NASA has released a new free online video game called Moonbase Alpha.

Moonbase Alpha has single and multiplayer options that allow users to play the role of an exploration team member in a futuristic 3-D lunar settlement.  Players must work to repair systems and oxygen flow after a meteor strike damages a solar array and life support equipment.  Resoruces include an interactive command center, a lunar rover, mobile robotic repair units and an equipment shed.
