The PNG-WIN MKII improves upon the original MK I, and is designed for unmanned exploration of arctic regions and similar environments, and is mostly utilized by the Royal Star Fleet.

The PNG-WIN MKII features a liquid nitrogen cooling and insulation system, to both maintain the optimum temperature for its components and processors to function, but also to stop it melting its surroundings.

The plating is designed to blend in with arctic environments, but can be changed to adapt to various environments.

The PNG-WIN MKII uses four different optical sensors, the large red one is designed to detect visible light and IR emissions, whilst the three other green sensors are able to detect large ranges of EM waves, the range each one can detect can be adjusted by swapping the filter, the standard filter being green.

The unit on its back is used for mounting flight units, meaning the PNG-WIN MKII can be used in deep space.

The crystal core in the chest of the PNG-WIN MKII is the central processing unit, know to RSF engineers as "the brain"
