You may still be able to get into the Doom alpha
There's still a chance you could be playing the Doom alpha with this weekend.
The second closed alpha for Doom has kicked off on PC, PlayStation 4, and Xbox One. If you didn't register for the beta, or if you didn't pre-order Wolfenstein: The New Order, there's still a chance.
Bethesda revealed a few hours ago on Facebook there are limited slots available across all platforms, before quickly announcing that only PlayStation 4 and Xbox One keys remain.
All you need to do is head to the PS4 page or Xbox One page, choose your language and region, and fill in your email address.
I've just tried it for Xbox One. You will receive an email only if you're selected, but it's worth a try.
