Sonic Adventure 2

Sonic Adventure 2 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 exploration-based treasure hunting 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, rap and orchestral arrangements, and features several metal singers.
