It's description read:
Fly through the caverns to reach the outpost. Watch out for enemy craft, as well as the aliens that inhabit the caverns.
Each part only had three levels so this game only consisted of three levels and Outpost and Outpost 31 should have had six levels each. However on the Jagex site said that Outpost 31 only had three levels.
