Doom publisher Bethesda Softworks is now accepting registrations for the game's closed alpha, the company announced today.

Registration is currently open only to those who pre-ordered or purchased Wolfenstein: The New Order before May 26, 2014, and will be available on PlayStation 4, Windows PC and Xbox One. If you qualify, you can head to the game's official website to input your registration code.

The alpha is designed as a "stress test" for the game's multiplayer servers, according to Bethesda. It will offer one mode, a six-versus-six deathmatch, as well as a single map: Heatwave. A limited set of weapons and equipment from the full game will also be available to try out.

This build of the game differs from its upcoming beta, which will similarly be available to those who pre-ordered The New Order. No release date has been confirmed for that yet.

We went hands-on with the multiplayer side of Doom during this year's QuakeCon in June. The game is expected to hit stores in 2016.

You can also get a taste of Doom's multiplayer courtesy of its E3 2015 demo, seen below.
