There’s heartbreak, deception, and death-defying escapes. There are multiple sides racing to find the same treasure Nathan and Sam are up against a literal army of mercenaries.
Uncharted 4’s story is a pretty typical pulp adventure. Sam has been described as more reckless than Nate and a little jealous of his brother’s achievements. It is said his disappearance is what originally caused Nate to pursue a life of treasure hunting. Sam is five years older than his younger brother Nate, and previously thought to be dead.
