The UFOs are remote-controlled flying saucers used by the martians in Metal Slug.


The remotely controlled spacecrafts are a faster variant of the Mini-UFO, the Martian spacecraft. They attack by firing a laser beam from their bottom, which takes some time to charge but cross the screen at an impressive speed. Unlike the Mini-UFO, they aren't able to warp.


  • They are based on the Nazi UFOs.
  • In Mission 3 of Metal Slug, when Allen is defeated, sometimes an UFO can be seen. It also can be seen in the game's Final Mission, after Morden explodes the bridge.
