Valve – which runs the Steam game store and made the legendary Half-Life series – already makes a VR headset for hardcore gamers who care to tether themselves to a beefy PC for an immersive experience.

Valve has finally revealed Steam Frame, the company’s second VR headset. Though it’s quite a departure from Index—the company’s first headset released some six years ago—Valve says Frame is an “evolution” of Index.
