Secret Agent Clank is a platform video game developed by High Impact Games and published by Sony Computer Entertainment. It was released for the PlayStation Portable (PSP) in 2008 and later for the PlayStation 2. The game is a spin-off from the popular Ratchet & Clank series and features Clank as the main character in a secret agent role. 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.

Clank's on a mission. His best buddy, Ratchet, has been framed by a ruthless enemy and jailed for a crime he did not commit. Not only that, but Ratchet's maximum security prison is full of the universe's most dangerous criminals most of whom are lining up to personally "welcome" Ratchet into his new cell. Luckily for Ratchet, he's got Clank on the outside, and luckily for Clank, he's the kind of brainy little robot who is cool under pressure and knows a thing or two about tracking down a mysterious enemy. That’s why, as Secret Agent Clank, he's hot on the trail of clues to unravel the mystery, secure Ratchet’s release from jail, and save the galaxy!
