You can play this after starting a new Tournament, bud I recommend going through Amateur first to get your vehicle upgrades and new characters.
It's consists of 7 Maps
2. Ando Prime
3. Malastre (Look for the shortcut at the right side of the map, nearly 7 seconds into the track, use it to be on the top)
4. Scrapper's Run (Beware the second jump, try to slow down on the fall)
5. Mon Gazza
6. Baroonda (Top speed upgrades recommended for a jump)
7. Aquilaris (Top Speed upgrades recommended for some jumps)
Just play naturally through the course, aiming to get first place on every map, if you are in trouble, try playing with a different character/pod racer.
