Project Eden is a 2001 action-adventure video game developed by Core Design and published by Eidos Interactive. It was released for Microsoft Windows and PlayStation 2. The planned Dreamcast version was cancelled. The plot involves a squad of four law enforcement agents investigating the disappearances of people by working their way downwards through layers of a towering mega-city. Project Eden's gameplay emphasises puzzle-solving, requiring the player or players to control each of the four characters and use their individual abilities to make progress. A single player can control any one of the characters, and jump between them at will or up to four players can play simultaneously as different members of the team.

Core Design Limited was a British video game developer based in Derby. Founded in May 1988 by former Gremlin Graphics employees, it originally bore the name Megabrite until rebranding as Core Design in October the same year. The company was acquired by umbrella company CentreGold in December 1994, which in turn was acquired by Eidos Interactive in April 1996. In May 2006, the Core Design personnel and assets were acquired by Rebellion Developments, and the company became Rebellion Derby, which was then shut down in March 2010.
