Very cool! Takes place entirely in a desert except for a few spots here and there. No real buildings anywhere and the one tree we see in the whole film doesn't survive (not that anyone wanted to destroy it, but hey, y'know?). Lots and lots of specialized vehicles and as no one wanted to fall off or get left behind, it was kind of like it was taking place at sea, with a few islands every now and then. And yes, I've seen all three of the earlier episodes.
