Facebook recently acquired Oculus VR for $2 billion, bringing the future of gaming to the mainstream.
Last week, Oculus VR announced the hiring of Michael Abrash as its Chief Scientist, a major industry vet leaving Valve. In the tweet, the Atman mentioned is Atman Binstock, who was also previously an engineer on Valve's virtual reality projects.
We're thrilled to welcome Aaron Nicholls (@aaronhelloworld) to the team! He'll be working out of the Bellevue R&D lab with Atman and crew.
