I actually completed this one yesterday, did it on my fourth or so try. Just as Oz says concentrate on the asteroids that come in the centre of the screen, but of course try and get as many of the others aswell. If you don't get it just quit and load to try again.
Developers was nice to us leaving a savestation right before this trophy
ain't that the truth!!
I am so close to getting this platinum, which would be my first!!
This game is also proof that a game doesn't need online to be a good game or be successful. That had already been proved with Uncharted and Ratchet of course!!
