Bethesda has opened up registration for Doom's multiplayer closed alpha on PC, PS4 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 before 26th May, 2014.
This closed alpha is a "series of development-driven tests designed to stress test the game's dedicated server infrastructure in a real-world consumer environment," developer id Software stated on the registration page. "It is not the beta, a demo, or representative of the final game."
The closed alpha will entail one map, Heatwave, an industrial-themed stage full of narrow hallways and tight chambers.
There will only be one mode available with six vs six team deathmatch. The map will have one "Demon Rune" that temporarily transforms the player into a jetpack-wearing dual rocket launcher-wielding demon named Revenant.
To combat Revenant, there will be one power weapon called the Gauss Cannon. This deadly weapon can take down a foe in one shot, while its alternate firing mode allows its user to see through walls. It's recommended to be used against a demon, as it has very limited ammo. Once it's out of shells you'll have to wait for it to reappear on the map.
Other weapons in the closed alpha will include the Vortex Rifle, Super Shotgun, Repeater, Rocket Launcher, Static Cannon and Plasma Rifle. Equipment items will be limited to a Personal Teleporter and Frag Grenades.
