Jak 2 Renegade Hints

Press this for a 5 hit combo move:
square,x,square,o,o [note:you have to press the second o when youland on the grouund after the first o]

Go to the mission were you find the precursor artifacts with those huge metal head rinoes and destroy all the metal heads on that level, collect all the skull gems and commit sucide then recolect to end up with a large amount of skull gems. if u mant more repeat process to get the amount you want but this cheat will only work if u finished the game.

If you do a level and you think it's not worth saving and you collect some orbs. the game will probably save the orbs you have collected so the next time you play you can go and recollect the orbs you have alreadt found

(this has only been tested once)

If you find and orb or two and your stuck on a mission dont save any progress because if you find and orb you can go and recolect that orb

the metal head nest is really good spot to start this cheat (look behind the gun)
