[MOD HELP / REQUEST] Four arms

[S4NDBE4R]

Hey, just curious if anyone has ventured down this road, adding additional arms? I've been messing with the code for days now not getting anywhere. What I'm trying to do is get a four armed person. Be it organic arms that they start with (tougher of the two) or if its just a prosthetic limb you can buy and bill your colonist to receive. Once that's accomplished, getting them to hold another weapon would be nice. Heck, I'd be happy with just 180% (all four arms being robotic) efficiency buff at the moment.
