Opps repeated myself a bit there...
Anyways, haven't started on the trees yet - just working out a way to make it look like they go on forever using a portal sky in combination with "real" trees in forground.
Am currently woking on getting all the major structures in place, then will populate the forest with trees and appropraite foliage.
Red glowy thing on top of bunker and in generator room are CONTROL POINTS - like Battlefront, that you have to capture. Each one is a Siege Objective that once captured, will allow your team to spawn there.
Generator room and generator control room originally modeled by SunBurn for me. (With considerable fixing by me - still have to fix those control panels too).
