Underground restoration

The surface is gone.

A solar storm has made the surface uninhabitable. As engineer Noor, you must rebuild the underground city's water, power and transit network before the Seed Vault opens.

Connect districts by building pipes, cables and rails between nodes on the map.

Developer Log: Cultivating Metro Bloom

Metro Bloom explores a post-apocalyptic setting where nature reclaims an abandoned subway system. It blends elements of city-building, gardening, and resource management into a unique, subterranean experience.

Simulating the Ecosystem

The core of Metro Bloom is its interconnected resource simulation. Water from surface leaks must be routed to filtration tanks, which then feed the hydroponic fungal farms. We wrote a custom cellular automata system to handle the flow of water and the gradual spreading of moss and roots across the subway tiles.

Atmosphere and Lighting

To sell the claustrophobic yet beautiful atmosphere of an underground greenhouse, we implemented a dynamic 2D lighting engine. Bioluminescent mushrooms and jury-rigged neon signs cast colored light across the tiles, creating a stark contrast with the deep shadows of the abandoned tunnels.
