Metroid Prime 2 Differences - Early Dark Torvus Key Removed

In the original version of MP2, you can get the 3rd Dark Temple key for reaching Chykka (the one situated just above the entrance to Chykka's Lair), by Space Jumping from the tallest Ing Pod near the save station door. This removed the need to collect the Grapple beam JUST for that key.

This Ing Pod was removed from both the PAL and Japanese versions of MP2, forcing speed runners to perform a rolljump from the upper ledge, if they want to skip the Grapple Beam.
