y'avais mon topic sur les secret du jeu pour ça mais bon, c'est devenu l'anarchie ici ...
Note: There are a total of 30 crystal skulls hidden throughout the game. All the skulls are found by the end of chapter 11. If you are following this in order to find them all, I've included the total amount you should have after finishing each chapter. There are no known in-rewards for finding them all. There are 3 achievements associated with finding them (20 gamer points for every 10 skulls found), and a gamer picture of a skull once you find them all.
Chapter 1: 2 skulls
1. Shortly after obtaining the fire ninpo, you will come outside to a ledge where you are supposed to jump off and land below to fight a bunch more guys. If you time it right, you can jump across to the roof on the other side and get a skull you should see from where you're standing. If you mess up, there's a ladder where you can climb up and try again.
2. Up next to the first flaming archers you encounter. Run up and jump off the tree halfway down the stairs as you walk towards the bridge they are firing from.
After finishing chapter 1 you should have a total of 2 skulls.
Chapter 2: 2 skulls
1. On the river bed shortly after learning the water-run technique. Near the end of the river before the bridge, its resting on the bottom. Hold A to dive down and pick it up. (Phatz2k)

3. After you pick up the spear gun and swim through approximately 2 areas, there will be a bunch of weird exploding jelly fish creatures (the second group you see) on your right in a small passage way.
