Sonic Advance 3 for Nintendo Game Boy Advance
The third game in the GBA's Sonic Advance series is one that requires teamwork, between the blue hedgehog and his familiar friends. Dr. Eggman has a new plan to take over the world -- by breaking it into seven conquerable parts -- and he must be stopped before it's too late. The only way to do this is for two Sonic game heroes to combine their powers and work together to retrieve seven missing chaos emeralds. Sonic Advance 3 features five of the series' favorite characters: Sonic the Hedgehog, Tails, Knuckles, Amy, and Cream. Players choose which hero they will control, and then choose a second, AI-controlled character to join their team. This "partner system" unleashes new abilities in the chosen characters, and each different partnership presents the player with a unique set of special powers to help them overcome Eggman's vicious robots. In addition to the single-player storyline, Sonic Advance 3 allows up to four cartridge-equipped GBA players to link together, and enter into a variety of two-on-two multiplayer battles.
