Tower Climb
Tower climb is a strategy in Jak and Daxter: The Precursor Legacy that allows Jak to reach the top of the cannon tower in Sentinel Beach without using the jump pad launchers that require blue eco. It allows Jak to collect the power cell at the top and access the cannon for blowing up the orb crates and the pelican.
