So I came across a post by JGF (in this thread) about the time turrets on buildings were accidentally allowed, and that reminded me; we should totally add this as a proper feature. I wanted to hear your thoughts on the implementation details, as well as gauge how many people actually want the ability to build turrets on buildings. In any case, I think it makes sense to make a few changes compared to the accidental earlier version: - Only turrets should be allowed on other buildings, as they are small enough that you can't just fit the corner positions onto a building and leave the rest floating. - The turrets are linked to the building below it; destroy the building and the turrets are also destroyed; same goes for recycling (and cancelling recycling). - You can only build on specific buildings; barracks, armoury, refinery.
