Revision 2.0 31 October 2020 Credits Changes designed and implemented by Soren Worre. Based on the revision 1.2 software released in 1996 by Williams Electronics Games Inc. The author would like to thank the designers of this pinball machine. Summary The video modes in the game are toned down. For better flow of the game and because video mode was too easy to repeat playing. The hugh scoring potential of the Super skill shot now limited. The under exposed Time machine mode (in competition play) can now be played more than once per game. Two new feature adjustments. Improvements Better suitable for competition play. Much more enjoyable without the overly exposed video modes. The Time machine feature is more into play. Detailed changes description Reference to the 1.2 revision. New feature adjustment A.2 18 "Time machine per mode completion". Options: "Yes" and "No". - "Yes": Completing an Adventure mode will light Time machine. - "No": As rev. 1.2. Default: "Yes". New feature adjustment A.2 19 "Super skill shot". Options: "Standard", "Moderate" and "Disable". - "Standard": As rev. 1.2. Super skill shot offers up to 10 shots for at total of 13.75M points. - "Moderate": Super skill shot offers up to 3 shots for at total of 1.5M points. - "Disable": Super skill shot is never offered as one of the plunge awards. Default: "Standard". When Tournament play selected: Time machine modes will follow a sequence ordered by date. Player individual. - The mamushka - Move your car - Saucer attack - Knight mission The sequence will repeat. Qualify DOG video mode (Spot DOG) is removed from the plunge awards. Start DOG video mode (Run from Spike/Save the girl) is removed from the Magic bus awards. Big points replaces the DOG video mode in the Tournament play sequence. When a DOG video mode is played, no further DOG video modes can be qualified on the DOG ramp on the same ball-in-play. The DOG objective will remain non-timed. New DMD texts for when a DOG completion is awarding bonus-x increment or points only. Bonus-x does not carry cross balls. Adjustment A.1 21 "Language" is limited to "English". Adjustment A.1 28 "Min. vol override" defaults to â€œYesâ€. Note Assembling the Toaster gun will always qualify Save the girl. Time machine modes qualified cannot be stacked. The mode Air tactical combat will take precedence over the Crane, which will stay down during the mode running. This may be inconvenient and seem buggy, if Multiball is lit. Or multiball is started (via sneak-in). The DMD "Shoot the crane" is ambiguous. It can both mean shooting the wrecking ball into the cars. And the lane behind the wrecking ball. Shooting the wrecking ball into the cars during multiball will not award the jackpot. Contrary to what the DMD "says". However, Air tactical combat will award the player a score similar to a jackpot.
