The guns were going to be bigger, but it kept falling over.
About this creation
I ordered 30 of those 1x2x5 bricks from Lego Pick-a-Brick and stacked them all into a pillar one day.
While I was taking apart the pillar, I thought, "Hey, these could make one wicked coilgun!" And the Judgement was born.
This walker has two big coilguns, one HUGE coilgun, two armor piercing cannons on the side and one machine gun mounted on the bottom. (No jokes.)
I actually cheated on this one, the legs don't really move. I was working on this for so long that I thought, "Aah, the shape looks good, so I'll just leave it that way."
Design flaw: The cockpit doesn't open unless the Big gun is tilted upwards.
