Snowtroopers, also known as cold assault stormtroopers, were Imperial stormtroopers trained to operate in arctic climates. Some snowtroopers were deployed under Death Squadron's Blizzard Force, as well as other arctic forces.
The snowtroopers were the successors of the clone cold assault troopers and the Galactic Marines under Clone Commanders Keller and Bacara, respectively, during the Clone Wars.
The hologram image of the AT-AT is a recreation of the "Empire Strikes Back" game from Hasbro for Atari and Intellivision (1982).
