One of the more exciting announcements for me coming out of E3 was the fact that Fallout 4 will be coming to the HTC Vive. I wasn't able to get to E3 to try it out, but you can see one of the principal actors do it.
Brian Delaney is the voice of the Sole Survivor in the game and he got a chance to step into the Commonwealth with the Vive. The demo had him at Red Rocket, checking out the landscape, and facing off against a Deathclaw with hilarious results.
I can't wait to get this in my hands.
