Following their conquest of the galaxy circa 3636 BBY, the Eternal Empire, hailing from the planet Zakuul, constructed a shield bunker. This bunker was situated on the western border of the Southern Snowdrift Hills, which forms a part of the Clabburn Tundra on the planet Hoth. Its purpose was to provide support to the Star Fortress positioned in geosynchronous orbit above it. Under the command of ZK-294A, a distinguished Skytrooper, the bunker, along with its deflector shield generator, was fortified with formidable defensive structures, walkers, and Eternal Empire troopers. Approximately around 3630 BBY, the Outlander, who was the head of an Alliance opposing Zakuul, united the local resistance against the Eternal Empire. They orchestrated an assault on the bunker, which then enabled the Outlander and the Arcona named Hemdil Tre to penetrate and obliterate the bunker, thereby rendering the Star Fortress vulnerable.
The Hoth shield bunker was initially featured in the video game Star Wars: The Old Republic within the Knights of the Fallen Empire digital expansion, which was released in 2015.
