Rouge and Knuckles

At any point if you cannot seem to find what they are supposed to look for, intentionally die. You will lose all your rings, but in big stages you will find that it is to the most benefit. Note: Make sure that you have plenty of lives.

Security Hall: Fast completion

In this stage you play as Rouge the Bat and are given 5 minutes to complete it. This can prove to be quite difficult. If you have enough lives you can do this trick. If you cannot seem to find the Emeralds, you should die. You will keep the existing Emeralds that you have collected. You will begin at the start of the level and the Emeralds will move to different places. This is the fastest method for completing the level if you are having trouble.

Big the Cat appearance

In Knuckles’ Pumpkin Hill level, go to the one of the train gates. You can see Big the Cat hiding behind the gate, waving to you. You can also see him in the battle against Sonic while playing as Shadow.

The last two sightings of big the Cat

On the very last stage, when you are Tails, when you are on the platform ,in which goes down, Big is hanging on the wall.And when you are Eggman, when you are falling down through the laser beam, Big is standing right there at the end of the tube, in which you are falling in.

Another big sighting

When in hero mode you will play as knuckles to get three keys. go straight over to the machinery room and climb over on the tower and keep climbing around the whole thing eventualy you’ll see big [send by:stephen]

Quickly complete Security Hall stage

In the Security Hall stage you play as Rouge The Bat and are given 5 minutes to complete it. This can be quite difficult. If you have enough lives you can do this trick. If you cannot seem to find the Emeralds, intentionally die. You will keep the existing Emeralds that you have collected. You will begin at the start of the level and the Emeralds will move to different places. This is the fastest method for completing the stage if you are having trouble.

E102 appearance

In Rouge’s Inside the Pyramid stage, one of the robots you blow up is E-102.

Extra time on rouge level

ON the level where rouge must find 3 choas emeralds within 5 minutes. If you find the first 2 and only have about a minute of time left….let rouge die and when you start your next life you’ll still have the 2 emeralds and about 3 and a half minutes on the clock to find the third

Lose The Board On City Chase

When falling to the ground in the first level City Escape, instead of falling on board you can make it so you can fall on foot. Run towards a wall at full speed with spin dash then hit it and have Sonic get knocked down. Right then pause and push Retry and it’ll restart with Sonic on foot instead of on the board in the beginning

Mystic Melody with Eggman and Knuckles

When you are Eggman,go on to your second level, ‘Sand Ocean’,go on the first rotating platfor. Let it turn three fourths way,then use the hovering trick and fly over to an enemy shoting bombs at you,destroy him and get the up-grade,Mystic Melody wich should be right above and in front of you. You need perfect timeing for this. Mystic Melody with Knuckles is like this, you go to his first level wich should be stage two after the movei where Rouge and Knuckles first meet. Anyways, use the wind to get to the upper part of the level, go to the right and you’ll see a sitting statue, go above it and dig in a piture that has an ovel in the middle ,dig in the middle and you’ll find a secret room, Mystic Melody should be there in that room .

Defeating King Boom Boo

In the Hero storyline, only run fast enough so you can see his face. When he starts breathing blue fire, you will have more than enough time to punch the ghost holding the hour glass while he is preoccupied making is wall.

Defeating Shadow

In the Hero storyline, during both Shadow battles you can use the same strategies. Shadow cannot defend against the bounce attack. Instead of trying to catch him off-guard, keep somersaulting at him. This makes the battle easy.

Wild Canyon: Extra dragons and lives

Use the following trick to get a lot of dragons in about ten minutes. At the start of the Wild Canyon level, climb the tall pillar to your right. When you reach the top, get the extra life and glide to the pillar on the other side of the room. Then, glide onto the pillar closest to it and get the Chao box. Enter the ‘wind tunnel’ and when you get to the top, go to your left. Go to one of the first cubes blocked by boxes. Punch the boxes for another extra life, then go to the end of the path. Once there, hit the Chao box, but avoid the animals. Once you get that, go to the path across from the one you that are in. Go all the way down and either kill or ignore the rhinos. Then, drop down into the statue area. Get the Chao box and the dragon, then exit and repeat this as many times as needed.

Sky Rail: Shortcut

There are places in the level where you can jump as Shadow from the rail you are on to a rail you are going past that you normally would not get to until later in the level. This method saves time, and it is fairly easy. Be careful — do not jump to a rail that will take you back, adding time. Additionally, on the last rail, take the rail on the right versus the left. The one on the right slopes straight down to the goal. Also, crouch at the very beginning to go much faster.

Hidden Base: Interesting statue

In the Hidden Base level as Tails, go to the pulley where, at the top, there are five to six Kiki’s throwing bombs at you. In that area is a headless statue of a nude woman, holding her cleavage.

Homing Laser upgrade

To get the Homing Laser upgrade for the Eggwalker, on the first stage of the Dark story line, find a hall blocked by iron containers. Shoot them with your Vulcan cannon (needs to be upgraded first). You will find the homing laser upgrade at the end of the hall.

Glitch:Stuck in wall

As Sonic or Shadow, enter the regular Chao Garden. From the entrance walk right against the wall while pushing against it with your side. If done correctly you will walk into a little groove in the wall. You will do the spin attack even though B was not pressed.
