Developed by id Software, DOOM® Eternal is the direct sequel to the award-winning and best-selling DOOM® (2016). Experience the ultimate combination of speed and power with the next leap in push-forward, first-person combat. As the DOOM Slayer, return to take your vengeance against the forces of Hell. Set to an all-new pulse pounding soundtrack composed by Mick Gordon, fight across dimensions as you slay new and classic demons with powerful new weapons and abilities.

Gameplay

Players once again take on the role of the Doom Slayer, an ancient warrior who battles the demonic forces of Hell, from a first-person perspective. The game continues its predecessor's emphasis on "push-forward" combat, encouraging the player to aggressively engage enemies in order to acquire health, ammo and armor. The player has access to various firearms, such as the Combat Shotgun, Super Shotgun, Heavy Cannon, Rocket Launcher, Plasma Rifle, BFG 9000, and Ballista. Melee weapons such as a chainsaw, the "Crucible Blade" energy sword and a retractable arm-blade can also be used. The arm-blade provides the opportunity for a larger variety of quick and violent "glory kill" executions. The Super Shotgun is now equipped with a "Meat Hook", which slingshots the player towards an enemy, functioning as a grappling hook in both combat scenarios and environmental navigation. A new Equipment Launcher with the ability to lob grenades and ice bombs that also dons a Flamethrower that provides armor from burning enemies is now part of the Doom Slayer's armor. New movement mechanics such as wall-climbing, dash moves, and horizontal bars to swing from will also be introduced.

In a demo build unveiled to the public in January 2020 further new mechanics were also revealed, including high difficulty Slayer Challenges, additional upgrade resources including Sentinel Crystals, and the ability to take control of some enemy units.

Creative director Hugo Martin has stated there will be twice as many demon types as in the 2016 reboot. There are new types of enemies, such as the Marauder and Doom Hunter, while others, such as the Pain Elemental, Arachnotron, and Archvile, will be reintroduced from previous Doom entries. A new system called "Destructible Demons" is featured, in which enemies' bodies become progressively destroyed and deteriorated in combat as they suffer damage. Through this system, certain parts of a demon's anatomy can be destroyed to eliminate their ability to use their stronger attacks. There is also a new lives system. During gameplay, players can collect 1-up items (which look like green helmets) scattered around the environment. When the Doom Slayer perishes in combat, he will respawn where he died if he has spare lives, instead of restarting at the nearest checkpoint.

The game will feature an asymmetric multiplayer mode called "Invasion", in which players can join others' single-player campaigns, fighting against them as demons. This mode can be turned off by players who wish to play the game solo. However, "Invasion" will not be present at launch but will instead be added as a free post-release update. In addition to Invasion, the game features other standard multiplayer modes.
