Midway Games was an American video game developer and publisher. Its titles included Mortal Kombat, Ms. Pac-Man, Spy Hunter, Tron, Rampage, the Cruis'n series, NFL Blitz, and NBA Jam. Midway also acquired the rights to video games that were originally developed by Williams Electronics and Atari Games, such as Defender, Joust, Robotron 2084, Gauntlet, and the Rush series.
The Bally/Midway division of Bally was purchased and reincorporated in 1988 by the arcade and pinball game company Williams Electronics Games through its holding company WMS Industries Inc. Midway moved its headquarters from Franklin Park, Illinois to Williams's then-headquarters in Chicago, and WMS reincorporated Midway as a Delaware corporation. Although WMS retained many of Midway's R&D employees, only two game designers were retained: Rampage designers Brian Colin and Jeff Nauman. WMS obtained the right from Bally to use the "Bally" brand for its pinball games since Bally had completely left the arcade/pinball industry to concentrate on casinos and slot machines.
