Billy Hatcher and the Giant Egg is a singleplayer and multiplayer third-person action-platform game developed by Sonic Team and published by Sega. The game uses a revised version of the Sonic Adventure 2 engine.[2]

Initially released for the GameCube in September 2003, Billy Hatcher and the Giant Egg received a PC port that released in European territories on March 31, 2006.[1] The port was later released digitally via GamersGate on March 26, 2009,[3] and was available until March 2, 2016.[4]

The PC version of Billy Hatcher and the Giant Egg suffers from poor optimization, improper sound mixing, severe screen tearing, and poor controller support.
