Four Horsemen

The Four Horsemen (フォー・ホースメン) were an assassination squad employed by Zanzibar Land that specialized in close-quarters battles.

Early career
The Four Horsemen were comprised of former elite members of SAS, GSG 9 and UDT. They utilized their combined skills within confined spaces to their advantage. They took their missions directly from Zanzibar Land's president, Big Boss, where the target was of high priority.

The Four Horsemen fought against Solid Snake during Operation Intrude F014 in the central elevator of the Tower Building, under direct orders from Gray Fox and Big Boss. Despite the fact that they outnumbered Snake, he was able to defeat them all by taking them on one at a time.

Trivia
The Four Horsemen are named after the biblical figures from the Book of Revelation known as the "Four Horsemen of the Apocalypse."

Behind the scenes
In the original MSX2 version of Metal Gear 2: Solid Snake, the Four Horsemen were named Ultra Box. They were named after the British pop band Ultravox. Their name was changed to the Four Horsemen in the re-releases of Metal Gear 2.

There is a mandatory battle in Metal Gear Solid which resembles the boss fight against the Four Horsemen, in which Snake must fight off four stealth-equipped Genome Soldiers in the elevator of Communication Tower B.
