So far I've found 2
Outpost 7 White/Black: The bridge, this is supposed to be one yes, no?
De Konstruct Black: Right hand side of the track with no mag strip, ship floats up to a higher section.
Anymore? I'm still waiting for the shortcut thats actually a shortcut. So far the two above are just a waste of time seemingly only cutting your chances of winning if you use them.
Remember Anulpha Pass, thats a shortcut, so what went wrong?
