Warner Bros. Interactive Entertainment has announced that its popular Midway Arcade iOS game collection is compatible with the iCade, a retro arcade cabinet designed for the iPad. It’s a free update for users of the app, which is available for 99 cents from the App Store.

Midway Arcade brings back classic coin-op arcade hits of the 1980s including Spy Hunter, Rampage and Defender – with some unlockable as in-app purchases, including Gauntlet and Gauntlet II.

The iCade is a miniature arcade cabinet sold by ThinkGeek. It holds the iPad in a portrait orientation and incorporates a joystick and buttons that communicate wirelessly with the iPad. It costs $99.99.
