How to beat Silver:
When you fight Silver as 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?" and do a homing attack on him. Run away again until you hear "How bout this?" again and do another homing attack again. Repeat this until he has been defeated.

How to beat 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. Then, just use all three to survive the blows of lasers, and continuously attack.

Mini Sonic:
Select multi-player mode and choose Battle mode. Select Silver and Sonic and go to any level. Get to the first checkpoint and have Sonic fall and appear at the checkpoint. However, do not move him. Then, make Silver fall and appear at the checkpoint. Just when Silver appears, freeze Sonic (RT). When he is frozen he appears very small.

Very fast Sonic:
In multi-player 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 till you respawn. When you respawn, deactivate the gem. You will now run ten times faster than normal. Also, the time will automatically be slow.
