Apple's iOS devices have sparked a mobile gaming revolution, but let's face it: Real games need real, tactile buttons, and a new Kickstarter campaign aims to add them to four sizes of devices.

The brainchild of Milkshake Labs, the Coco Controller is a planned smartphone case to convert your mobile device into a real handheld game controller, complete with the hardware buttons gamers crave.Unlike other gaming cases already on the market, the Coco isn't limited strictly to Apple's iOS devices - in fact, there are four sizes planned for the Coco, with support for the Samsung Galaxy S III, the iPhone 4/4S, the fourth-generation iPod touch and the forthcoming sixth-generation iPhone.Yes, you read that right - Milkshake is allowing Kickstarter pledges to choose which case they want in November, by which time Apple will have certainly released their latest iPhone and the Coco will be ready for it!Coco includes one multi-axis directional pad, one analog stick, four action buttons and two triggers, and best of all it requires no battery and no Bluetooth connection. An audio out jack at the bottom of the case allows users to plug in headphones or speakers, which is also the same method the case uses to draw power and device communication from. Kickstarter backers can also vote on which colors the Coco will be available before launch.The creators of the Coco are aiming to raise $175,000 by September 12, and currently have the support of 31 mobile games, but are in "serious talks with several of the largest game studios" and plan to expand support for other titles by the time the case ships.
