Sonic Adventure 2[a] is a 2001 platform game developed by Sonic Team USA and published by Sega for the Dreamcast. It features two good-vs-evil stories: Sonic the Hedgehog, Miles "Tails" Prower, and Knuckles the Echidna attempt to save the world, while Shadow the Hedgehog, Doctor Eggman, and Rouge the Bat attempt to conquer it. The stories are divided into three gameplay styles: fast-paced platforming for Sonic and Shadow, third-person shooting for Tails and Eggman, and action-adventure exploration for Knuckles and Rouge. Like previous Sonic the Hedgehog games, the player completes levels while collecting rings and defeating enemies. Outside the main gameplay, they can interact with Chao, a virtual pet, and compete in multiplayer battles.
After the release of Sonic Adventure (1998), Sonic Team was downsized and a portion of the staff moved to San Francisco to establish Sonic Team USA. They worked on Adventure 2 for a year and a half, with Takashi Iizuka directing and Yuji Naka producing. Developed during a tumultuous period in Sega's history, Adventure 2 had a significantly smaller development team than the first game. Sonic Team USA streamlined the design to emphasize faster, more action-oriented gameplay giving each character roughly equal gameplay time. The levels were influenced by American locations such as San Francisco and Yosemite National Park. The soundtrack—composed by Jun Senoue, Fumie Kumatani, Tomoya Ohtani, and Kenichi Tokoi—spans genres including pop-punk, glam metal, hip-hop, jazz and orchestral arrangements, and features several metal singers.
Sonic Adventure 2 was released in June 2001, coinciding with the franchise's tenth anniversary. It was the final Sonic game for a Sega console, released in the months after Sega discontinued the Dreamcast and transitioned to third-party development. Later in 2001, it was ported to the GameCube as Sonic Adventure 2 Battle, the first Sonic game for a Nintendo console. Adventure 2 received positive reviews, with praise for its gameplay variety, visuals, and music but criticism for its camera, voice acting, and plot. Although reviews of Battle were more mixed, it sold 1.7 million copies worldwide, becoming one of the bestselling GameCube games and the bestselling third-party GameCube game. Following Adventure 2, Sonic became a multiplatform franchise, beginning with Sonic Heroes (2003).
Sonic Adventure 2 introduced Sonic to a wider audience with its GameCube port. It originated characters and elements used in later games; Shadow became one of the most popular Sonic characters and featured in the spin-offs Shadow the Hedgehog (2005) and Shadow Generations (2024). Adventure 2 remains popular among Sonic fans and was rereleased for the PlayStation 3, Xbox 360, and Windows in 2012. Its first level, City Escape, is considered one of the greatest opening stages in a video game. Adventure 2 has been ranked among the best Sonic games, although it has been characterized as divisive, particularly for its emphasis on multiple characters. Its story has been adapted in media including in the anime series Sonic X (2003–2006) and the live-action film Sonic the Hedgehog 3 (2024).
