What if limbs could be modded to fit attachments like tat guns (mentioned in the hi-tech thread), weapons, or proggies? The item is stored in the arm and a command would morph the appendage to expose the item for use in place of the hand. Negatives could be include reduced chance to grapple/resist grapple when the limb is morphed into something other than a hand. Or something like that.
This could add some use to limbs, carrying an item inside safely for on the go use without a sheath or bag, etc. On the other hand, it makes the limb a target for thieves and muggers. What do they have in there? Paydata on an quick draw e-note? Expensive gun with all the good mods?
Which brings me to the next part. Live ripping. I picture limbs as socketed items within a recieving prosthetic part. Male socket to female socket kind of thing. So limbs could be forcibly removed by a skilled ripper without the victim being dead.
All on all it's some fun thoughts inspired by a member on the boards and Alita:Battle Angel.
