Overview
Space janitor Roger Wilco is enjoying a rare moment of peace at his favorite interstellar dive bar when he is suddenly ambushed by the heavily armed Sequel Police. They have been sent from the future by Sludge Vohaul, Roger's mortal enemy, who has somehow survived his previous defeats and intends to erase Roger from the timeline entirely. Rescued at the last second by a mysterious figure who tears a hole in the fabric of time, Roger is dumped into the bleak, post-apocalyptic future of Space Quest XII: Vohaul's Revenge II.
To survive and stop Vohaul's chronological tampering, Roger must travel both forward and backward through the Space Quest timeline. The game features a brilliant meta-narrative where Roger visits the world of Space Quest X: Latex Babes of Estros, and even travels back to the original Space Quest I. In one of the greatest visual gags in adventure gaming history, the stunning 256-color VGA version of Roger is forced to walk through the blocky, 16-color EGA graphics of his own past while evading monochrome biker gangs.

Behind The Scenes
The Death of the Text Parser
Space Quest IV represented a massive paradigm shift for Sierra On-Line. It was the first game in the series to completely abandon the classic text parser—where players had to furiously type commands like "look at rock" or "use keycard on door" before an enemy caught them. Instead, it introduced an entirely mouse-driven, icon-based point-and-click interface. This made the game far more accessible, allowing players to focus on the puzzles and the comedy rather than fighting the game's vocabulary.
The High Cost of VGA and CD-ROM Talkies
The visual upgrade was staggering. Sierra employed professional traditional artists to paint the backgrounds on canvas, which were then digitally scanned into the game, ballooning the production budget to over $1 million—a monumental sum for 1991. Furthermore, when the game was re-released on CD-ROM a year later, it became one of the industry's first full "talkies." Sierra hired Laugh-In and Space Ghost star Gary Owens to provide the narrator's voice, perfectly capturing the booming, melodramatic tone of mid-century sci-fi serials.
