Lets talk about Sonic Rush Adventure NDS

Sonic returns to the Nintendo DS in an all-new frantic adventure complete
with dizzying dives, near vertical curves and brain twisting loops. Sonic Rush
Adventure will deliver the dual screen action fans loved in Sonic Rush™, as well
as a new high seas adventure where Sonic clashes with ruthless pirates. As
Sonic, players will set off from Windmill Village to blast through seven
action-packed and widely diverse levels that continue the great 2D gameplay
experience from the original Sonic Rush.

Players will speed through action stages to uncover valuable items and
materials which allow Tails to build new ships to help Sonic track down the
villainous pirates. With a fleet of up to five ships, including a submarine,
water bike, and hovercraft, players will use the touch screen technology in
exciting new ways, controlling their ships as they race across the ocean
gathering rings, performing tricks, and torching pirate ships in fierce
ship-to-ship battles. At the end of each level, players will test their skills
in epic 3D boss battles spanning both screens, including the ultimate showdown
with the evil pirate, Captain Whisker.

In Sonic Rush Adventure, players will bounce, fly, swing, ride and run
through grand environments that will include lust forests, an ominous ghost
ship, snow covered mountains, pirate villages and a vast underwater sea cave.
Along the way, players will do battle with a variety of enemy characters
including robots, skeleton warriors, pterodactyls, and a robotic triceratops.
