Doom Eternal

Doom Eternal is a sequel to Doom (2016), announced by Bethesda and id Software at the BE3 presentation on. Further information, including a gameplay reveal, was released at the 2018 QuakeCon convention keynote presentation on August 10. The game is currently targeted for release on November 22, 2019. The game will release simultaneously for PC, Xbox One, PlayStation 4, and Nintendo Switch. It was announced on March 19, 2019, that Doom Eternal will also support the game streaming service.

Details
According to id Software's Marty Stratton and Hugo Martin, the game features an even more powerful Doom Slayer taking on twice as many types of demons, with portions of the game set on Earth, Phobos, Hell, and (in a first for the series) Heaven. Among his new abilities, the Doom Slayer can execute a short-range dash up to twice in a row, even in mid-air, swing from poles and climb and jump between specially marked walls in a manner reminiscent of the  series. Special orbs bearing the Slayer's mark seem to replace the previous game's runes - one such featured in the August 10 gameplay reveal grants a "blood punch" ability that increases the player's melee power after a glory kill.

Mick Gordon is returning as the composer of the game's soundtrack, and has confirmed that the formula used in the previous game will be iterated upon for the sequel.

It has been confirmed by id Software in a QuakeCon questions-and-answers session that SnapMap will not return. However, a single-player pack is believed to be in the equation instead.

The game will utilize the next iteration of the id Tech engine, id Tech 7. While no concrete details have been revealed, id Software has claimed "ten times the geometric detail and greater texture fidelity." Early analysis of the gameplay footage reveals no dramatic visual changes from Doom 2016, but may have been added to the engine, allowing architecture close to the player to be adaptively tessellated, making it appear higher-fidelity.

Bethesda announced that the game will launch on the Steam platform for PC in a tweet posted on March 25th, 2019, putting to rest speculation that the game might be held as an exclusive for the Bethesda.net store.

At QuakeCon 2019, id Software revealed that the game, instead of Doomguy collectibles, will feature collectibles for all of the demons, which will also become available as action figures.

Collector's Edition
On June 9, 2019, Bethesda announced the Collector's Edition for Doom Eternal, including a wearable replica of the Doom Slayer helmet, a playable cassette tape with the Doom (2016) and Doom Eternal soundtracks, the game in a steelbook case, a lore book and a lithograph, and more.

Mechanics
A new dynamic model damage system called "destructible demons" will be a prominent feature of the game, allowing monsters to actively reflect the amount and types of damage they have taken. This system has tactical advantages as well, as it allows for weapons to be destroyed to disable certain enemy attacks.

Mobility has been expanded; a new dash ability has been added as well as wall-climbing and swinging on monkey bars found throughout the environment. The super shotgun also features a "meathook" that allows the Doom Slayer to grapple onto an enemy and pull themselves towards it.

Weapons

 * Melee attacks have the Doom Slayer punching his opponents instead of bludgeoning them using his currently held weapon.
 * Ballista, which appears similar in function to the original Gauss cannon, but with a new explosive bolt mod.
 * BFG-9000
 * Chainsaw, seemingly identical to its 2016 version.
 * Chaingun, which now fires energy projectiles similar to the previous game's pistol, but shares its ammo pool with the heavy cannon.
 * Combat shotgun, with the original Charged Burst replaced with an automatic fire mod.
 * Doom blade, an arm-mounted retractable blade used in glory kills.
 * Flamethrower, a shoulder-mounted napalm-firing alternate weapon that sets enemies ablaze.
 * Grenade launcher, a shoulder-mounted alternate weapon which seems to replace the frag grenade.
 * Heavy cannon, with a scope and a micro-missile mod, similar to the original heavy assault rifle.
 * Plasma rifle, with a new appearance inspired by the classic plasma rifle and with the Stun Bomb mod replaced by a beam-firing mod which slows down and damages enemies, making them explode with splash damage if killed.
 * Rocket launcher, with new demonic appearance and a returning Remote Detonation mod.
 * Super shotgun, which now includes an underslung bayonet-like device currently known as the "meat hook". One of the functions of this device is grappling onto enemies from afar.

Other weapons known to be part of the game but for which not many details are yet available include a sword which appears similar to the Crucible, but is a distinct artifact, according to Hugo Martin.

Multiplayer
A new multiplayer feature called "Demon Invasion" (also referred to as "Slayer hunting parties") will be available, allowing players to go on raids into other players' campaigns to play as demons in a manner similar to the first game's demon rune. Participation is strictly optional.

While it was stated at QuakeCon 2018 that traditional multiplayer would be included as well, this time being developed in-house at id Software, it was later explained that ordinary modes such as deathmatch are not currently planned for inclusion. According to the E3 2019 announcement, there will instead be a "Battlemode", where one player controlling the Doom Slayer fights two demons controlled by other players, who can also summon weaker AI-controlled demons such as former humans and drop hazards. The playable demons are the revenant, mancubus, marauder, pain elemental, and arch-vile.
