Which Uncharted game was released exclusively on PlayStation Vita?

Uncharted: Golden Abyss was released exclusively on PlayStation Vita.

Developed by Bend Studio and published by Sony Computer Entertainment, Golden Abyss was designed as a launch title for Sony's handheld system. It is a spin-off and prequel to Uncharted: Drake's Fortune, following Nathan Drake during an earlier search for the lost city of Quivira. The story also introduces fellow treasure hunter Marisa Chase.

The game adapts the series' climbing, shooting, exploration, and puzzle-solving to Vita hardware. Its design uses the system's touchscreen, rear touch panel, motion sensors, and cameras alongside conventional controls. Players can swipe during melee encounters, tilt the system while aiming or balancing, and use touch-based interactions to examine clues and solve puzzles.

Golden Abyss is often confused with Uncharted: Fight for Fortune, another Vita-related title, or with The Nathan Drake Collection. However, Golden Abyss was not included in that PlayStation 4 compilation because its standalone story was considered separate from the trilogy being prepared for Uncharted 4. It remains the series' major platform-exclusive Vita adventure.
