If you've been itching to try out BioWare's jetpack loot shooter, Anthem, then it's time to pull that slot machine lever and hope for the best! Sign ups are currently open to participate in a closed alpha, but the window on this very limited. The sign ups end on Monday, December 3, and the alpha runs on December 8 and 9, so if you manage to get in, be sure to clear your calendar next weekend.
All the details and answers to a variety of questions around this can be found over on the official support page, while the sign-ups are done through the EA Community Playtesting site. It's first come first served, though, so if you're interested, I'd head over there now. Finally, it's also worth mentioning that there is a very strict NDA on the Alpha and you really don't want to break those. The alpha will be available on the PC, PlayStation 4, and Xbox One, so at the very least you'll have your platform of choice.
If you don't get in, then the good news is that you don't have too much longer to wait. Anthem is still slated for a February 22 release date, which is just under 3 months from now. Hopefully BioWare's gamble will pay off for them.
