Many of these hints & tips are answers to questions I received in email.
Thanks to everyone who helped build this list!
The drop-ship is there, but the visibility sucks so you have to walk a bit to see it. Go to the farthest NAV point as instructed and then head DUE NORTH. Zoom your view to max and pan back and forth until you see the horizon change. Don't try and use the satellite.
This level is very difficult. I had to cheat. I used PALEX to get rid of some of the mechs so I could make it thru.
