Rumble Launcher

The Rumble Launcher is Neutral Chao special moves in Sonic Adventure 2 and Sonic Adventure 2: Battle. When using this technique, the user fires a missile barrage from his mech.

Description
When performing Rumble Launcher, the user folds out a rectangular missile launcher on the back of their respective mech and fires a barrage of missiles into the air which will then pinpoint and rain down on the foe. In gameplay, the Rumble Launcher is a powerful move which automatically homes in on the opponent and the missiles are fast enough to catch up to the opponent when in run. Should the missiles take too long to reach their target though, they will eventually disappear. Rumble Launcher can only be performed by the player by playing as Neutral Chao in the games' two-player mode. To use it, the player must press // after collecting 40 Rings. To use it again, the player has to collect another 40 Rings.

Trivia

 * The Rumble Launcher appears once the player collects forty rings and return inside the machine once used.
