You need a copy of Star Wars Legion core set to play this expansion.
The power of the Empire is visible on any subjugated world—few images are more representative of Imperial power than the shining white armour of a Stormtrooper or the rumble of a walker stomping through city streets or across the battlefield. Soon, you’ll be able to supplement your Stormtroopers with another symbol of Imperial oppression: the All Terrain Scout Transport!
An AT-ST is an awe-inspiring sight to the average foot soldier. It towers above the battlefield, stalking inimically forward on mechanised legs and raining a hail of fire and death from its laser cannons and powerful weapons systems. With the AT-ST Unit Expansion for Star Wars: Legion, you’ll find a single finely sculpted, massive AT-ST miniature, which can be assembled to loom over the battlefield and provide a rallying point for your entire army. Alongside this beautiful miniature, you’ll find an assortment of all the unit cards and upgrade cards that you’ll need to fully integrate the AT-ST into the Empire’s war machine—and your armies.
