Sonic Rush Adventure [DS]

Gameplay

As Sonic, the player begins each adventure from Windmill Village on Southern Island. Bring up the Sea Chart, you have to plot your route using the stylus. After plotting the desired route, the character begins to race to one of the seven main islands using one of the four ships, a waterbike named Wave Cyclone, a sailboat named Ocean Tornado, a hovercraft named Aqua Blast, and a submarine named Deep Typhoon. On the Wave Cyclone, Sonic can collect rings and perform tricks to fill up a Boost Gauge. When Sonic uses the boost, the waterbike speeds up and becomes temporarily invincible until the Boost Gauge runs out. While using the Ocean Tornado sailboat, you can shoot enemies and rings with either bullets, cannonballs, or a flamethrower. Each varies in strength and clip size before reloading. Sailing in the Aqua Blast is roughly similar to using the waterbike, however there are no ramps, and holding the stylus down charges up a laser which is fired by releasing it. Using the Deep Typhoon submarine involves tapping (sometimes sliding) rhythmically on enemies and powerups to fire missiles at them.
