Hang Castle

Hang Castle is a medium-hard level in Sonic Heroes. It takes place in a haunted castle. This level is the eleventh in the game, before Mystic Mansion and after the second Rival Team fight.

Description
Hang Castle is one of only two stages that contain the mysterious gravity inversion switch. Its effect in this stage is limited to flipping the stage upside down (though through hacking is revealed to be teleporting characters to areas identical to an upside-down version of the original). The castle is also filled with booby traps, such as the ghosts that appear, as well as the invisible walkways. The Egg Magician / Egg Bishop enemy also appears here. This robot has two faces with different personalities: on the kind-looking red face, it casts a spell to heal all robots nearby, including itself; the sinister blue face can curse the ground to suck rings from anyone unlucky enough to stumble into it. It will not flip faces of its own accord, but the player can force it do so by creating a tornado in Speed Formation. Because of their unique Light Dash ability, Teams Sonic and Dark can find trails of rings in this level.

Story
After the 2nd team battle, Team Sonic infiltrates the castle to find Eggman and Shadow. Team Dark enters the castle while Shadow ponders over his identity and what exactly the blue hedgehog is. Team Rose finds the haunted castle and continue after Amy reminds Cream and Big of Chocola and Froggy. Team Chaotix are off to find the keys located in the castle (presumably to get into Mystic Mansion).

Trivia

 * If the Eggman statue is looked at while upside down, a statue of Neo Metal Sonic can be seen, foreshadowing that Eggman isn't the real villain after all.
 * This is the only stage in Sonic Heroes to have two theme songs: one for when the castle is right-side up and another one for when it's upside down.
