Umm lets see...
Your right leg, left arm, and right eye.
Let's test it.
Hold out your left and say "Initiate Scan"
A HUD should appear in your right eye, while your arm scans the room.
Yeah I know right?
It's not bad once you get used to them.
Now you can get upgrades to them, like my left arm doubling as a rifle, but don't over do it.
Using to many functions at once will overload them.
Well, for the arm, I was thinking something like a long knife or blade that can pop out on the bottom of the forearm, and a small tranquilizer gun that pops out on the top. That and advanced target acquisition for the eye. Maybe radar?
Sure sure.
*starts installing blade and tranq gun in arm*
Now for your eye, I can't detach it, so this might sting a bit.
*inserts micro lance, starts installing radar and advance HUD*
Of course it is.
How else am I going to calibrate your optic nerve to detect the echo location involved in Radar?
Now hold still, this is where you might pass out.
*injects nano tubes into optic nerves, then replaces iris with auto locking and target acquisition system*
*finishes calibrating systems*
*runs systems check*
Alright done! Not so bad was it-
*sees has long since passed out*
Maybe I should have used anesthesia?
Ah well.
*leaves food and coffee on hospital tray*
See you when you get back bud.
*leaves room*
*wakes up*
Ow. -blam!-. Phantom whe-?
*sees tray of food, starts eating as fast as possible*
This is good. Really good.
*bionic arm knocks over coffee*
SHIT.
