Sonic Heroes Cheats

Defeat Metalmadness
As Team Rose, break one of the boxes to get Team Blast. Get close to him in Power or Fly formation on the edge. Use it, then change to Fly formation attack until you are not invincible. Do the same thing again with the other box, then keep attacking in Fly formation close to him. If you get hit, get back on the stage and avoid the rest of his attacks. Get the rings and try again. Eventually he will lose his 100 HP on that side. Then as Team Chaotix, the color of his weak point changes, and it will not be harmed by that formation (blue impervious to speed, red impervious to power, etc.). First, change to Fly formation and get the balloons above you without getting hit. Get in Power formation, get in the canon on the edge, and fire at the weak point. Note: You will not get hurt in the canon. Do this again until it is red and switch to fly. Do the same thing as Team Rose until it turns yellow. Repeat Power formation and Fly formation until he is defeated. You are now in front of Metal Sonic as Team Dark. First, get the level-ups for all three characters. Rouge's is in the air and the rest are in the boxes. Attack him in this order, according to color of weak point: red fly, blue power, and yellow power. Power formation does the most damage. It is recommended that you first get a few extra lives for each team including Sonic's for the next Boss if you have a problem getting balloons.

The Metal Madness part of the Boss is easy, but is the longest. Every time he shoots three rounds of a crystal attack counter with Homing Attack. If he uses missiles, use Thunder Shoot. If he goes down below the clouds, he will throw a ship at you. To counter, punch the ship. His last attack is Chaos Control. This attack is unavoidable and does not do any damage. The only attack that hurts him is Team Blast. To use it, counter the attacks and most of all check your rings; it still decreases like the other Sonic games while in super mode.

Defeating Team Boss
When you fighting a Team Boss use Blue Tornado on them by choosing the Speed Formation for any Team desired.

Robot Carnival: Easy lives for Team Chaotix
When you have many robots, use Team Blast and you will have more than 100 rings because Team Chaotix can get rings from every enemy with their Team Blast.

Playing final stage in story mode
When you complete one of the story modes, go to the challenge screen. Notice that one of the stages is not there. To play this stage you must get all seven Chaos Emeralds. You can get the Chaos Emeralds by playing the stages before you face the Boss. Get the key for that stage and go to the bonus stage. Then, catch the Chaos Emerald before you get to the end of the bonus stage. Once you get the all seven Chaos Emeralds, you can play the final stage. There is only one Chaos Emerald for each set of levels.

Get Metal Charecters in multiplater
To get metal charecters in the multiplayer matches simply choose the event as usual then you'll need to pick the teams. Once you have done that the origonal 1990's loadin screen will come up whilst it loads the level. When its loading hold the X + Triangle buttons down and don't stop holding them until the entire loading process has finished. You should end up with metal charecters on the team you used the cheat with.
