This is another trophy that is easily obtained via the first stage of the Echelon Territory. Pay no attention to the tutorial that runs through this stage, or the enemies that spawn. Just concentrate fire on the asteroids and you will finish the stage in under 60 seconds. (This may take you a couple of attempts).
