Sonic Adventure/Sonic the Hedgehog

Action Stage goal
Collect three fragments of the Master Emerald hidden somewhere in the level.

Unique Actions

 * Gliding jump: Press and hold A in mid-jump. Use Neutral to maneuver Knuckles during a gliding jump.  Attack using the gliding jump by hitting enemies with Knuckles's fists. (Hitting with any other body part will cause Knuckles to take damage.) Release A to cause Knuckles to drop (it is possible to revive the glide by pressing and holding A again).
 * Climbing: Knuckles will automatically begin to climb once he grasps a wall during a gliding jump. To do this, execute a glide jump and aim him at a wall you wish to climb.  After he has grabbed the wall, use Neutral to maneuver him and press A to jump.  This will not work on all surfaces, however.
 * Punch attack: B or X. Execute two punches in rapid succession to have Knuckles execute a third, more powerful "dash punch".

Level up items

 * Shovel Claw: Allows Knuckles to dig.
