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. Previously planned for release on November 22, 2019, the game has been delayed, and is currently targeted for release on March 20, 2020. The game will release simultaneously for PC, Xbox One, and PlayStation 4. It was announced on March 19, 2019, that Doom Eternal will also support the game streaming service. While originally slated for a simultaneous release on the Nintendo Switch, as of the October delay it was stated that the Switch version will release at a later date which still remains unspecified.

Story
Set 8 months after Doom 2016, about 60% of the Earth has been conquered by the demonic invasion. With the Earth military helpless in turning the tide of the battle and the majority of the human population killed during the first month of the invasion, star ships called ARCs are created to preserve humanity and evacuate them into orbit.

It is at this time that the Doom Slayer returns from Hell to save humanity by slaying the three treacherous Hell priests, whom the Khan Maykr has sent to Earth to command the invaders. After the Slayer kills all the Hell Priests, the Khan Maykr decides to resurrect the Icon of Sin. The Slayer goes to get his Crucible blade and most probably kills the Icon.

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, Mars, 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 are like the previous game's runes, but they give rune powers without challenges..

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 is confirmed that songs from previous games in the series will again be sampled.

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.

 * Khan Maykr

Two gigantic demons have been shown, one resembling a scaled-down Titan (referred to in IGN First gameplay as "Hell Barge") and the other remaining mostly unseen aside from its forearm. Judging by the size of the forearm, the second demon is apparently as large as a tall building. Fans have speculated that the larger demon might be the Icon of Sin itself, but this remains unconfirmed; it has been seen that the Icon does occur in the game, however, as pre-release footage indicates the Khan Maykr desires to resurrect the Icon of Sin under her command. Both of these large demons have been spotted in the second "gameplay" trailer, with the Icon of Sin-like demon shown nearly completely (arms, torso and head).

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. You can dash twice (even in midair) before needing to recharge, and there are dash recharge items in the environment. The super shotgun also features a "meathook" that allows the Doom Slayer to grapple onto an enemy and pull themselves towards it. With the increased movement options, traversal sections have become more complex, incorporating various hazards such as flaming chains, falling platforms and damaging fields. Unlike the previous game, falling in these sections will instantly return the player to their last position at the cost of a few points of health.

Occasionally an "empowered demon" may appear in a player's single-player campaign, bearing the name of a player that was killed by that demon in their own play session. Such demons are stronger than normal, but give special rewards when defeated. Empowered demons are strictly optional.

Also, the Doom Slayer will have a personal headquarters called The Fortress of Doom, a castle-like space station orbiting the Earth which will serve as a in-game hub. Sentinel Batteries are scattered across the game and can be collected to bring the Fortress online, unlocking more areas to explore. Another feature of the Fortress is 'Ripatorium', a demon prison that is used as a training ground.

Weapon Points, Rune Perks and Suit Upgrades all make a return, containing a mixture of familiar and new upgrades. Sentinel Crystals replace Argent Cells as the method for upgrading the player's health, armor and ammo.

Secret Encounters and Slayer Gates are optional combat encounters in each level. Slayer Gates are unique in that they are comparatively intense encounters that can only be accessed by finding secret keys hidden in the maps.

Due to the increased difficulty from the previous game, extra life powerups can be found scattered across the game. These will allow the Doom Slayer to immediately respawn if killed instead of being sent back to the last checkpoint.

The Codex returns from the previous game, but now has the added feature of listing enemy weaknesses. Instead of datapads, lore is scattered across the game world in the forming of floating burned pages.

Weapons

 * Melee attacks have the Doom Slayer punching his opponents instead of bludgeoning them using his currently held weapon. Glory killing enemies fuels his "Blood Punch", a supercharged punch that deals damage in an area in front of the player.
 * Ballista, which appears similar in function to the original Gauss cannon, but with a new explosive bolt and "destroyer blade" mods.
 * BFG-9000, which is now a part of the weapon wheel.
 * Chainsaw, seemingly identical to its 2016 version. It is referred to as the Mixom "Dopesaw", versus the previous game's "Painsaw".
 * Chaingun, which now fires energy projectiles similar to the previous game's pistol, but shares its ammo pool with the heavy cannon. Instead of wind-up mod, you can bring up a shield.
 * Combat shotgun, with the original Charged Burst replaced with an automatic fire mod, and the explosive shot being replaced with a sticky bomb.
 * Crucible - Used to instantly glory kill enemies. Functions similarly to the Chainsaw, but every enemy type costs one charge and slain enemies drop health instead of ammo. It is a distinct artifact from the Crucible in Doom (2016), according to Hugo Martin.
 * Doom blade, an arm-mounted retractable blade used in glory kills.
 * Flamethrower, a shoulder-mounted napalm-firing alternate weapon that sets enemies ablaze. Burning enemies drop armor shards.
 * Ice bomb, a projectile fired from the shoulder which freezes enemies temporarily.
 * 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 Microwave Beam 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 hookshot-like device currently known as the "meat hook" which is used to grapple onto enemies from afar.
 * The Unmaykr, a secret weapon which requires six Empyrean Keys to be used in the Fortress of Doom. May be related to the Unmaker from Doom 64.

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.
