About save the city

A tourist on vacation turns out to be the only person who can defend two cities. Save the City is a 3D action game that sends that unlikely hero through Seoul and Waikiki to stop rogue AI forces, corrupted E.R.A. heroes, and giant robots.

The creator describes it as a childhood game, so it reads as a personal project. It was made with Codex and Three.js as a single-player browser game, and it went into Vibe Jam 2026, where it came 378th of 945.

The setting is the draw: both battlegrounds are real-world locations, and the hero starts as an ordinary vacationer rather than a trained fighter. The enemy list pairs former heroes who have gone bad with oversized machines, which gives the story a comic-book feel.
