Skipping the Boost Ball: Vent Shaft Dash

Discovered by

This alternate method of getting through Vent Shaft without the Boost Ball is considered easier by many.
First, jump up toward the target ledge in Vent Shaft to reload the room behind you.
Then lock on to the Wave Trooper as shown, being careful not to let the lock pass over the closing door.
Dash Jump from the tiny ledge and pull backwards. It may help to press L just as you feel you are passing in front of the ledge.
