you have to play the missons and sometimes do some extra things during the missions and protect club penguin
The Xbox Elite is only worth the money if you need the accessories and want have a complete system out of the box.
you must complete all 300 standard missions not including the extra missions that are unlocked from beating the game
there are unlimited missions but u need to complete only 12 to get its percentage in game completion and receive a few extra benefits.
You just do the mission again, and you beat the high score or extra assignment, then you will have finished it.
first you need a internet router on and go to ranger net in the Pokemon ranger menu and download all extra missions and complete them then more missions will appear complete them all and then mission manaphy egg will appear complete it and then if you hav two ds and Pokemon pearl or diamond you can transfer the manaphy egg to diamond note: extra missions can only be played after completing the game note:for more info go to youtube
You need to get complete all story missions and get all extra requirements in the challanges.
In Peacewalker, to get armor you need to complete the Main Ops missions. In a few of them, you have to look for little boxes that contain armor and will be unlocked at the end of the mission. Also if you complete the Extra Ops missions and get a S++ rank, I believe you obtain armor from that also.
Well you have to complete the "ICE BERG THREE" missions and then you will get that name. I hope you that this is helpful.
