Microsoft unveiled the Proteus Controller on Wednesday. It is a modular video game controller kit that costs $299 and allows Xbox players with disabilities to personalize their controllers.

The wireless controller is a set of small cubes with replaceable faceplates that incorporate analog sticks, a directional pad, and controller buttons. It was developed by the peripheral business ByoWave as part of the Designed for Xbox initiative.

The components that simply snap together allow players to construct over 100 different layouts and lighting variations. This allows players with disabilities and others who play with one hand to customize how they use the controller to suit their needs. For a more personalized experience, you can also remap the buttons-but only with the help of the companion app.

The Xbox One, Windows 10 and 11, and Xbox Series X / S will all be compatible with the Proteus Controller at launch. Though it’s open to collaborating with these platforms, ByoWave says it won’t support the PlayStation 5 or Nintendo Switch.

Though it is currently discounted to $255 on ByoWave’s website, preorders for the controller are accepted, with shipping expected in the fall. The package will come with a Bluetooth dongle and a USB-C charging cord in addition to additional components like left and right grips for constructing an ordinary controller and two sizable one-button accessories.

Microsoft is updating its 2018 Xbox Adaptive Controller, which sold for $99.99 and was designed to assist gamers in creating adaptable gaming setups, in addition to releasing a new controller.

Each USB connection on the controller will eventually be able to accommodate up to 12 buttons, an additional stick, and a hat switch, expanding its compatibility. The firmware update will be made available to the general public in the coming months, but Xbox Insiders will receive it over the span of the next few weeks.
