The story of Metal Slug 3 begins several years after the defeat of General Morden. While order has supposedly returned to the world, the Metal Slug Wiki notes that the Peregrine Falcon Strike Force (Marco and Tarma) and the intelligence agency S.P.A.R.R.O.W.S. (Eri and Fio) discover that Morden’s forces have not disbanded but are instead hiding and building new strongholds. The Rising Threat
The team is dispatched to investigate a series of strange phenomena, including mutated wildlife (like giant crabs) and reports of livestock abductions. These bizarre events, described by TV Tropes, suggest that the Mars People—the alien race that previously allied with Morden—have returned to Earth with a more sinister agenda. The Great Betrayal
During the final mission, the heroes launch a full-scale assault on what they believe is Morden’s headquarters. After a fierce battle with Morden in his "Hi-Do" helicopter, a shocking twist occurs:
The Fake Morden: The Morden you just defeated is revealed to be a Mars Person in disguise.
The Abduction: The real General Morden is shown chained to an alien vessel, and the aliens promptly abduct the player character (Marco, Tarma, Eri, or Fio) into outer space. The Final Showdown
In an unprecedented move, the Regular Army and Morden’s Rebel Army form a temporary alliance to rescue their captured comrades. They launch an armada of rockets into space to infiltrate the alien mothership, the Rugname.
Inside the ship, the remaining heroes battle armies of clones created from the abducted character.
After freeing the original character and General Morden, the team escapes the collapsing mothership.
The final battle takes place during a free-fall back to Earth against the alien leader, Rootmars, a massive brain-like creature. The Ending
Once Rootmars is defeated and plunges into the ocean, the heroes land safely. As the Rebel Army retreats in captured UFOs, one of the protagonists throws their gun into the sea, signifying a hope for peace. However, a post-credits scene shows the gun hitting a "fishman" deep underwater, hinting that the world's bizarre troubles are far from over. To see the story and all its branching paths in action:
