Sonic Advance 3 Features:
2-character team gameplay
CUSTOMIZABLE TEAMS!
Giant rings (for the special stage?)
Keys (for the special stage?)
You can pick up your partner
4 known playable characters (and hopefully more – the Chaotix and Rouge would be great)
4 known zones – Route 99, Sunset Hill, and 2 unnamed zones
A zone “map” level where you can find entrances to hidden stages
2-player cooperative mode where both players explore different parts of a level
Notice that the characters are not defined by formation – Tails and Cream are on the same team in 1 shot.
You don’t actually play as both characters, but your choice of partner affects where you can go and what your abilities are.
Thanks to Project Blue Gale for finding this.
