J M BerntsonJeeeeeez! Playing #MetroidPrime2 again, and I just played the MEANEST bit.
After getting the Seeker Launcher and returning to subterranean Torvus Bog, I had to take two big half-loops around the area to unlock a door in the central chamber.
Doing so blocked access to the save station. Onwards it is.
Found the Gravity Booster, forcing me into the super-mean Alpha Blogg battle.
Beat the stressful boss with 29/699 energy (health) and A LOT of unsaved progress.
