The Ten Commandments of Moses.png

The Monoeye UFO is the boss of the second mission of of Metal Slug 3.

Series Information

This strange artifact of extraterresial origin was an ancient UFO created to serve as a beacon for the Martians. It is guarded by Monoeyes, who will come out to defend it from hostiles.

It is filled with strange energy that can transform humans into mindless zombies, who can spread the disease to others with fluids.

Details

Before fighting this boss, the player must first defeat the Monoeyes that protect it. After that, the spaceship will show itself. Its only attack is to illuminate its core, summoning monoliths with alien runes inscribed on them to fall from the sky above the player.

Before landing, a targeting laser will be zeroed on the player, indicating a planned landing spot, giving the player a moment's notice to get out of its way. After impact, the Monoliths will slowly sink into the ground. Shooting them will make them sink faster.

However, as the ship receives more damage, the monoliths will begin to drop faster until it becomes very difficult to dodge.

Variants

Tencommandments.gif Monoeye UFO: The original ancient spaceship.
Monoeye Gate: A variant encountered in Metal Slug Attack, summoning a group of Monoeyes to defend it from enemies. These Monoeyes are invincible, but tied to the Monoeye Gate's durability. Upon being summoned to defend the gate, they then track the nearest enemy and fire shots in unison. The gate itself is also capable of dropping monoliths to impede enemy movement. It can come back again for a second fight with increased durability, although it has to resummon the Monoeyes again.
Golden Monoeye UFO: A variant encountered in Metal Slug Attack, summoning a group a large area of monoliths to impede enemy movement, and doesn't summon Monoeyes, only monoliths. It is painted gold.

In Other Games

Trivia

  • The Monoliths may be a reference to the movie 2001: A Space Odyssey with notable allusions to the Ten Commandments of Biblical legend. A few obscure fringe theories even exist in real life connecting the Biblical Ten Commandments to extraterrestrial activity.
  • It is possible that whatever process the Monoeye UFO uses to make zombies has been replicated by the Amadeus Syndicate to create the zombies in Metal Slug 4, as seen with the Big John.
  • As seen in the concept art above, the Monoeye UFO has tentacle-like roots below its base buried underground.
  • The boss arena has a few blind spots where the Monoliths cannot crush the player. A speedrun tactic is to place a zombified player on one of the leftmost spots and spam the Vomit Laser attack.
