Best Buy is selling Killzone 2 for the PS3 for only $29.99. Pricematch at Futureshop ($59.99) for an even better deal!
I just beat this game a few months ago and its awesome! No need to have played the first one to enjoy it. The graphics are amazing and is truly a next-gen game.
I’ve never tried the multi-player mode for this game yet, but I also heard it was intense! Soemthing to keep you busy until Modern Warfare 2!
