Getting Super Sonic in 2-Player Sonic Adventure 2: Battle

Game clarification: "Adventure Battle" likely means Sonic Adventure 2: Battle (GameCube, 2002; also on Xbox 360/PS3/PC via port).

Unlock Super Sonic (Both 1P & 2P)

1. Collect all 7 Chaos Emeralds in Hero Story (Sonic, Tails, Knuckles).
2. Collect all 7 Chaos Emeralds in Dark Story (Shadow, Rouge, Eggman).
3. Final Story unlocks → beat Finalhazard (Biolizard) as Super Sonic & Super Shadow.

2-Player Mode Specifics

• Race / Battle modes: After unlocking Final Story, Super Sonic & Super Shadow are selectable in 2P Versus (Kart Race, Chao Race, Battle).
• Requirement: Both players must have completed the above on their memory cards (or same file).
• Transform: In versus, collect 50 rings → press Jump twice (or designated button) to go Super.

No separate "Adventure Battle" game exists. The 2P versus is in SA2: Battle.
