a few things I would like to see is more things with cooking, currently i end up just eating most of my stuff raw which I imagine would hurt moral in many cases
electric lighter: this would be a good addition consuming battery power to produce a spark (nice addition to the integrated tool set as well)
better AI: would be nice if things like turrets shot at zombies too and not just me
added occupations: librarian: starts with your choice of 2 books
added occupation: soldier: increased strength (and possible starting equipment)
added guns: nagant, break action shot guns, Muzzle loaders, bassinets
added Bionics: battery charger: consumes your power to recharge a battery
reconnaissance drone: this is based on the helicopter things you can get for your Iphone, comes equipped with a camera and would be great to survey an area (bionic integration to send info directly to your brain/eyes)
the little things: can openers, power system (to power things like battery chargers, stoves, refrigerators ect, ect, ect)
