Thank you for the feed back jb
The outside looks really empty as you say, but I have some optimization problems with vegetation. I have replaced all the grass staticmeshes with true decolayers (I had problems with paiting decolayers, but now its ok), so the map runs a little smoother now.
I am adding small walls around the palace, only for decorating, with trees and bushes, some statues and banners...
Maybe a big defence wall ? just a try, but am not sure I'll do it
Concernig Z play, it is possible at the moment to climb on the first roof, there is an open window over the balcony (there you should find the trap trigger

), but bots can not use it^^
I will add jumpers to allow bots (and players on an easier way) to access this place ; maybe I will add some mini healthpack / armor shards pick up there too
By the way the current release is downloadable at mapraider's too :
(link removed, new version available, see below)
I'll keep you informed for the next release (very soon coming)
Be excessive.
