Details on four new tracks from the upcoming online DS blockbuster. Read about Yoshi Falls, Luigi's Mansion, Delphino Square and Waluigi Pinball inside...

While the classic courses are grouped under the name "Retro Grand Prix", the new tracks form the "Nitro Grand Prix". It's four cups are named as standard: Mushroom, Flower, Star and Special. The second course of the Mushroom Cup is the all new Yoshi Falls. It's Hawaiian-themed, built at the base of a vast waterfall-filled valley around a giant Yoshi egg and features sheer drops into a watery abyss, two levels, plenty of boost pads and wide but 45-degree angle tracks.

In contrast, the Luigi's Mansion track has tight corridors and plenty of traps to dodge, including swinging chandeliers and rickety staircases. You'll also be going outside the Mansion as well, into the graveyard in the garden where wizened trees come to life and walk across the track!

Found in the Flower Cup is the Delphino Square course, which will look fairly familiar to players of Mario Sunshine. Through the town square the track winds, before you're racing through the harbour and boosting over an open drawbridge to the finish.

The track after that is Waluigi Pinball, set inside a giant pinball table complete complete with tumbling steel balls and high-speed tunnels. Apparently, it's one of the best tracks in the game, and with only about a month to go until Mario Kart DS' release, it won't be long before you'll be playing it!
