Returner 77

Returner 77 is a mystery sci-fi puzzler. You wake up inside an alien spaceship with no memory of what happened or how you got there. With help from Colonel Ling, you find that you are one of only two survivors from 77 people who were sent into space to be spared from a devastating war on planet Earth. You were given one mission - to return when the planet is livable again and rebuild the human race.
