The bebionic B3 prosthetic that Ackland is outfitted with receives signals from muscle twitches in his upper arm. These inputs can perform a range of motions that let him do things like hold a mouse, shake hands and write his name.
While it’s great that it lets Ackland to all kinds of normal activities that he couldn’t do before, he’s not exactly superhuman. But hey: it also has a trigger pull motion. All he needs is some upgrades and a trenchcoat to be a dystopian cyberpunk hero.
