Sonic Unleashed Cheats

How do you enter the cheat codes in Sonic Unleashed? Do you enter them during gameplay? Before game loads? or at the main screen? I enter all of the cheat codes in their respective order and during the correct gameplay, but nothing shows up. I have read the codes and have them memorized, I just need to know how to enter them in the game. I don't know if you have to press the buttons in the correct pattern or if they all have to be pressed at the same time so that they can work. I began entering the codes slowly and then faster to see if it would change how they are entered into the game, but I tried it during the gameplay itself. I haven't tried any other way, but I want to know first hand if theres' a specific way of entering the codes.

B0ost In Beginning

When sonic starts counting down, when he says "1", press circle to do a boost and gain a boost gauge.

How To Remain Sonic Longer

While in a bonus door you can stay regular sonic by pressing and holding the square button to crouch (you must stay crouched to stay regular sonic). But when you stand up he will he will lock at his hands then he will change into Weresonic.

Wierd Glitch

In a Gaia Gate, go to one of the doors on the sides. Find a light that transforms Sonic into his regular form. After a while, you should see a purple vortex that transforms Sonic back into werehog form. Right at the moment you see the vortex, press and hold the square button. If done correctly, you should still be in Sonic's regular form. When you let go of the square button, Sonic should do something very weird (I'll let you find out on your own)!

Beating Dark Gaia

When you are Gaia Colussus, use triangle at the beginning when Dark Gaia's hands are purple. (The middle part is easy. Just pop 3 eyes with Sonic). Also, when become Super Sonic pop 6 eyes. He will open his true eye (Dark Gaia) and then pop that eye and you've won the game.




Final Adabat Bonus Mission

Collect all art, movies, music and secret document except for the #36 to unlock the adabat final mission.

Sonic Omake Intermission Sequence

Earn an S rank in all the missions to unlock the final mission, then play it and complete it with all the hidden items to unlock the sonic omake sequence.
