The year 2476, Earth's space-federation has been building moon-bases across the galaxy. One of those moon-bases has been sending a distress signal. Space Grunts are a group of intergalactic "problem" solvers, sent to investigate..
You play one, out of a team, of Space Grunts, and your mission is simple: find your way into the moon-base, and figure out what has happened. You'll have to fight your way through aliens, robots, security drones and base-systems.
