A few months ago, at the hvrev forums at houstonvehicles.com, i suggested that a giant lava map with only transports available for creation should be made in order to teach the long forgotten art of cooperation. and noone made it... so i decided to give it a try.
basically, there are 2 platforms about 2200m away from each other, separated by a large expanse of lava. there are small spires of rock here and there, but not enough to get to the other side by jetpack (or in revmod2, boosting). both bases have a large flag tower, about 100m tall, that has an exposed flag that can be easy to grab if done right. the bases are very simplistic, and very low (you wont fall far to the lava if you manage to get blown off the platform) there is also a dark orangish red haze over everything, and the tops of the towers penetrate the smog to clear blue skies. navigation is easy... its rather flat... but can also be hazardous due to the smog and the obstuctions.
