At gamescom Bethesda revealed a new trailer for the new Doom Eternal DLC entitled The Ancient Gods. In the trailer we heard the devs giving a developers overview of the trailer and gave us some insight into what inspired the DLC.
The DLC is centered around Demons having access to many portals giving them access to new locations which you will play in when you play the DLC. The trailer also showed off the hell swamps which is a location which looks totally different to any of the base games locations.
The trailer also showed off a homage to the movie Ghostbusters, the game pays homage to it by having lasers which may or may not cross.
