Space Quest IV: Roger Wilco And The Time Rippers

In this installment, Roger embarks on a time-travel adventure through Space Quest games both past and future. An infomorph of reborn Sludge Vohaul from Space Quest XII: Vohaul's Revenge II chases Roger through time in an attempt to finally kill him. Roger also visits Space Quest X: Latex Babes of Estros (whose title is a parody of Infocom's game Leather Goddesses of Phobos) and Space Quest I; in the latter, the graphics and music revert to the style of the original game and Roger is threatened by a group of monochromatic bikers who consider Roger's 256 colors pretentious. None of the gameplay takes place in Space Quest IV. In fact, the "actual" Space Quest IV is only seen briefly in the introduction.
