Planning the game usually goes beyond the next big update. So this one is a concept for abandoned bunkers that will be introduced (hopefully) in 0.9v along with some of their "residents". Imagine this as setting up the scenery for more diverse gameplay. http://pbs.twimg.com/media/Fs4P-RnWcAEG2na.jpg
Bunkers will be split into abandoned/destroyed and operational/active ones. The active ones will be controlled by TEC1 personnel (AI), and abandoned will be, well, source of many mysteries and loot just waiting to be found. Easy peasy!
