Bethesda announced Doom Eternal, the sequel to the 2016 title. This time, Doomguy, sets foot on an Earth turned upside down by hell. There's a lot of demons running around and a lot of tentacles sprouting from the ground, squeezing and crushing, and maybe out to stab you in the back. It's really creepy stuff.
Bethesda said they will reveal more details on QuakeCon - ZeniMax Media's own convention that promotes all of Bethesda Softworks' stuff, because they own Bethesda.
