Sonic Adventure 2: Battle Walkthroughs and Guides
Sonic Adventure 2: Battle is a 2001 platform game developed by Sonic Team USA and published by Sega. It marks the final Sonic the Hedgehog game after Sega discontinued the console.
The game features two "good vs evil" stories: On the good side, Sonic the Hedgehog, Miles "Tails" Prower, and Knuckles the Echidna attempt to save the world. While on the evil side, Shadow the Hedgehog, Doctor Eggman, and Rouge the Bat attempt to conquer it.
The game also has possibly my favorite one-shot "expansion" in any video game: "Chao". Chao are adorable baby-like creatures that you can raise in several gardens and train them to race, do karate, evolve, and much more.
