Space Invaders
The alien depicted on the backglass was deemed an unlicensed use of the one used in the 1979 Hollywood movie Alien. Some playfield art elements and game sounds were borrowed from the 1978 'Space Invaders' video game which was still popular at the time that this pinball machine came out. Designer Jim Patla told us that his original drawing shows that all four flippers were to be the longer type. However, the upper two flippers were changed to the shorter type because longer flippers interfered with the lower flipper backhand shots. Three dimples on the playfield, representing flipper adjustment positions, can be seen at a distance from each end of the shorter flippers at a point where longer flippers would have met them.

Clone Chamber (captive ball) is dangerous, but 10K+10K to 50K is huge on this game, especially when collected via center top lane repeatedly
Hitting the ball through the center hoop gives 5000 points and adds +1 to the score multiplier up to 5X on the fourth time.
Red Invacder bonus (20-60K) *IS* multiplied by bonus multiplier. Max bonus is therefore 495K.
