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.
There is a glitch in the purple gem you can purchase at the market. The purple gem allows you to "change size" in the description, shrinking you down to fit in small areas. However, when using the gem for Sonic you can jump an unlimited amount of times. When you press Jump while holding Activate Gem and repeatedly tap A, your character will act as if he wants to do the homing attack. However, the game will glitch, cancel it out, and allow you to jump as many times as desired while moving in the direction you wish to go. This allows you to get to interesting parts of Soleena or an action stage that you were not meant to access. If you die or find a alternate way to lose the gem, it may be "out of stock" for some time.
Select Multiplayer mode and choose Battle mode. Select Sonic and Silver 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.
Select Sliver from the episode selection menu. Note: This works better if you have completed Sliver's episode. Walk to the part of the pier from where as Tails or Sonic you travel to Wave Ocean. Next to the building should be a barrel with no cover. If desired, go inside. This makes it easier to get Blaze in. After a few attempts of spinning in circles, Blaze should come in. If you are near the edge of the barrel, use Psychokinesis and you should see Silver's head pop out of the barrel. If you have a lot of patience, you can get Blaze to be in the barrel and Sliver on top after fooling around with it.
Select Sonic from the episode selection menu. Note: This works better if you have completed Sonic's episode. Go to the building that is part of the Desert Stage (not the place where the Transportation Mirror is located). On the opposite side of the mirror, there should be a wall. Use the "Sliding" technique to get under the wall. While Sonic is landing on the roof, Sonic should do a sideways spin instead of a normal one. Note: This may not work every time.
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.
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.
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.
