Metropolis is a game inspired by Capcom's Trojan, offering a unique twist on beat 'em ups. Players must defeat enemies using only a sword and shield. Set in a post-nuclear disaster city governed by the law of the strongest, players control Geitor, tasked with restoring peace. By leading a revolt and eliminating five nuclear tanks held by the city's evildoers, Geitor aims to establish peace in Metropolis. Opposition comes from three factions: The Warriors of Death, The Dartfire mutants, and The Girlkiller gang.

The whole city is a real trap, full of dangers behind every corner and with a multitude of enemy warriors ready to end Geitor's aspirations. The best warriors of the forces of evil have set out to destroy themselves and end the Townsman rebellion in this way.
