Hori originally released its Wireless Horipad for Steam in October, but only in Japan. The controller features dedicated buttons that you can use to open menus in Steam, whether you're playing in Big Picture mode or on the company's handheld. Just like on the Steam Deck, the gamepad comes with touch sensors on its joysticks for motion controls and assignable back buttons.
The controller can connect to your computer or Steam Deck with Bluetooth or the included USB-A Bluetooth receiver. Hori says the wireless gamepad will last up to 12 hours on a full charge, but you can plug in its USB cable in case it runs out of power mid-game. Additionally, you can remap buttons and adjust joystick sensitivity, gyro controls, and gamepad turbo settings from the controller menu in Steam.
However, Hori's controller lacks some features you might expect to see on a Steam-specific controller, including vibration packs, a headphone jack, and a trackpad. Still, it seems like a decent option if you want a controller that's like an extension of your Steam Deck. It's a shame Valve hasn't revived the ultra-customizable Steam controller it discontinued in 2019.
