Google Stadia Controller

Stadia is a cloud gaming service developed and operated by Google. It is capable of streaming video games to players at up to 4K resolution at 60 frames per second with support for high-dynamic-range (HDR) via the company’s numerous data centers.
Google developed its own controller for Stadia. It has two thumbsticks, a directional pad, four main face buttons, two sets of shoulder buttons, and five additional controller face buttons.
