Sizing Up the Trouble Pirates of Caribbean 2 Guide

The entirety of this mission is the fight with Pequeno. Throw everything you have at him while dodging cannon fire. After he starts climbing the walls, quickly grab the powder kegs and try to knock him off. Each hit deals him serious damage, three are required to gain another Map Piece.

If you don't manage to knock Pequeno off in time, brace for the impact wave caused by his fall.
