Two astronauts are exploring an unknown sector in space experience a systems malfunction in their exploration pod, making it explode. With broken comm lines, no way to contact the mothership, they both tether themselves together and use what thruster fuel they have left to get back to base. 

Your objective as the player is to control both the astronauts and guide them back to the mothership. The only way to tell if you're heading in the right direction is a distress signal, which tells you how far you are from your ship. Get back to it before your oxygen runs out. Beware of floating asteroids and space debris! We need them both back in one piece.
