The Lab is a free, semi-Portal-themed collection of minigames and vignettes from Valve, designed to show of the capabilities of their new VR headset, the Vive. It’s out now, but clearly most of you won’t be able to try it – even if you ordered a Vive, you’re weeks or more away from receiving it. Given this is, in theory, the first new Valve game in quite some time, I thought I’d tell you all about it.
