Secret Service is a first-person shooter video game developed by Cauldron HQ and published by Activision for Microsoft Windows, PlayStation 2 and Xbox 360.

It is set in Washington, D.C., on Inauguration Day, where the player assumes the role of an elite agent named Pierce, whose task is to eliminate enemies to prevent them from attacking the Capitol.

On the day of the Presidential inauguration, Secret Service Agent Pierce (Nolan North), a member of the personal detail for the current president, Simon (David Kaye), receives a phone call from an unknown caller (Michael Gough), whom he names "Semper"; Latin for "always" or "ever".

Pierce must fight, non-lethally (per Doyle's command), through Secret Service agents ordered to stop him due to going rogue.

He also comes in radio contact with the honest agents holed up inside the Oval Office with both Richards, who had since been sworn in after Simon's death, and Fritz.

IGN reviewer Charles Onyett awarded the Microsoft Windows and Xbox 360 version a 4.5 rating, praising some of the game's artificial intelligence for having a bit of challenge.

Writing for Official Xbox Magazine, reviewer Cameron Lewis called it a "decent low-rent shooter" with "uninspired level designs" and "dim enemies", giving it a 5.0/10.

[9] Paul Kautz of online magazine 4Players remarked on the game's short runtime of "[no] more than six hours" and lackluster level design.
