'Doom Eternal is a first-person shooter game developed by id Software and published by Bethesda. The game was set to be released on November 22, 2019 for the Nintendo Switch but it was delayed into 2020. It is the fifth main title in the Doom series and a direct sequel to DOOM.
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 and ammo. The player has access to various firearms, such as the Combat Shotgun, Super Shotgun, Heavy Cannon, Rocket Launcher, Plasma Rifle, 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. Armaments including missiles, grenade launchers and flamethrowers can also be attached to the Doom Slayer's armor. New movement mechanics such as wall-climbing and dash moves will also be introduced.
Creative director Hugo Martin has stated there will be twice as many demon types as in DOOM. 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. 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. In addition to Invasion, the game features other standard multiplayer modes.
Following an unknown time frame after DOOM, the Doom Slayer returns once more to combat the forces of hell. Earth has been overrun by the demonic forces, transforming it into a flesh and bone monstrosity. The Slayer returns to save them once more, but he incurs the wrath of Heaven in the process.
