In the future, technology has moved very far and it is possible to replace almost any part of the body with a mechanical prosthesis, no worse, and in some ways even better than a flesh limb. It is even possible to make backup personality, to recover in a critical case. Due to a critical bug in the new patch, all those who had an eye implant were affected by the emergency loading of the personality. Side effects of this bug include voices in the head and difficulty controlling mechanical limbs.
