Valve reveals its very own controller -- with two circular trackpads -- joining the company's new operating system and custom hardware prototypes announced earlier this week.
Company tells CNET that a right thumbstick add-on will be released, though details about the attachment itself are currently undisclosed.
The addition is reportedly shown off in the latest issue of Japanese gaming magazine Famitsu.
The game company might also try to boost its ailing portable business by offering a new device next year.
Users can pop their iOS 7-based device into the controller and then lock it into place, creating a more traditional controller.
The device adds a right thumbstick to the 3DS portable in order to extend what developers can do with their games.
The new game device will come with a 4.88-inch display on top and a 4.18-inch screen on the bottom. Wait, what? It's bigger, but there's just one thumbstick?
Rumors are pouring in that the Nintendo 3DS is set for a serious redesign.
Child of Light is a brave move from a mainstream developer, and one that hopefully heralds a new way forward.
Pricing not available
Nintendo's suddenly strong sales last month are the result of a price cut that dropped the handheld game player from $249 to $169.
