What about some ice related machines? Also more to do with electronics would be nice, like crafting generators out of engines and using copper wire for power cords and power outlets, some more permanent lightning would be cool.
A freezing machine, 3x3 room of unbreakable glass with two opposite doors on the sides, a computers in front of it and some dispenser, hack the computer to freeze whatever is inside the room, the dispenser fills whatever you put there with liquid nitrogen.
A particle accelerator, 3x3 worldmap tiles underground, explode it (with c4 or grenades) and it spills liquid nitrogen and randomly generates sparks if the machine is on; every now and then in the corridor, a nitrogen valve (wrench and it spills), electric panels (smash enough of them and the machine turns off for lack of power), a small eletric trycicle to carry stuff and move around, a control panel (can be hacked to turn off the liquid nitrogen, superheat the accelerator if it’s on) that can smashed for a ton of electronic components; it have at least one control rooms on opposite ends one level above, they can turn the machine on and off and sound an alarm if it’s overheating. If it overheats, it starts a countdown (two hours maybe) before it explodes leaving a radioactive crater (like the nuclear missile); maybe also generator rooms, with a source of gas or a huge stock of batteries, and some power outlets, hack console to turn it on, use copper and duct tape to fix the faulty cables around, close circuits and power the lights. We could have an item, power cord, attach like a trap more than one lined up starting at a power outlet powered and the last one becomes a power outlet, get some lamps for said outlets to work like car headlights. (bit offtopic, but talking about car headlights, it would be cool to intall ‘headlights’ in cars facing other directions too).
Vending machines, put a bundle of cash, hack it or smash it to open, lots of food and drinks inside, while locked thing in packages don’t perish inside it, once open deconstruct for electronic components and a rubber hose.
Ice machine, cash or hack it gives dozens of ice cubes, smash if for components and a rubber hose. Hack it to open and get a bettery slot, similar to UPS, unload to retrieve batteries or recharge, put it back, close it and run the machine again.
Emmergency lights, uses the same battery slot as the ice machine, turns on once the room gets dark.
Maybe a machine to make Vaccine shots? Put medical USB on it, get some stuff to mix (using first aid and cooking skills) with a bunch of vitamins, dayquil and nyquil to make various types of vaccine depending on the software.
Maybe a DNA analysis machine too, use syringes/vacutainer to take samples from undead, unload syringe on vial, put vial on machine, put USB on machine, hack and active it, USB gets DNA analysis of (something), take DNA analysis to machine to make Vaccine shots, get stuff to mix and make a special vaccine that upon injected on the body of a zombie have a small chance to turn it back into a survivor.
More off topics:
Ways to restrain without killing: apply rope at a body to tie it, a padlock that allows chains to be used to restrain too, leather belt that can be used to restrain, bed/chair with electronic locks controlled by nearby console, plastic or metallic handcuffs…
Ways to interact with non-hostile woodland animals, like grabbing and carrying the rabbits/cats/dogs - perhaps just don’t allow them to be put inside a bag while alive, and give a random chance for them to get rid of your grip, and reaction level determines whether they struggle (feed them first and they maybe let you grab them, hit them once them try to grab them and they attack or struggle). Perhaps a screen for the pets, similar to the vehicle one, to check their status and equip stuff on them (like strap a bomb to a rabbit, or a fannypack to a cat, or have your dog carry your backpack), maybe even train your dog to do stuff for you (maybe add a new taming skill). Also, horses. And sabertooth. And penguins. And bear cavalry.
When we’ll be able to sex NPCs? We need babies and death by old age to really get this rolling. We also need that command to have them guard a place too. In short, factions.
Damn, I’m going way too off-topic already.
