Release date! May 20, 2014.
Preorders net you access to the DOOM beta! It's that last part that made a million ears perk up, and yes, Wolfenstein, you may consider yourself preordered. I don't think I've ever even played a DOOM multiplayer. Quake, sure. Don't care - it's a new DOOM, it's coming, and I'm dying to get my hands on it. id aren't giving away any details about DOOM, but there's a little evasive FAQ on their site, if you're curious.
Fortunately, The New Order looks like some good silly fun - so no skin off my nose, there.
