Alone.

Leo was alone. He had gone on a space expedition in the year 2154, but he would not return when scheduled. It was a simple trip to the moon, bring back the resources the mines had collected. His luck took a turn when his crew was killed in an accident with the mines. When he manages to return to Earth he finds a lonely, deserted place. He soon finds that Earth has been left behind, a new planet that can support life has been found. He has to survive with only his wits, his personal computer program E.V.E. and the materials he finds. Will he ever find another human?
