This map REALLY reminded me of Emperor: Battle for Dune. Fremen? Check. Sandworm? Check. Corliosis storms? Check. Tanks and sandbikes? Check. Flame throwers? Check.
Now if only I had some of those Carry-Alls I could win this one!
I'll try some of the stuff you guys suggested. I guess it didn't help that I wasted a few airstrikes trying to kill the Jawas before I remembered that they were on my side.
