Cortex Labs

Build the rails. Harvest the planet. Fill the rocket.

Cortex Labs is a small sci-fi logistics strategy game for classic x86 PCs. Build rail networks, use cargo pods to collect alien resources, and refine green Neurofung to fill and launch the rocket. The game is written in assembly, runs as a DOS .COM program, and can boot directly from a floppy disk.

Core Features

  • 6 fixed seeded maps, plus a randomized map
  • Rail-building logistics across a large 128x128 alien world
  • Cargo pods that move resources through player-built rail networks
  • Stations, switches, collectors, extractors, silos, refineries, labs, radar, and pod factories
  • Three resource types to extract, transport, store, and spend
  • Refinery system: turn green Neurofung into rocket fill progress
  • Laboratory upgrades for faster pods, faster extractors, longer extractor range, and bigger silos
  • Resource storage limits expanded by building silos
  • Fog of war and radar visibility expansion
  • Mouse gameplay with keyboard shortcuts
  • Victory goal: fill the rocket and complete the mission

Story

Earth's last unaging generation is dying.

For three decades, Cortex Labs has chased Neurofung — a wild organism found only on Kepler-486i. A single gram can extend cognition and cellular life. A full rocket could change the fate of humanity.

You are Orbital Commander: the remote mind of an automated mining expedition.

Harvest. Refine. Launch.
