Killzone 2 has been on our radar for quite some time now. It's the sequel to the first one on the PS2, which I personally didn't find too appealing, but after the avalanche of screenshots and videos that have populated the 'Nets over the past two days, it's easily becoming one of the must-have games of 2009. Above you'll find a quick demo of the game's physics, including grenade throws and explosions, and the superb gun play that'll have you rattling bullets into opponents for a long time coming. Killzone 2 invades the PS3 just after Valentine's Day (perfect way to say, "I love you."), February 17, 2009.
