A port of Secret Agent Clank, a platform video game developed by High Impact Games and published by Sony Computer Entertainment, released for the PlayStation Portable (PSP) in 2008.

In the game, Clank dons his "Secret Agent Clank" persona, which was previously seen in brief TV show segments within the main series. The story revolves around Clank working to clear Ratchet's name after Ratchet is framed for a crime he did not commit. The gameplay diverges from the traditional Ratchet & Clank format, focusing more on stealth and gadget-based play, though it retains the series' trademark humour and style.

The port is enhanced with up-rendering, rewind, quick save, and custom video filters.
