Space Quest 4 was released on floppy disks on March 4th, 1991, and in December 1992 on CD-ROM with full speech support, with Laugh-In announcer Gary Owens as the voice of the narrator. Using the SCI engine, it featured 256 colors, hand painted graphics, and a full, mouse-driven interface. It was one of the first-ever games to use motion capture animation. The game cost over $1,000,000 US to produce, but sold more than its three predecessors combined.

Synopsis Edit

In this installment, Roger embarks on a wacky time-travel adventure to Space Quest games both past and future. A reborn Sludge Vohaul from Space Quest XII chases Roger through time in an attempt to capture and kill him. Besides this postapocalyptic era, Roger also visits Space Quest X (Latex Babes of Estros) and Space Quest I, where the graphics and music become retro and Roger is threatened by a group of monochrome bikers who consider Roger's 256 colors pretentious.

  • While managing Vohaul's server, there are various icons on his desktop. One of them is a King's Quest game, which when deleted will remove a lot of data, referencing the increasing size of King's Quest games. One of them is Space Quest IV itself, which when deleted will close the game.
  • In the CD version, the game will be remarkably harder due to faster processing. Various places where you need to quickly avoid the Sequel Police will be made almost impossible because they appear almost immediately. This was fixed in the 2016 compilation (which slows it down with dosbox timings).
  • If you skip the arcade sequence, you will lose points.
