and one other is silly, as it means I'll rarely use a Sniper rifle or rocket launcher as they are only useful in specific areas.
The shooting side of it is just fantastic though, loud brutal and fun. The cover system is all in first person and works brilliantly, I like that when your ducked behind cover reloading enemies will take the opportunity to move from where they were before, which can catch you off guard. Speaking of which the enemy AI is phenomenol, they know when have a bea don them and will move positions whilst behind cover so you can't keep your sights on where their head popped out before and kill them, they run from grenades (unless you cook them), they flank, flush you out of cover, move intelligently between cover, blind fire after popping there head out to see where you are. It's fun and challenging to take enemies on all the time.
Theres a unique sort of animation system in place for deaths as well, it takes into account the weapon you've used, where you've shot them and what the enemy was doing when you shot them and it makes the deaths realistic and varied.
Fantastic game, will maybe talk about the multiplayer more later.I forgot to mention the visuals, but needless to say they are amazing,particularly the lighting. The game has some of the best instances of wind/dust clouds and general things flapping from the wind, which sounds silly but it was a cool detail to notice. The textures are nearly all excellent I only spotted a couple of poor textures but thats the same with any game.I think it's really set the bar for FPS games in the future.
