In this first game by Atomic Jelly, a nanobot journeys through a human organism to revert the effects of strange illness and a set of unfortunate events that occurred.

Armed with once purely medical equipment that now became a duo of adaptive weapons - the Energy Cannon and the Remedium Sprayer - and able to travel in a fast and agile way with help of an invaluable grapnel, Nano+ can fight pathogens, mutated organisms and deranged nanobots, heal, help his allies and interact with a unique environment.

Nano+ is not alone in hist struggles: the veteran nanobot SuperVisette will guide him through the journey and the last sane nanobots struggling to maintain health and order will also help however they can.
