Play Space Quest IV: Roger Wilco and the Time Rippers Online – MS-DOS Game

Game Overview

In contrast to the first three games, Space Quest IV uses a point-and-click interface, featuring icons for different actions. The icons are an eye, a talking head, a walking person, a hand, a mouth, and a nose, representing look, talk, walk to, use, taste, and smell, respectively. The last two almost never do anything other than provoke a humorous response from the game.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
