Would it be possible to have a bionic that contains artifacts? Like you install it, it sits there.
Then you can put an artifact into it, its effects are contained and thus shielded away from you and your surroundings. Containing would require alot of power, but in turn the bionic could feed the artifact power and “unleash” the artifact on command.
A GPS bionic that reveals your map much better than a binocular would be awesome too.
A bionic that protects you against radiation would also be rather nice.
A bionic frigde would also be really cool. Install it, store perishable foods, jackshit happens to them.
A set of robotic arms would be robust as fuck, not useable in combat but perhaps make driving and shooting much easier? Give a boost in dexterity?
A combat medic bionic would also be really cool, like an internal medic drone. It patches you up while you are fighting! Administer painkillers in your inventory appropiate for the level of pain and injruies. Activating it would sedate you and fix broken limbs. It would require special catrigdes you can craft with high first aid, cooking and electronics skill or find in pawn stores, hospitals and labs.
