Revised Metal Gear D

A new model of nuclear-armed bipedal walking tank, the successor to the Metal Gear TX-55 concept. It was developed in 1999 by Dr. Drago Pettrovich Madnar, a scientist held captive by Zanzibarland.

In addition to nukes, this Metal Gear's enhanced arsenal includes a machine gun for close-range combat as well as missile launchers. The light armor plating on the leg mechanism it used to walk proved to be its weak point.
