I was making a battlefield for my 'Drow Wars' module and I thought this area was entertaining to watch. Basically, you can navigate through a battlefield while two armies of npc's fight it out. The catapult on the human side is interactive, whereas the Drow one shoots randomly.
I'm sorry. I didn't realize custom blueprints didn't transfer with the area export/import. As consequence, badgers were re-spawning as opposed to the soldiers. This latest mod and zip file contains the necessary erf's along with an item decay script.
