Killzone 2 needs the Greatest Hits $29.99 treatment in North America. Now that the holidays are over, we should expect that soon.

It was one of Amazon lightning deals for 29.99 during the black Friday sales week and sold out in seconds!  That seems to be the right sales point for the game!

True...
