Cyclops

The Cyclops from Halo is the smallest of the UNSC walkers. Only seen the Halo Wars games, this exoskeleton was in fact, originally designed for logistical utility and not combat. By attaching an auto-cannon or another weapon to the forearm, this extra bit of walking armor provided a much-needed boost to infantry forces on the front lines.

This model has an internal cockpit that seats one minifigure. The mech can articulate all limbs.
