The eighth zone of Sonic the Hedgehog 2 (1992), Metropolis is the only one in the game with three acts, hence its reputation as an endless level. This city-factory of green metal, copper piping and molten metal houses the manufacture of the Badniks. The signature gimmick lies in the giant screws and nuts that Sonic turns to get across the vertical shafts, among gears, conveyor belts and presses. The starfish badnik Asteron, hidden in the walls, stays out of reach. The boss only arrives in Act 3: Eggman and his seven silver capsules, eight hits. The third act reuses an abandoned zone.

A sprawling factory-city, giant screws to climb, and a record length that has tested the patience of generations of players: Metropolis Zone is the most dreaded level in Sonic the Hedgehog 2. A tour of Eggman's industrial heartland.

It's not the final zone: Sky Chase, Wing Fortress, and the Death Egg still follow.

Metropolis Zone in Sonic the Hedgehog 2 — Green piping, red bricks and open-air machinery: Metropolis is the densest industrial zone in the game.

The second act of Metropolis Zone — The only zone in Sonic 2 with three acts, it stretches its setting well beyond the usual format.

Giant screws and traps

The signature gimmick is the giant screws and nuts that Sonic spins around to climb up or descend vertical shafts. Added to this are rotating gears, conveyor belts, and presses which, combined, can quickly trap the player. Note: the starfish Badnik Asteron, hidden in the walls, is practically impossible to destroy.

The giant screws of Metropolis Zone — The moving screws work as lifts and as traps: badly handled, they take the player backwards.

The Act 3 boss

You must reach the end of Act 3 to face the boss (Acts 1 and 2 don't have one). It's Eggman himself, in his Egg Mobile surrounded by a ring of seven silver capsules that turn into bouncing decoys. Eight hits to finish him.

An act born from a cut zone

A delicious development anecdote: Metropolis's third act recycles content from an abandoned zone, with an unseemly internal name ("Genocide City"), which the team had chosen thinking it "sounded dangerous" in English—a language they poorly mastered. This content was eventually merged into Metropolis.
