Space Quest 6: Roger Wilco in the Spinal Frontier is the last entry into the Space Quest series and was developed and published by Sierra On-Line in 1995 for DOS and Windows. It made its way onto the Mac the following year.
This entry was the first exclusively on CD-ROM and featured a verb interface similar to the LucasArts SCUMM engine. Although SQVI leaves off with a cliffhanger ending, a seventh installment was not meant to be.
After saving the galaxy from disease in the previous chapter, Roger is of course court-martialed for his efforts. No good deed goes unpunished, as they say. Demoted all the way back to his original job as a janitor doesn’t stop him for having to save the galaxy all over again. In true Space Quest style, SQVI is steeped in humor and sci-fi parodies. Parodying everything from Blade Runner, Wing Commander, Star Trek, and more. Though reviews were mixed on this one, it being hilarious was one thing they could agree upon. There was a bit of strife during development of this title and some of the puzzles suffered for it. However, Space Quest 6 was not a bad way for a great series to end. SQ fans will definitely want to play this final chapter, newcomers should start at the beginning.
Beware, it's quite a big download!
