Developers keen on getting hold of the Kunckles EV3 controllers will be able to do so in a couple of ways. Valve will be sending out more EV3 kits than the EV2 version, firstly by reaching out to previous EV2 recipients as well as developers who requested a previous kit. Those that have yet to request a Knuckles kit will have to wait until the EV3 form goes live, which should be soon.

Once you got your Knuckles EV3 controllers Valve has provided several developer resources to help get you started, including an updated SteamVR Knuckles Tech Demos (also referred to as Moondust). Additionally, the source files for the demo are freely available for studios to pick apart. For further updates on the Knuckles EV3 controllers keep reading VRFocus.
