The All Terrain Construction Transport (AT-CT) represented a unique construction-focused iteration of the All Terrain Scout Transport, classified as a walker. Production runs were constrained, and its original weapons were swapped out in favor of a tractor beam projector. The AT-CT's purpose was the movement of substantial resources during the building of Imperial structures.
The initial appearance of the All Terrain Construction Transport occurred in Star Wars: The Force Unleashed, a Star Wars Legends game developed by LucasArts and launched on September 16, 2008. The AT-CT received its first acknowledgement within the current Star Wars canon through Walkers and Ground Vehicles of the Empire and First Order, a publication from the Star Wars Encyclopedia series of canonical reference books, which was released on May 11, 2021.
