Each piece could be spawned 30 times at the moment. Each new Buildtime you get 5 more pieces each. At first the limit was set on 20 each, but that seemed not enough for this map.
The Skybox is much higher in this version, so you could throw your nades and pieces as high as possible if you want.

But I restricted the map at same level as the walls with a "player clip", so no one is able to look over the walls.
And thx for reply!
