3 into 1
You start on 3 different altitudes.
Build up enough to get 2 more stations working, then find the ‘hidden’ tunnels you need to get between altitudes.
Although spotting where the tunnels should be placed is easy enough, you’ll need to get enough cash and have a leap of faith that they are connected and not just some ruse!
50 minutes, plus the 4 tunnels, plus the ‘gotcha’ will give you all 5 stars.
