This game is centered on multiball modes. After hitting the five yellow standup targets a set number of times, the player can hit the right inlane to light "Quick Freeze" on the left ramp, then shoot the ramp to light one of the four Freeze lamps in the center of the playfield. Once the required number of balls have been frozen, a shot to the left loop will start multiball, putting one additional ball into play for every freeze earned.
Fortress Multiball - A normal multiball mode in which the player must hit a set number of lit jackpot shots in sequence to enable the Super Jackpot.
Museum Multiball - Every shot is lit for a jackpot; once they are all hit, the Super Jackpot lights up.
Wasteland Multiball - Similar to Fortress, but more than one jackpot can be lit at a time.
Cryoprison Multiball - The Super Jackpot is immediately lit; all jackpot shots add to it.
The four modes are always played in this order. For all except Cryoprison, the player can increase the starting jackpot value by freezing additional balls before starting the mode. Completing all four multiball modes lights a "Demolition Jackpot" at the right ramp, which is calculated based on the number and value of the jackpots scored during every mode. This award goes out of play if the ball drains, or if another multiball is started. The Museum Multiball music is based upon Brahms' Second Symphony, 2nd Movement.
Cryo-Claw modes
The game's other main feature is the Cryo-Claw, which is located on the upper-left side of the playfield. Completing all three rollover lanes above the jet bumpers lights the left inlane, which in turn lights the right ramp for a shot to the Cryo-Claw. The ball is lifted off the field, picked up by a magnet on the end of a pivoting arm, and swung over five exit lanes arranged in an arc. Each lane corresponds to a different award; the player must press both gun triggers to drop the ball into the exit for the desired one. The awards are as follows:
Start AcMag - Hit the center to score extra points for a limited time.
Lock Freeze - Freezes enough balls to start the next multiball, or starts it immediately with one additional ball if the required number have already been frozen.
Prison Break - Lights "Car Chase" for bonus points; completing it awards a further bonus.
Super Jets - Bumpers award 1 million points per hit.
Capture Simon - Shoot three lit arrows to collect a bonus.
Completing all of the Cryo-Claw modes lights the Underground shot for the wizard mode, Demolition Time. In this mode, three balls are launched into play, and all of the major shots are initially worth 15 million points. Hitting the five standup targets increases the base value of all the major shots by 5 million points, and launches another ball into play, up to five balls.
