Valve's Steam Controller Set for Monday Launch at $99 with Mechanism Accessories

Valve's new Steam Controller is scheduled to go on sale on Monday for $99, with accessories from Mechanism available on the same day. The Verge reported that Mechanism's new Basegrip provides the first way to attach a Steam Controller to a phone. Mechanism's lineup also includes mounts for hanging handhelds and gamepads on the Ikea Skadis pegboard.

The Steam Controller mount will launch alongside the controller itself, following Valve's decision to grant Mechanism early access to the design. When paired with Mechanism's phone mount, the Basegrip allows the Steam Controller to remote-control a PC via the Steam Link streaming app. However, Mechanism stated that the controller does not work across all of iOS or Android yet.

Testing showed that playing games with the Steam Controller using the Steam Link iOS app functioned successfully, according to Jay Peters. Mechanism is opening a waitlist for a Steam Controller dock that positions the controller at an angle. The Steam Controller includes a charging puck that attaches magnetically, though the puck and connected controller typically lay flat on the ground.

Mechanism stated that its dock is perfectly weighted for the controller. The dock is designed to display, charge, and connect the Steam Controller. It will launch in June 2026. Mechanism is offering free files for 3D printing versions of the Basegrip and a stripped-down dock.

Valve previously used dozens of Mechanism's mounts, called Deckmate, to create a Steam Deck-filled orb in the company's lobby. These developments highlight ongoing expansions in Valve's hardware ecosystem, with Mechanism providing complementary products from the outset.
