Why it matters: For gamers with accessibility needs, Microsoft just leveled up the controller game in a major way. The tech giant unveiled the Proteus Controller on Global Accessibility Awareness Day – a modular gaming setup that lets players essentially build their own customized controller.

This isn't Microsoft's first rodeo with accessible controllers. Its Xbox Adaptive Controller from 2018 was a game-changer, allowing those with limited mobility to craft a control setup tailored to their needs. But the Proteus takes it to a whole new level of flexibility and customization.

The core concept is a series of vaguely cube-shaped modules that can snap together like LEGO bricks. There are handheld grips, hall effect analog sticks with adjustable resistance, buttons, triggers, and plenty more components.

Two powered "Cubes" form the base, each with their own rechargeable battery and Bluetooth connection to sync up to your console or PC. You can have upwards of 30 modules snapped into a single mega-controller setup if you want. And it's not just Xbox – the Proteus will work with Windows 10 and 11 PCs right out of the gate.

From there, the configurability is basically limitless – over 100 million potential combinations using the components in a single kit are estimated. You can even combine multiple kits if you need extra modules or want to build separate controllers for different games.

It's being developed in partnership with accessory pros ByoWave as part of Microsoft's "Designed for Xbox" program. The company envisions the Proteus as ideal for one-handed gamers, those with chronic pain or mobility issues, or just anyone who finds traditional controllers uncomfortable or ill-fitting.

The Proteus kit – including a wireless USB dongle, charging cable, grips, and some starter modules – is available for pre-order now at $255, a discounted price ahead of its expected fall release.

Microsoft's accessibility efforts don't stop there. Its existing Xbox Adaptive Controller is getting a major upgrade too, allowing a whopping 12 buttons, a second joystick, and other add-ons per USB port once a firmware update rolls out.

Looking ahead, some of gaming's biggest franchises are baking in accessibility from the ground up. Diablo IV is releasing a video detailing its expansive accessibility features on May 16. And Candy Crush Soda Saga is adding an accessibility menu for adjusting audio, controls, and more.

Lastly, a new Xbox interface update will let you easily filter and browse games in your library based on specific accessibility credentials like narrated menus or input methods.
