From the Metal Gear Wiki

Metal Gear Chaioth Ha Qadesh is a Metal Gear.

[edit] Overview

The name Chaioth Ha Qadesh is derived from the Keter, a high level in the Kabbalah, a mystical system often confused with Judaism. The name refers to a group of angels, called The Holy Living Creatures (Chayot Ha Qadesh - "חיות הקדש" in Hebrew).

Originally designed as a way to control Model 3 test subjects, Chaioth Ha Qadesh uses the EGO (Enhanced Governing Organization) Operating System to control various modified soldiers and guard robots. SaintLogic developed the Metal Gear for that purpose, but Dr. Thomas Koppelthorn stole Chaioth Ha Qadesh as a means to get revenge for his wife Lucinda and kill all involved in the Praulia Massacre.

Like other Metal Gears, Chaioth Ha Qadesh can fire a nuclear missile from any area of the world to its target. However, one difference is that it mainly uses Neutron Bombs as its main weapon, and also contains the data on all test subjects in the SaintLogic institute. It has a missile launcher on its back, and can fire bullets from the Vulcan Cannons on each of its arms. It also has a slot on the top for launching energy that can cause any equipped cards to be destroyed.

Metal Gear Chaioth Ha Qadesh uses nano chip expansions so the player can see what cards the Metal Gear has and will use. The cockpit, located in the upper zone of Metal Gear's head, can be ejected, which Lucy uses to kill Koppelthorn by launching him out of Chaioth Ha Qadesh and then destroying the cockpit (and what was inside it) with a missile. At the end of his mission, Solid Snake empties its equipped nuclear warhead, hides inside the casing, and launches himself into the ocean to escape US soldiers.
