Completing The Scrapyard stage in under 15 minutes is another fairly easy goal as there is no boss at the end of it to deal with so that will help cut down on time. The main headache with this level is just knowing where to go as the camera tends to go funky and doesn't lead you to your next spot to advance forward. You will want to make sure you avoid anything that you don't need to be doing in order to advance yourself in the level. Don't bother breaking boxes, exploring, upgrading or fighting with enemies that won't release you from the energy barricades.

I would use someone like Grey Matter for the majority of the stage as he is very quick and can get you through it fast (if you want to use someone else to battle during the stage in the required fighting parts that's fine). Once you finish The Scrapyard in under 15 minutes, the trophy will pop.
