I'd love to see this as a game! (preferably Switch, PC, Mobile, and PlayStation)
These characters were inspired by other things. Also it takes place in an abandoned facility in a part of Germany that speaks English and German.
Buildings include the main building which has the mess hall and dorm rooms on the first floor, and more dorms taking up half of the second floor, the armory and testing zone are also on the second floor. The third floor of the main building is mostly just storage, a few nursery and daycare rooms scattered about. There's also the other buildings, usually only two floors high, very few are one floor. The other buildings include the lab, smithy, storage sheds, and the boxing zone. (you can add more buildings just please include the ones I listed.)
