Tornado Defense

Tornado Defense Act is a mini-game from Sonic Unleashed, played from the point of Sonic whilst riding on Tails' Tornado aircraft. Your objective is to fight off enemy aircrafts as they attack you, similar to Sky Chase. You must fight the boss Egg Cauldron at the end of this level.

Act I
At this point in the game, Sonic and Tails must head to Spagonia to meet up with Professor Pickle. They, however, wouldn't have been able to get to the continent, due to the fact that the planet was broken at the time. They decided to take the Tornado on a short flight to said continet. They, however, were attacked by Eggman's robot fleet in an attempt to cross the border to Spagonia.

Act II
At this point in the game, Sonic and Tails are en route to Eggmanland for the final battle. As one might predict, they ecountered Eggman's robot fleet once they entered the airspace.

Objective
You need to shoot down Eggman's robots as thay fly towrd you using the button combonations listed on the screen. If you press the right butons, the Tornado will shoot a projectile at the offending aircraft. If you simply mash all of the buttons, the Tornado will lose energy and be unable to fire any more projectiles for a second or two. The Tornado has a health bar, labeled as Shield. There are three types of enimies;


 * Regular robots- 1 hit to destroy, adds to score.
 * Gold robots- 3 hits to destroy, adds extra points.
 * Blue robots- 1 hit to destroy, raises energy.

Trivia

 * This mini-game is skipped entirely in the Wii and PS2 versions of the game.
 * It is possible to replay the first act in Spagonia's Entrance stage at night by using attacks on switches to unlock a door to a courtyard where there is an act entrance for stage 1.
