Metroid Prime 3: Corruption Tips

Power-Ups not on the map
If you, like so many others, relied on the map but found yourself short a few % marks, you've probably overlooked the upgrades that aren't on the map:

-The GFS Valhalla upgrades are not listed

-The two upgrades (not counting the screw attack) on Bryyo Ice are not listed (well, they are, but you can only see the map of that area 'in' Bryyo Ice, so scanning the planet won't let you see them unless you travel through the warp point.)

Happy hunting!
