Early start on my AT-PT from star wars, I plan on introducing this as both a scenery asset and then later, as a driveable vehicle. Have to leave for the weekend so I thought I'd leave it here for criticism until I get back.
The AT-PT was an Anti-Infantry walker developed by the Old Republic, and constructed units were used well into the reign of the Galactic Empire. With a heavy blaster turret and concussion grenade launcher, it was extremely well-suited to anti-infantry combat, though it lacked the armor for anti-vehicle operations. Using legs instead of wheels or tracks allowed it to cross more dangerous terrain, though they also presented unique challenges and weak points for focused enemy fire.
