Hyperballoid HD

This sounds like a trophy that will take a long time to get but it's not too bad really. A reflection is a ball bouncing off your paddle.To get this one just play through the two campaigns normally, and it should just come naturally. Personally I got it halfway through the second campaign.

If you still don't have it after finishing both campaigns then you will just have to play through more levels until it pops, though you most likely will get it before this point. There is no way to check how far you are in-game as far as I know.
