Space Quest 6: The Spinal Frontier, is a point and click adventure game released in 1995 by Sierra On-Line. The game was released for PC (DOS / Windows) and Macintosh.
The game begins when Roger Wilco faces a court martial for various humorous reasons (Roger has no words to defend himself). He is demoted back to the post of a second-class janitor on board the SCS DeepShip 86 (parody of Deep Space 9). Among the reasons why Roger was simply demoted and not expelled from StarCon is "the safe return of SCS Eureka". But these events are just the beginning of much bigger problems that Roger will have to deal with. Once again, the future of the galaxy depends on it!
