Sonic Rush (DS)

Altitude Limit Act 2: Special Gimmick
Run to the right to see a spring that sends you into another spring which in turn makes you end up on a platform that has parachute. When the parachute goes up and unfolds, go to the left instead of the right and grind the rail until you see the Special Gimmick.

Zone 6: Light blue
Zone 7: Purple

Completing the Final Zone
When running up the robot's arm you must stop and crouch at the low point between the forearm and the shoulder. This will prevent you from flying off once he waves his arm.

Damage and Rings
When you get hit by an enemy your will fly every where like all sonic games. However, the more you get hit the higher your rings fly thus making them harder to get. This normallys happens in boss battles, but it also effects in in a zone.

Dead Line Act 2
Platform: Nintendo DS

This is the level with the most rings in the game. If you can find the Ring Magnet power-up, you can probably gain at least 300 rings.

Dead Line Special Stage
Where there a bunch of spikeballs, instead of trying to get all of the rings, just stay on the path that has the ring with the '5' in it. If you try to get all of the rings, you will get hit.

Defeating Eggman And Eggman Nega
When you are playing the Final Zone with Super Sonic, Eggman Nega will shoot laser beams at you for about one minute. You will see red rocks floating. Get those if you need extra rings. However when Nega comes up to you, he will raise his left arm. This means that he will shoot little bombs that shoot out laser beams. Press A or B to boost and hit them towards Nega's face. Repeat this three more times and he will be defeated. With Burning Blaze, you must face off against Eggman. He will do everything Nega did, but half a minute longer. He will also create a Black Hole that traps you in one place, while taking all of the rings. He will continue this for 30 seconds. To hit him, hold A to charge your Fire Blast, and make sure you are correctly aiming at his head. The Fire Blast also consumes rings. Continue the Fire Blast three more times and he will be defeated.

Defeating The Final Boss
The first two times the final Boss rams into the wall on Final Zone, Unknown, it does not do anything to you. The third time, you must hit the Boss or the wall will snap in half and you will fall, lose all of your rings, and die.

Easier Special Stages - Pause Method
This is really good for Special Stages. When you're in a special stage, and you have to navigate around lots of bombs, pause the game, and then place the stylus where you want sonic to go next. When you unpause, he will zip to that location.
