Unlockable mission tier 7
You can unlock a 7th set of missions in 'Mission' mode by earning at least 1 star on every other mission available.

Stars
You can unlock having a star by your name in NWFC matches by completing all Grand Prix cups with 1 star or higher. the number of stars that appear by your name in NWFC matches will be determined by the lowest grade you have on any race in Grand Prix mode. For example: If you have 1 star in any Grand Prix cup, but you have 2 stars or higher on all the other cups, one star will still be displayed by your name. If that one star gets pushed up to 2 stars, 2 stars will then appear by your name in all NWFC matches. Although extremely difficult, it is possible to have 3 stars by your name by achieving a 3 star rank on all Grand Prix cups. It is possible albeit very rare.
