Doom Eternal is a 2020 first-person shooter game developed by id Software and published by Bethesda Softworks. The sequel to Doom (2016), and the seventh game in the Doom series, it was released for PlayStation 4, Stadia, Windows, and Xbox One on March 20, 2020, with a port for Nintendo Switch released on December 8, 2020, and versions for PlayStation 5 and Xbox Series X/S released on June 29, 2021. Set some time after the events of the 2016 game, the story follows the Doom Slayer once again, on a mission to end Hell's consumption of Earth and foil the alien Khan Maykr's plans to exterminate humanity. Along with the single-player campaign, a multiplayer mode, Battlemode, was introduced. In this mode, players can either play as the Doom Slayer or as a demon, and fight until either the Doom Slayer defeats the demons, or vice versa. A horde mode was added in October 2021. The Ancient Gods, a two-part standalone campaign DLC set after the events of the main game, was released between October 2020 and March 2021.
