“The game is set in the distant future, where space transportation is common. Space trains carry passengers and goods all across space. A particular space train, however, had some very special cargo. Through a series of unfortunate events, this space train gets shot out of orbit and crash lands on a mysterious planet.. with one survivor.” – Official RoR Website
