Moonbase Alpha

A meteorite has crippled the oxygen supply of a real NASA moonbase, and you have minutes to fix it. Repair systems with up to six friends, drive rovers, pilot repair robots, and race the clock. A serious lunar survival sim that accidentally became a comedy legend.

Is Moonbase Alpha worth it?

Moonbase Alpha is worth it if…

  • you like co-op games where a lobby of friends shares one clear objective
  • you enjoy puzzles about priorities, tools and doing things in the right order
  • you want a space game about engineering and teamwork, not combat
  • you like games with a sense of humour, intentional or otherwise
  • you prefer short, focused sessions over long campaigns

Fixing a dying moonbase against the clock

You come back from a research expedition to find a meteorite has smashed into the settlement and knocked out life support. Oxygen production is down, and the colony has a limited window before it fails. Your job is to repair and replace the damaged equipment before time runs out. There is more than one way to get the base breathing again, so part of the game is deciding which route your team takes: what to fix first, which tools to carry, and who does what. Every session is scored on the time you spend, so a sloppy run teaches you something for the next one. Work fast, work smart, and the base survives.

Rovers, robots and NASA-grade hardware

You are not fixing a moonbase on foot alone. A fully functional rover built on real lunar physics carries players and supplies across the colony, so nobody has to haul a heavy part across the regolith by hand. You can also build and pilot your own repair robot, sending it in to fix crucial systems while you handle something else. Managing these resources well is the difference between a comfortable save and a frantic one: the tools are there, the question is who uses them and when. It is maintenance work turned into a team puzzle, where priorities matter more than reflexes.

Six astronauts, one voice channel

This is a game built for a lobby. Up to six players can join over LAN or internet and coordinate by voice, splitting the rescue: some repair systems, someone drives the rover, someone runs the robot. Joining is straightforward, the objective is shared, and the rounds are short, which makes it an easy thing to play with friends on a weeknight. And because everyone is on voice chat while a colony quietly runs out of air, the game has a second life nobody at NASA planned: the built-in text-to-speech voice became an internet legend in its own right, and shouting nonsense at each other mid-repair is now part of the experience.
