Get the galactic key to get past the door in the Veilstone galactic base and make your way to Cyrus's office and battle him. then he will tell you the warp pannel will take you to Uxie,Mesprit,and azelf. It's been awhile since i have been there but I'm pretey sure you battle the person in front of the button. When you beat him press the button and they go free.
In the veilstone galactic building. CAUTION!!!!!!!!!! You must have your best Pokemon because you must battle galactic boss Cyrus phew............I feel like a Pokemon nerd
Veilstone galactic HQ
go to the top of galactic HQ then go all the way to the right
In Pokemon Platinum, the player has to defeat several Galactic Grunts and Commander Saturn to get them to leave Lake Valor. This happens after Team Galactic uses a bomb to dry up the lake.
there are no team galactic grunts in that game. only team rocket, and they are not at lake of rage.
You have to free them by going to Veilstone and getting through the maze in the Team Galactic building. Then go there and you will find one of the legendary trio.
train
Go to veilstone in the galactic building I think
release the lake Pokemon in the Galatic HQ building
go to acuity lake (must have rock climb) then talk to Barry, then go to galactic Veilstone HQ building, and from there to Spear Pillar
Make sure you freed the lake Pokemon and battled Cyrus in the team galactic building in Veilstone city. The rest you find out. I can't give you the answer because this would be a cheat, and not a answer
after defeating commander Saturn at Lake Valour, you have to go to Lake Verity, fight four galactic grunts and then commander Mars.
