Impossible Mission — About this game
Search furniture while avoiding robots, use lifts to explore the rooms and assemble the pieces with your pocket computer. Plan the order of your search rather than moving from object to object at random. Remember useful routes and compare each new clue with what you have already found before choosing the next step.
