Space Quest 6: Roger Wilco in the Spinal Frontier

Space Quest 6: Roger Wilco in the Spinal Frontier is a 3D animated adventure game published by Sierra On-Line in 1995. It is the sixth and final game in the Space Quest series, and like its predecessors is a sci-fi comedy featuring janitor turned hero Roger Wilco. Despite his success in saving the galaxy, again, in Space Quest V, Roger has been court martialed and is once again a janitor.

Space Quest 6 picks up where Space Quest V left off; although he had saved the galaxy from the mutant threat, Roger is court martialed and demoted to the rank of janitor second class about the ship SCS DeepShip 86. As the game begins, the ship's crew is given shore leave on the planet Polysorbate LX. Once on the planet surface, Roger's adventures begin: He'll need to survive a plot to kill him and eventually is miniaturized and sent into the body of his love interest, Stellar Santiago, in order to save her.

Space Quest 6 was developed using a later version of Sierra's SCI game engine. The graphics and animation style is more cartoonish than previous Space Quest games and incorporates a combination of 3D rendered and hand drawn style images. Technical improvements to the engine allow the game to have sharper graphics than its predecessors (it supports Super VGA graphics with a 640x480 256 color resolution) and include full voiceovers throughout with Gary Owens (from the t.v. show Laugh-In) once again providing the voice of the narrator. The interface for Space Quest 6 is different than the one used by other Sierra point-and-click games; instead of the usual series of icons accessed by a menu at the top of the screen, the game features various verbs listed at the bottom of the screen. Players can click on the verbs and objects in the screen to form sentences that command Roger to perform an action. The interface is very similar to the one used by Lucasfilm's SCUMM game engine (which was used by games such as The Secret of Monkey Island and Maniac Mansion).
