NASA created the game as a part of its Learning Technologies project to “engage and educate students about agency technologies, job opportunities and the future of space exploration.”
In Moonbase Alpha, you assume the exciting role of an astronaut working to further human expansion and research. Returning from a research expedition, you witness a meteorite impact that cripples the life support capability of the settlement. With precious minutes ticking away, you and your team must repair and replace equipment in order to restore the oxygen production to the settlement.
What’s really interesting is that the game not only has a single player mode, but supports co-op/multiplayer play as well.
The game is free to download via Steam; details at http://store.steampowered.com/app/39000/
