Sonic is back, and to beat the nefarious Dr. Eggman this time, he will need the assistance of all of his close pals. In Sonic Advance 3, Sonic and Tails are tasked with finding their pals Cream, Knuckles, and Amy and reuniting with them. Join forces with any one of these five characters to unlock extraordinary offensive maneuvers: Amy provides the Piko Piko hammer attack, Knuckles improves your attack power, Sonic boosts your speed, Knuckles increases your attack power, Tails increases your jump power, and Knuckles increases your attack power. Cream allows you to conduct a homing strike. You and up to three other players can compete against each other in various multiplayer modes if you have a Game Boy Advance connection.
