Defeating big enemies faster

When facing an enemy that requires more than one hit, then 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 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.

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

Extras menu

Successfully complete Sonic, Shadow, or Silver's Story mode 100% to unlock the "Extras" option at the main menu with "Audio Room" and "Theater Room" options.

Float into the air

When in Soleona, go on top of a metal box in the military base portion of the map. Stand on top and keep tapping X. If done correctly, you will start going into the air. The longer you tap X, the higher you will go.

Free mode

Get an "S" rank on all of Sonic's, Shadow's, and Silver's levels, Bosses, and town missions.

Go outside boundaries when fighting Silver

Play as Sonic in Story or Trial mode. Select the Silver Boss battle. Get as many rings as possible (fifteen). Then, go to the alley in the corner. Try to get as far into the corner as possible. When Silver uses his levitation technique, try to get back in the corner. Silver will try to use the levitation technique again. The rings will be behind you. You should be able to collect the rings before hitting the wall and dieting. Then when you hit the wall, try to collect your rings. You will then go outside the level's boundary. You will be able to walk on invisible bridges and hit other invisible things. Silver might even also get out of the level boundary and throw you out of Soleona and you will keep flying forever.

Have Blaze in barrel

Select Sliver from the Episode selection menu. Note: This works better if you have completed Sliver's mode. 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.

Last Episode

Complete Sonic's Episode, Silver's Episode, and Shadow's Episode.

Longer jumps with Silver

Jump with Silver by pressing A, then press the same button again while in mid-air. This makes Silver float around. When floating in mid-air, tap A while moving in any direction instead of holding the button down. This will make Silver jump further.

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. When he is frozen he appears very small.

Play as Shadow The Hedgehog

Successfully complete Crisis City as Sonic.

Play as Silver The Hedgehog

Win the Silver The Hedgehog Boss battle as Sonic.

Sideways jump

Select Sonic from the Episode selection menu. Note: this works better if you have completed Sonic's part. 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.

Unlimited jump

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 are able to jump infinitely. 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 glitches, cancels it out, and allows 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 will be "out of stock" for some time.

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.

Use the following trick to go faster in Super Speed area. Hold the Analog-stick Up when you use a Light Dash on a line of rings and keep it held. Sonic should now be running with his hands behind his back and be moving much faster than usual. The effect lasts until you release the Analog-stick or crash.
