A second OG Steam Controller prototype has been found at Goodwill
A second prototype of Valve's original Steam Controller has been discovered at a Goodwill store in Seattle, seven years after a similar find. The 'Chell' prototype, believed to be from 2013-2014, features a different button layout and lacks thumbsticks compared to the final retail version. The controller was found by the father of a 14-year-old Valve fan and reportedly functions as a generic controller.
