The Ultimate Collector Series AT-ST Walker faithfully recreates the Imperial all-terrain vehicle from the Star Wars saga with authentic LEGO brick construction. This 1,513-piece build captures the distinctive walking machine's instantly recognisable features, including its characteristic articulated legs and detailed two-person cockpit accessible through an opening top hatch.

The model offers several interactive display features for customisation. The walker's head section rotates fully, whilst the viewport shutters can be opened and closed to match different scenes from the films. The laser cannons are also adjustable, allowing builders to position them for dynamic display arrangements.

Construction and Display

The set includes a detailed information plaque and an exclusive AT-ST Driver minifigure featuring the Imperial crest on the arms and an accompanying blaster pistol. These elements complete the display presentation typical of the Ultimate Collector Series line.

The finished model measures 37 cm high, 22 cm long and 22 cm wide, making it a substantial display piece that captures the imposing presence of the original vehicle. The complex construction process is supported through digital building instructions that provide 3D visualisation and progress tracking throughout the build.
