Re: Vehicles (Star Wing ftw!) and Prison map
That was the original design for the Tauntauns as drawn by Ralph McQuarrie mate.
As for Tauntauns in game it is unlikely, but if we could have them it wouldn't be silly at all, you'd use them for recon/scouting, you'd have a much lower profile than if you were using a vehicle, and also you'd get there a lot quicker than on foot.
Yea but what is there to scout on Hoth man?
The ATATs are 4 stories tall... you don't have to look hard across a barren ice plain to see em
