How co-op works
Up to six networked astronauts share a timed scenario after a meteor disables lunar life support. They inspect damage, transport replacement parts, operate rovers and repair robots, and allocate tools to restore oxygen production; completion time is scored, rewarding planned routes and parallel repairs.
About this game
Moonbase Alpha is a free cooperative simulation developed with NASA that drops you and your crew onto a damaged lunar outpost. A meteor strike has crippled life-support systems, and your team has a narrow window to restore oxygen generation before the base becomes uninhabitable. Every second counts, and every repair decision matters.

Players coordinate to assess damage, prioritize repairs, and operate equipment like robotic repair units and rovers across the lunar surface. The challenge lies in managing limited time and resources while communicating constantly with teammates. Success depends on clear callouts, role delegation, and quick thinking under pressure.
Moonbase Alpha supports online co-op for multiple players working together in real time. The scenario-driven structure and communication-heavy gameplay make it a surprisingly tense teamwork challenge, especially when repairs go sideways and the clock keeps ticking. It's a unique glimpse into the kind of coordination real lunar operations would demand.
