9 Minutes gameplay of Doom Eternal from IGN.
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 several asymmetric multiplayer modes, including “Battlemode”. This game type is a 2v1 PvP multi-round match where two player-controlled demons take on one fully loaded Slayer. There will be five playable demons at launch, with more to be included in free updates post-launch. The five initially available demons are the Marauder, Mancubus, Pain Elemental, Revenant, and Arch Vile. In addition to regular attacks, each demon has a “summoning wheel”, which contains a selection of four additional abilities. These can range from AoE box effects[further explanation needed] to spawning in higher tier NPC demons. An additional mode, called “Invasion”, is also in the works, and is expected to be released as a free post-launch update. In this mode, players will be able to 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.
Also new to the game is the hub area, called “Fortress of Doom”, which players can visit between missions, containing a number rooms with upgrades and gear locked behind doors.
