Space Quest VI: The Spinal Frontier

Roger Wilco, the brave interstellar janitor who has already saved the universe from many great dangers, is now in a very embarrassing position. His commanders show no respect for his courageous actions in the previous game. Instead, he is being accused of all kinds of violations against the galactic law, is deprived of all the honors he got in the previous game, and as a token of mercy, is allowed to return to his old job – cleaning closets… But those unfortunate events are just the beginning of much bigger troubles Roger will get into. Once again, the future of galaxy depends on him!
