What do you mean by car frames?
I think he means like empty brush hulls that you can fit wheels, seats and stuff on.
I'd suggest some kind of rocky hill/mountain that you can drive rock-climbers up.
also, I'd say change the skybox. I know it's just me, but that lighting is too gloomy. Same thing with Snabbans Airfield map, I couldn't keep building on it because of the lightning.
Thanks, Pelf. First time I get that wrong
But yeah, ever played Snabbans airfield? There's LIGHTNING EVERYWHERE!
