Silver's Theme (Dreams of An Absolution): Silver's Episode
Sonic's Theme (His World): Sonic's Episode
Very fast Sonic
In Multiplayer mode in any level or match, equip the Red Gem on Sonic, activate it and hold it, then die. While still holding the activation button, wait until you respawn. When you respawn, deactivate the gem. You will now run much faster than normal and the time will automatically be slow.
Longer jumps with Silver
Jump with Silver by pressing X, then press X again while in mid-air. This makes Silver float around. When floating in mid-air, tap X while moving in any direction instead of holding the button down to make Silver jump further.
Defeating big enemies faster
When facing an enemy that requires more than one hit, use your Homing Attack on it then use your Bounce Attack. Note: You must first have the Bounce Bracelet.
Defeating Silver
When you fight Silver with Sonic, first do a slide move into him as he is falling from the sky. Then, collect a ring and run around until you hear "How bout this?", then do a homing attack on him. Run away again until you hear "How bout this?" again. then do a homing attack again. Repeat this until he is defeated.
Defeating Solaris
First, use Silver to weaken him until his first arm guard falls off. Then, switch to Shadow and hit him with the beams until his second arm guard falls off. Next, use Sonic to defeat the rest of his first form. Finally, use all three to survive the blows of lasers, and continuously attack.
