This trooper is armed with 2 Z-8 chain guns. Droids won’t know what to do as they are blasted to bits. The Lego Prototype Anti-Droid Exosuit is an MOC created by tommilorenzo. It is amazingly compact and fits a single Lego Minifigure perfectly. The reactor core on the back of the exosuit is a great detail, as are the various vents and pipes (for cooling?). It all comes together pretty well!
