Talk:Sequence Breaking
From M2K2: Metroid Prime 2 Wiki
In Venomous Pond, there is a Dark Temple Key that you 'need' Grapple Beam to get... Bzzt. Wrong!
Near the Save Station there are 3 Ingsphere Caches. You will need to practice L-Lock Jumping before doin' this simple trick succesfully.
After looking as far down as you can, hop onto the Biggest cache, and just jump to the key. Hooray! I haven't got far enough into the game to see where else you might not need grapple (I'm running through it a third time, on hard, and just found this trick) so anyone's help will be appreciated in eliminating Grapple Beam.
