Valve won’t be selling its Steam Controller anymore. That’s right, the gamepad for the PC gaming elite is reportedly going the way of the dodo — and the company is selling the last ones at a whopping 90 percent off.

Valve confirmed to The Verge that this would be the last batch of Steam Controllers. Originally released in November 2015, the controller was designed to work with Steam Machines, or anything that could run SteamOS. In addition to its big, obvious trackpads, it boasted back paddles and a built-in gyroscope. Last year Valve also activated the controller‘s Bluetooth, allowing it to connect to mobile devices running the Steam Link app.
