Bethesda and developer id Software have opened up registration for the upcoming closed alpha for Doom on PC, PlayStation 4 and Xbox One. This is not to be confused with the beta that will be made available for those who pre-ordered Wolfenstein: The New Order on or prior to its release on May 26, 2014. Id Software writes the following regarding the closed alpha:
"Series of development-driven tests designed to stress test the game's dedicated server infrastructure in a real-world consumer environment. It is not the beta, a demo, or representative of the final game."
There will only be one mode available in the closed alpha namely 6v6 team deathmatch.
