Yes, the Bunker, ala StarCraft - basicly, a small, fortified structure: Size - 1/4 size of an NF armory Hexagonal in design to allow for 6 viewholes that are easy to shoot OUT of, but hard to shoot IN to (angled perhaps?). Has an ammo crate. Cannot have turrets built inside. High HP, long build time. Maybe 200 resources? Perhaps make the BE one round and shiny, and the NF one hexagonal and drab? Main idea here is to have a non-automated defensive fortification.
