Metroid Prime/Boost Ball

Phendrana Shorelines
Scan: Crystallite, Flickerbat

Coming out, you need to go through the only door in the wall to your right. But if you attempt to address it directly (there is a series of ledges) you find it is artificially locked with the kind of blast shield not to be addressed with simple missiles. The console to unlock it is in the protruding tunnel just beneath. There is a Grate in the way, but it 'can' be blasted with a missile. Go over the snow drift as a morph ball, and scan the console. Now through the door above.

Proceed to the Ice Ruins Access.

Ice Ruins Access
Scan: Scatter Bombu

Blast through an ice wall, and scan another kind of Bombu, then proceed to the Ice Ruins.

Ice Ruins
Scan: Baby Sheegoth

This room is moderately simple. You need to proceed right by going left. First take out the Baby Sheegoths. Then follow the curve of the room until you see a stack of crates on the only ledge you can jump on to. This is your break. Follow the ledges and rooftops around to the left until you've put the next exit directly to your right.

Proceed back to Phendrana Shorelines via the Plaza Walkway.

Shorelines Redux
Same room, higher up. Now go higher. There's a door to your Left. Proceed to the Ice Ruins West via the Ruins Entryway.

Ruins Entryway
This time I'm afraid you'll have to proceed left by going right. Go straight ahead (past the Sheegoths - there's no avoiding them) toward the left side of the room. A hard right leads to your door.

Proceed to Phendrana Canyon via the Canyon Entryway.

Phendrana Canyon
This room looks ugly, but it's really simple. The Boost Ball is high up on a ledge at the far end of the room. There are hovering platforms all the way across, but they're at the wrong levels. Half-way up a slope on the right is a terminal. Scan it, and the platforms will align. Follow them and you've got the Boost Ball.

Wasn't that a long enough journey?
