Ģ077 represents the pinnacle of Power Armor technology, with units capable of cutting a swath through the Chinese forces. In 2074, Power Armor was deployed on the Chinese mainland, though the units did not see as much success due to heavier resistance. While China rushed to create its own Power Armor, it proved inferior to those made by West-Tek. China soon invades Alaska, and the Power Armor is deployed in 2067, proving extremely effective in battle. The fusion cells worsened relations with China, which was already facing an energy crisis due to over-dependence on fossil fuels.

From 2065 to 2067, several failed prototypes were created, though this research led to the creation of a compact fusion cell. Within the Fallout universe, Power Armor began development in 2065, in response for the need for a 'walking tank' for the United States mechanized cavalry. In Fallout 4, Power Armor was notably more heavily integrated into gameplay, with suits becoming customizable, interactable objects in the game world that the player climbs into rather than typical clothing, and requiring fusion cores to use.

Power Armor has been called an iconic aspect of Fallout, and has featured as an item in every game in the series. It not only allows for protection from enemy fire but enables the wearer to carry extremely heavy weapons and other objects with ease. In the fictional lore of the series, it was developed before the Great War, a devastating nuclear conflict, by a group of United States defense contractors called West Tek.

Power Armor, also referred to as powered combat infantry armor, is a type of powered exoskeleton that appears in the post-apocalyptic Fallout video game franchise. Interplay Entertainment, Bethesda Softworks A Power Armor replica as seen in Fallout 3
