I've done bigger.
except not building - every time I do something someone griefs it.
I hate this map.
Those trees, hills and buildings always gets in my way and provide plenty of cover for spawn campers.
So I broke the map.
It's two separate times, but if I can combine them... it would be epic.
First time:

Second time:

both times, the only thing left undestroyed was the hill with 3 trees on it and the stairs.
The second time I also flattened the area where the intel was so fought over. the landscape got in my way.


I prefer doing this over building. Why? you can't grief it. I don't see how anyone can grief a hole in the ground!
