when you get all the precursor orbs, you can go to the menu by pressing start and press on something that will let you use precursor orbs to by cheats like unlimited ammo,unlimited dark jak,unlimited light jak,hero mode which would let you start a new game with all your weopons that you got in the first game U also Get A New Costume Aswell.. But You Have2 Get All 600 Precursor Orbs!
There are 286 orbs in total.
there are only tips and tricks and where to find the precursor orbs locations unless you have a cheating devise that messes up the game code in your favor like action replay the only cheats are to get the precursor orbs and use them(if you get all precurser orbs your neck tie thing that he wears over his face in a sandstorm like a mask turns green) :)
i unlocked one once , you need to get lots of precursor orbs
EXTREEMLY DIFFICULT you have to get a lot of precursor orbs and get the invinsibility thing
you have to buy the replay thing with precursor orbs
600 it says in the secrets menu
You find Shadow Orbs at the bottom of the long, deep 'Corruption' shafts.
On the telegraph wires that stretch across the waters of the port. You can climb the two towers by hanging on the small pipes that are attached to the towers. For some of the orbs you must use the Launch Jump on your Jetboard
YOU CANT you have to find them the only way is to hack into the game which is what cheating devices do sorry how unfortunate i would be doing it right now if you didnt have to use a cheating device :(
nothing happens you idiot
Start a challenge and wait for the timer to reach zero, wait a second,and then punch at the orb at the last possible moment.You should get at least 3 orbs, it will say mission failed and you get to start over. Note:This takes practice.
Only way I know of is game shark or action replay,otherwise there is no way you have to find them,if you find all of them that gives you enough money to buy every single cheat also you cloth around Jaks neck will turn green instead of red.
