Thanks for all the Killzone 2 tips guys!! I'm thinking about trying for it next week and waiting to play God of War 2.
I'm a little bummed out after my first God of War 1 playthrough so I may take a break from that game. I just finished and I was 415 red orbs shy of maxing out all weapons and magic. So it looks like I'm going to have to play through 2 more times since I still need to complete the game in under 5 hours.
