Every day is the same for Greyson Cross. Wake up, work out, eat. Except on Centurion things are different, the lack of oxygen might have something to do with that. After being stranded for 6 months Greyson must overcome his fear of the 'Uncharted area' and continue his mission he set out to do: see if Centurion is able to be inhabited by human beings. Though each day is harder for him psychologically, he must succeed, the entire fate of Earth is depending on it.
