Chip 'n Dale Rescue Rangers is a platformer video game developed and published by Capcom based on the Disney animated series of the same name. Originally released for the Nintendo Entertainment System in Japan and North America in 1990, it would later come to Europe the following year, as well as receive a port for the Nintendo PlayChoice-10 arcade system. The game would go on to sell approximately 1.2 million copies worldwide Chip 'n Dale Rescue Rangers is a platform game featuring single and 2-player cooperative modes, allowing players to choose which levels to access via a map of various locations throughout the city, in a similar format to other Capcom games such as Bionic Commando. Each individual stage is set up as a side-scrolling action game where Chip and Dale can walk, jump, duck, and pick up objects such as acorns, crates, barrels, and balls to throw at enemies and bosses. Each character can withstand only three direct hits before they lose a life, and there are no passwords. In two-player mode, Controller 1 is Chip, Controller 2 is Dale. The rest of the Rescue Rangers also appear to support Chip and Dale. Monterey Jack will occasionally appear to break down certain barricades, while Zipper grants temporary invincibility to the player when found. Gadget, though in Fat Cat's captivity, provides tips and advice for the chipmunks in each stage. The Rescue Rangers are going on a mission to retrieve a missing kitten for a girl named Mandy. As Gadget goes on ahead to scout the area and Monterey Jack is sent to investigate sightings of strange mechanical dogs with Zipper, Chip and Dale proceed through the streets and into a laboratory, where they are attacked by a crazed robot. After defeating the robot, Fat Cat appears and reveals that 'Mandy's kitten' was just a distraction so he could kidnap Gadget and force her to work for him. Fortunately, Gadget is able to contact Chip and Dale by building a wireless phone and sending a map to them via carrier pigeon, allowing them to navigate through the treacherous landscape and reach Fat Cat's casino where she is being held. After rescuing her, Gadget provides the chipmunks with a rocket that sends them towards Fat Cat's hideout so they can defeat him.
