release a free video game to drum up some attention for its cause, why not NASA? That seems to be the argument behind Moonbase Alpha, a free game developed along with NASA that's now available on Steam. With up to six players at a time, the game allows you to experience the surface of the moon while trying to "repair and replace equipment in order to restore the oxygen production to the settlement," after a meteorite causes system failure.
The official page calls it a "First Person Explorer" title, and shows players fixing equipment connections and even building and controlling a Wall-E style repair robot. The graphics even look good, too -- exactly like that television studio NASA filmed those "moon landings" in. Nice try, NASA, but everybody knows it's nothing but green cheese up there.
