In recent weeks we have seen quite a few worthy LEGO mechs, almost as if creators around the world have received special orders (or inspiration) to focus their creativity towards building a mecha horde to fight a common foe. This armed and armored mech by Lu Sim is one of my favorites. Built using mostly light gray, it looks grounded in modern technology, particularly the shield, with its small window looking right out of Call of Duty.
Another thoughtful design is the missile racks on each shoulder, complete with access panels that close, to conceal this extra armament. From the back, we see an ammo feed for the Gatling gun, and a number of thruster jets to help this bad boy gain the higher ground.
