These suggestions are a little far-fetched and are intended for the further developpement of the Standalone. Those are the things that I would want to be added for making bases. I think that items such fencing, barbed wire, metal panes, poles, ladders, locking systems, batteries/electrical generators, lights, gates/doors, and electrical wiring would be useful for making bases. The fencing would be rolled up and can be arranged between poles. Barbed wire can be used as a barricade or to prevent people from using a ladder to leap over the fencing. Metal panes can be made from salvaging scap metal and can be used as a barricade or to make walls. Ladders could be used to go over obstacles (maybe be used to get on top of small buildings) or can be used to access down or up vertical obstacles(underground or elevated bases?). Locking systems can be found or crafted from metal and wiring. They could vary from mechanical ones or electronic ones. The mechanical version would be built from scrap metal and could be picklocked using a kit. The electrical one would be made by electrical wiring and scrap metal where the combination could be a word/number. The locks would be used to lock gates and doors. Batteries and generators could be used to power lights or charge whatever electronic item. The generator would consume fuel and the batteries would be scavenged. Lights would be a loot item and can be placed on poles or walls. They would be powered by generators/betteries/solar panels. They can be used for lighting indoors or placed on top of poles. Gates/Doors would be used as a mean of access into bases and could be locked. Electrical wiring could be used to connect batteries/genrators to elctrical items. We should be given the possibilty to build above ground, on the ground or below ground. We could use trenches and digging tools to fortify and create our bases.
