I'm not sure if this is proper place to mention this, but it seems GameFly doesn't give you much options in this regard. I was unable to play this game whatsoever due to the disc being too damaged to work in my PS3. All my personal games and the other GameFly game that I had out worked fine, so I can only assume that the disc was scratched beyond the capabilities of my system to play it.
this game is a huge dissapointment. the graphics were horrable and the gameplay was horrable. you only get to 1 good level and then it goes back to the confusing and frusterating running aroud and shooting robots on foot. when your on foot, you die if you fly fast, so you can only do a slow hover. the story was bad, and i don't know what the prologue had to do with it. this game is horrable. don't even rent it!
