Sonic Adventure/Sonic/Sky Chase: Act I

In addition to the action stages that you played, the game offers some Sub-Games playable. You will encounter them in the story from time to time.

The first sub-game of the game (and the only one to have two players going on full force) is SKY CHASE ACT 1. In this, you maneuver the Tornado to do an air assault on the Egg Carrier. It's basically simple to do, once you get the hang of the controls. For the GameCube version of the game, they are as follows:

Use Control Stick for Airplane Maneuvers/Target Lock-on Device. Press either the A Button, B Button, or X Button for Rapid Fire Gun. Press and Hold either the A Button, B Button, or X Button while aiming the target lock-on device for Missile Lock-On, and release either the A Button, B Button, or X Button after Lock-On for a Homing Missile.

After the first try, Sonic and Tails are shot by the cannon from the Egg Carrier, and the both of them are separated. Sonic will end up near Emerald Coast in Station Square.
