Sonic Adventure 2: Battle

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.
