They praised the game's focus on fast gameplay and noted its similarities to the series' original 2D entries, a choice that some considered an improvement from the Sonic Adventure games. Sega released Sonic Heroes in Japan in December 2003 and worldwide in early 2004. The team revived elements not seen since the Genesis Sonic games, such as special stages and the Chaotix characters. The team wanted Sonic Heroes to appeal beyond Sonic series fans and so designed a game that did not depend on the continuation of its predecessors. Sonic Team USA's Yuji Naka and Takashi Iizuka led the game's 20-month development. The game was the first multi-platform Sonic game, produced for the GameCube, PlayStation 2, Xbox, and Windows platforms. Sonic Heroes abandons the action-adventure and exploration-based gameplay of its predecessors Sonic Adventure (1998) and Sonic Adventure 2 (2001) and instead returns to the linear style of Sega Genesis-era Sonic games. Within each level, the player switches between the team's three characters, who each have unique abilities, to overcome obstacles. The player races a team of series characters through levels to amass rings, defeat robots, and collect the seven Chaos Emeralds needed to defeat Doctor Eggman.

Sonic Heroes is a 2003 3D platform game developed by Sonic Team USA and published by Sega as part of the Sonic the Hedgehog series.
