Madagascar. The Uncharted 4 campaign at full expansion — the environments, the vehicle traversal, the partner dynamic of the Drake brothers established and tested. Avery's treasure is the game's MacGuffin and its thematic vehicle simultaneously: a pirate colony built on shared profit and shared idealism, destroyed by greed, the treasure a monument to what happens when the trust breaks. Nate and Sam hunting for it is the game asking whether two brothers who have their own trust history can do better than Avery's crew did.
