World Defender

Conversion kit for unspecified Bally machine(s) which included playfield, backglass and artwork panels for the cabinet. Reportedly, this 1985 kit works with Bally games that have either the AS-2518-17 MPU or the AS-2518-35 MPU. The flyer shows the pop bumper caps are yellow and have the name of the game on them. Pictured in this listing are two examples of this game, each having blue bumper cap tops with no name on them, similar to those found on Gottlieb's 1981 'Black Hole'. We don't know if this conversion kit offered only one style of bumper caps but it would seem likely a kit would only use the game-specific caps. Game play similar to Williams' 1984 'Laser Cue', according to Pinball, Lure of the Silver Ball, page 121. A comparison of the disassembled software for this game showed it was derived from the software from Bally's 1981 'Eight Ball Deluxe'. Prior to this game, this manufacturer was known as Bell Games.
