Space Quest 6: Roger Wilco in the Spinal Frontier is a comedic point-and-click adventure game developed and published by Sierra On-Line in 1995.

It is the sixth and final game in the Space Quest series and, like the previous titles, features numerous parodies of science fiction media.

Later, Commander Kielbasa of the DeepShip awards the crew shore leave on the planet Polysorbate LX while an elderly woman named Sharpei plots Roger's demise.

The game's subtitle comes from the final portion, in which Roger has to undergo miniaturization and enter the body of a shipmate and romantic interest, a spoof of the 1987 movie Innerspace.

(This segment also provided the game's original subtitle, Where in Corpsman Santiago is Roger Wilco?, which was not used due to legal threats from the makers of the Carmen Sandiego products.)

Josh Mandel designed the majority of Space Quest 6 (with Scott Murphy on board in a "creative consultant" capacity) but had to leave the project shortly before completion due to internal strife with Sierra.

So not only was I very upset not to see it in the game, but the fact that they had to put the Datacorder hints in the manual, leading player to think it was meant to be copy protection, disturbed me greatly.

"[4] PC Gamer US's Gary Meredith wrote that it is "not the best of the Space Quest series", as it takes "a couple of steps backwards as far as the graphics and voice-overs are concerned".
