Nanotechnology, shortened to "nanotech", is the study of the controlling of matter on an atomic and molecular scale. Generally nanotechnology deals with structures sized 100 nanometers or smaller in at least one dimension, and involves developing materials or devices within that size.
Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nano scale to investigating whether we can directly control matter on the atomic scale.
The Ultor Corporation first started experimenting with nanotechnology circa 2011, when their intention to start mines on Mars became a developing project. The company used ordinary civilians as test subjects, and many of them did not survive its effects, which triggered Ultor to bury the bodies to prevent its project from becoming known to the public.
In 2075, when the Ultor Corporation had already colonized Mars, nanotechnology was being successfully created by Ultor scientist Axel Capek. His inventions eventually led to the creation of the Nano Forge.
Five years later, the Commonwealth was using nanotechnology to create "supersoldiers" for use in their own army as the Nanotech Enhanced Forces. Victor Sopot had 2,000 of these soldiers created, but after fearing their immense power, he ordered them to be hunted and eliminated. Only six of the supersoldiers avoided elimination: a squad of soldiers consisting of Crate Molov, Alias, Shrike, Tangier, Repta and Quill.
In 2125, during the Second Martian Revolution, Capek's Nano Forge was found by Alec Mason, a Red Faction guerrilla. The Red Faction later used salvage to create the Nano Rifle, which could destroy any form of matter.
The Nano Forge was used to make even more weapons, such as the XNG-5000 grenade launcher, before it was passed down to Darius Mason, Alec's grandson and a technician, who created various upgrades to the device to use the Nano Forge during combat.
