To succeed at IMPOSSIBLE MISSION II and to prevent the world from being destroyed, you as the Agency’s Field Agent must reach several objectives. First, you must assemble the three-digit security combination for each tower. At the same time avoid and fend off Elvin’s robots, using his own security system to help you.

Second, you must locate and open Elvin’s safes, and recover the musical sequences locked inside. There are six unique pieces of music and two duplicate pieces.

Third, you must tie together these musical sequences into a full melody that will open the express elevator doors to Elvin’s central tower control room.

Finally, you must find the correct computer terminal in Elvin’s control room that will disarm the missile launch codes before they destroy you and the world.

You score points by entering towers, exploring rooms, finding passcode numbers, and reaching the central control room. The sooner you reach the control room, the more points you earn.
