Destroying machine army cube

A white cube rose up out of the smoke, about fifteen feet across on each face, with six black spider legs and three green lights on the front 'face'.

The lights flared, and a laser beam drilled into the child-flesh of the Mother Giant, parting that wave.

I pulled away more of the grappling lines and rose up higher. Once I'd achieved enough height to not be constantly bound down, I shot the big cube, aiming at the glowing lenses until the power cell behind them detonated.
