Before I go blabbering away like a little schoolgirl I would like to give a shout out to playstationdirect.net, our new partners.
First off here's the gameplay video for Motorstorm 2.
Next, a new gameplay video of Killzone 2.
Finally, Resistance 2. Notice the 3X, 4X, 5x markers above their heads. It's supposed to give you bonus points for killing people on a streak. This could be a good or bad feature depending on how its implemented.
