Doom's next expansion is coming on October 20.

Doom Eternal expansion The Ancient Gods Part One arrives October 20

Bethesda and id Software announced that the first single-player campaign expansion for Doom Eternal is The Ancient Gods Part One, and it will debut October 20. It appeared during Geoff Keighley’s Opening Night Live streaming event at Gamescom 2020 today.

The Ancient Gods will focus on the imbalance of power in heaven and how our favorite hero, the Doom Slayer, fits into that. If you are a completionist and read all of the text-based lore in Doom Eternal, you’ll probably know something about what this means.
