How to Play Impossible Mission
Quick start
Press either button to begin. Enter a room from the elevator shaft, watch the robot’s route and hold up in front of furniture to search it. Stop in a corridor and press a button to open the pocket computer and examine collected pieces.
Controls
Left/right: walk and enter or leave elevators. Up/down: operate elevators and lifts. Up at furniture: search; at a terminal: use it. Either 1 or 2 jumps while moving; standing in a corridor opens the pocket computer. In computer screens, move the pointer with the pad and press either button to select.
Impossible Mission — About this game
Elvin’s underground complex hides the fragments of a password needed to reach his control room. Search furniture while avoiding robots, use lifts to explore the rooms and assemble the pieces with your pocket computer. Terminals offer ways to deactivate robots temporarily or reset lifts, making a dangerous room easier to search. The layout and puzzles change between games, so observation and careful movement matter more than memorizing one route.
