Trophy Description - Completed a chapter only using Super Moves on enemies and without dying once.

Trophy Type - Silver

Use Chapter Select on Easy difficulty. Select chapter 8-3 Heavy Machinery since there are few barriers blocking your way to the end of the level. Run past all enemies collecting sunstone power as you go. By the time you need to fight an enemy, you should have 3 full rings of energy. Use the sunstone power of your choice on the 3 sets of enemies that will emerge from the walls. You will float up on a fan afterwards. Collect more sunstones behind a hidden wall to bring your total to 1 ring again and use it to finish the last boomerang enemy. This is a quick and relatively painless method to unlock the trophy. The hardest part is mentally forcing yourself not to use the Square button attack on enemies.

Trophy Description - Completed a stage without taking any damage on Hard difficulty or above.

Trophy Type - Gold

This trophy is less difficult than it sounds, especially after you've learned the ins and outs of the game by played on Hard multiple times. I chose to get the trophy on 1-2 Viktor's Challenge. Other players have suggested Chapter 4-2 because you can stealth kill your way through most of it and Chapter 8-3 Heavy Machinery since you can run by most of the enemies and traps. Just select the Chapter you feel most comfortable with and keep at it until your trophy unlocks. Use sunstone powers liberally on difficult enemies or to get through tough situations.
