Heh those are some good ideas, but I can't add stuff such as power lines and lights because this building, it's an abandoned soviet time apartment building, basically as the soviet armies went from location to location, they would build apartments like this, for short stay, but they left a lot of them unfinished, that's what it's based on. It was never taken to the point where it had electricity or water pipes or anything of the kind, so it wouldn't have any lights... and I'm basing the map in Europe in an area that has almost no mountains, I actually tried to make it as flat as possible but that led to the landscape just cutting off
...and where you placed the car, that's the skybox
I already released the map:

Edit: Oh and it's a deathrun map, so no cover, and the players jump around the insides of the buildings till they reach the top... so that kinda makes it worse since they can see out in the open from the roof
