SpyParty is a social deduction stealth video game developed by Chris Hecker.

SpyParty was first shown at the Experimental Gameplay Workshop at the 2009 Game Developers Conference.

The spy must attempt to blend in with a number of non-playing characters within a high-society cocktail party setting while completing a pre-determined number of espionage missions (such as planting a bug on a character designated “the ambassador”, or communicating a code phrase to a double agent known to both players) within a time limit.

[10] In early October 2013, Hecker and Cimino released new character and environment art to the open beta.

Chris Hecker uses the words "illustrative" and "timeless" to describe the new art style[12] and has stated a goal of being "the most diverse game ever".
