Regardless of which route you chose, you'll wind up on the far right corner ledge. This ledge is stable and a good place to quick-save.
Turn right and walk out to the pointed edge of the corner ledge.
Take a standing jump to grab the next tall block.
Pull up, run forward before the block collapses, and vault onto the next higher block.
Without stepping forward, take a standing jump to grab the next ledge.
Pull up and quick-save again. (If you're that kind of person. I certainly am.)
Now there's just one crumbling walkway between you and the prize. Turn right, run forward along the right edge of the walkway (the left side is unstable)...
...and jump into the alcove as the block connecting the walkway to the alcove drops away.
When you make it, the camera shifts to show most of the remaining ledges falling into the abyss.
Enter the alcove and pick up 2 boxes of V-Packer shells (2-3) and the EARTH CRYSTAL (4).
Shards of rock swirl up from below, rebuilding the floor. If you crossed on the left side of the room, the "Live Dangerously" achievement/trophy unlocks here.
DARK MODE: I plan to add optional dark mode for these pages, but my current priority is updating the walkthroughs. Meanwhile, may I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's web store.)
