From the Metal Gear Wiki

"If it is completed, nuclear attack from anywhere will be possible. Metal Gear must be destroyed before it is completed"

— Gray Fox to Solid Snake, Metal Gear

Metal Gear TX-55, also referred to as TX-55 Metal Gear, was a bipedal tank designed at Outer Heaven by the Eastern scientist Dr. Drago Petrovich Madnar, based off the technology designed by Granin during the Cold War.

The maker of Metal Gear TX-55, Dr. Madnar, while he understood the power and inherent evil of his creation, the kidnapping of his daughter forced him to complete it.

Metal Gear TX-55 was a revolutionary weapon because of it's ability to launch a nuclear attack from any stable territory, without the need of a nuclear silo. Feared by the Western powers, its mere presence on Outer Heaven made the country virtually untouchable, except of course, by a covert mission.

Metal Gear TX-55's weakspot were its feet, which could only be destroyed by placing plastic explosives over them in a determined order. The TX-55 was armed with a 20mm vulcan gun, a laser cannon and multiple medium-range warheads. However, none of its arsenal was put to use, as the TX-55 was destroyed by Solid Snake before completion.

Metal Gear TX-55 was succeeded by Metal Gear D, and later, units such as Metal Gear REX and Metal Gear RAY.

[edit] Behind the Scenes
