Wow, now this is more like it!
You arrive at an outpost on Mars to find an empty station with obvious damage... and set about investigating and repairing as much as possible... so very good gameplay. As you progress, you begin to suss out the reason for the disaster... and it's a doozy; thereafter, your mission is to cure the virus, try to find any survivors, and finally navigate to a new home world for a fresh start. Great story, lots of gameplay, and a hopeful ending - who could ask for more?
