### Doom 2016

It is stated that this version of Doom is actually an origins story. Doomguy awakes taking note that he's been chained to an altar in a UAC basement on Mars, and realizes that something is amiss, escapes imprisonment and gains his Praetor Suit. Making his way across the Martian surface, he enters an industrial building that houses a satellite. After re-aligning the dish array, he hopes to learn the source of the demonic invasion, and preps himself to stop it.

Doomguy then finds himself eventually allying himself with Doctor Samuel Hayden among with his A.I. called VEGA to put an end to Olivia Pierce and her plans. Doomguy eventually slays her the moment she changes into a Spider Mastermind and Samuel betrays him shortly afterward.

### Doom Eternal

Eight months after the events of 2016's DOOM, Earth has been overrun by demonic forces, wiping out 60% of the planet's population, under the now-corrupted Union Aerospace Corporation. What remains of humanity has either fled Earth or have banded together as part of ARC, a resistance movement formed to stop the invasion but have gone into hiding after suffering heavy losses. The Doom Slayer, having previously been betrayed and teleported away by Dr. Samuel Hayden, returns with a satellite fortress controlled by the AI VEGA to quell the demonic invasion by killing the Hell Priests; Deags Nilox, Ranak, and Grav. The priests serve an angelic being known as the Khan Maykr who seeks to sacrifice mankind. The Slayer teleports to a destroyed Los Angeles and kills Deag Nilox, but the Khan Maykr teleports the two remaining priests to unknown locations, forcing the Slayer to continue searching.

After retrieving a celestial locator from the Sentinel world of Exultia, the Slayer travels to Hell to retrieve a power source from a fallen Sentinel known as the Betrayer. He warns the Slayer that humanity's time has come before giving him the power source and a special dagger. VEGA directs the Slayer to a citadel in the Arctic where Deag Ranak has taken refuge, and the Slayer kills him after defeating his guardian Doom Hunters.

In response, the Khan Maykr moves Deag Grav to a hidden location and accelerates the invasion of Earth. Forced to change tactics, the Slayer destroys the Super Gore Nest in central Europe, where the invasion began. With no leads on finding the last Hell Priest, VEGA suggests finding Dr. Hayden, who knows the location of Deag Grav. The Slayer makes his way to an ARC compound where he retrieves Hayden's robotic shell, as well as the Crucible before facing a Marauder, a demonic Sentinel sent to stop the Slayer.

Upon uploading Hayden's mind into the fortress, he reveals Deag Grav is hiding on Sentinel Prime. With the only portal to Sentinel Prime located in the ancient city of Hebeth in Mars' core, to which there is no immediate access. The Slayer then travels to a facility on Phobos where he uses the BFG 10000 to shoot a hole in Mars, which he uses to reach Hebeth. After reaching Sentinel Prime, flashbacks reveal the Slayer to be Doomguy. Found badly wounded by Sentinels, Doomguy was brought before the Deags and was forced to fight in a gladiatorial arena. Impressed by Doomguy’s ruthlessness in battle, the Deags inducted him into the Sentinels, while the Khan Maykr inquires into Doomguy's knowledge of the Demons. In the present, the Slayer finds Deag Grav in the arena and defeats a massive demon known as the Gladiator. Despite knowing that it is against Sentinel law to murder Deag Grav on sacred ground, the Slayer kills him anyways and returns to the fortress.

Upon his return, the Slayer's fortress is shut down remotely by the Khan Maykr to prevent any further interference in her plans. She reveals her intentions to resurrect the demon world-eating super-predator, the Icon of Sin, to consume mankind before having the Slayer attacked by demons. Surviving the ambush, the Slayer uses the demonic Crucible's latent Argent energy to reactivate the fortress and travels to Argent d'Nur to retrieve his own Crucible from his time in the Sentinels.

* **Fire Axe:** Doomguy can use this Axe to beat down zombies at close range in addition to break down beaten-up doors (Doom RPG).
* **Fire Extinguisher:** While primary used to put out fires, this is very effective against fire-based enemies such as Lost Souls & Arch-viles (Doom RPG).
* **Chainsaw:** While their has been no known use for the Chainsaw being on Mars didn't stop Doomguy from using it, he can use this weapon to cut through many demons at ease as it's capable of dealing constant damage upon contact.
* **Ionized Plasma Levitator:** This unusual weapon allows Doomguy to hold certain objects above the ground for a limited time and can throw them with great force in addition to the fact it can also allow him to grab incoming fireballs thrown by enemies, reach otherwise inaccessible pickups, \destroy certain enemies and remove obstacles in the player's path.
* **Frag Grenade:** Doomguy can throw this frag grenade once every ten seconds, he can throw a total of two of these and only wait for twenty seconds to throw two at a time again.
* **Hologram:** Doomguy can create a hologram that not only acts as a dummy but can even shoot. He can use a hologram once every ten seconds and can use a total of two every twenty seconds at a time.
* **Siphon Grenade:** This functions similar as the Frag Grenade as it deals damage to enemies within the radius. In addition, the Siphon Grenade not only deals damage to enemies but also partially heals Doomguy as well.
* **Pistol (UAC EMG Sidearm):** In the 2016 version of Doom, Doomguy can shoot this at an unlimited amounts of times as he wishes. As soon as he fires this, it compresses up to 4 megawatts of Argent Energy into a hardened plasma gel as it launches the slug at high velocity. The gel has the same impact properties as conventional ammunition thus making it feel like an actual firearm.
	+ **Charge Efficiency:** Doomguy manages to modify the Pistol to decrease the duration period it takes to power up a Charged Energy Shot.
	+ **Quick Recovery:** Doomguy also managed to modify the Pistol to decrease the recovery duration period after he fires off a Charged Energy Shot.

Doomguy can only fire off these rounds whenever he's zoomed into his chosen target.
	+ **Micro Missiles:** This multi-chambered cylinder that is located under the primary barrel is something that Doomguy can load up to six HMX missiles. The small-but-deadly rockets are designed to deliver multiple payloads to even a single target and can subdue multiple targets within a tight kill-zone.

He can fire endlessly so as long as his Armor remains at least at 75% and above upon using the Rich Get Richer Rune.
* **Plasma Rifle:** This standard issue military weapon is capable of delivering a rapid salvo of plasmoids that deal not only impact but also thermal damage to Doomguy's chosen targets.
	+ **Heat Blast:** This modification allows Doomguy to cause the Plasma Rifle to absorb residual thermal energy thus instantly transferring the heat to the borosilicate diffusion chamber. As soon as the meter is full will allow Doomguy to unleash a heat wave from the end of the weapon that deals localized damage in addition to the possible chance it will create a pressure wave that will knock back targets.
		- **Super Heated Rounds:** This upgrade allows the Plasma Rifle with the Heat Blast Modification causes the heat within the Heat Blast Modification to build up faster then normal, taking at least 3 seconds for Doomguy to max out the Heat Blast's heat bar thus allowing him to unleash the Heat Blast.

		- **Expanded Threshold:** This upgrade allows the Plasma Rifle with the Heat Blast Modification further increases the amount of heat that can be contained within the Heat Blast Modification itself, thus allowing Doomguy to deal even more potential heat-based damage from it.
		- **Heated Core:** This upgrade allows the Plasma Rifle with the Heat Blast Modification to generate heat on a passive scale, thus making it so that Doomguy won't have to use up ammunition to build it up. It takes the Heat Blast Modification 10 seconds to build upon its own without Doomguy having to fire the Plasma Rounds.
	+ **Stun Bomb:** This modification for the Plasma Rifle allows Doomguy to fire off a powerful pulse that will stun near-by targets caught in the radius. The modification requires cooling between uses.

		- **Chain Stun:** The moment Doomguy manages to kill his chosen targets while they remain under the effects of the Stun Bomb will release a secondary stun that will detonate and stun other targets near by if any.
* **Gauss Cannon:** This weapon is the result of the basis for numerous industrial projects over the years with the Argent Tower being one of those projects. The Gauss Cannon is capable of scoring near perfect accurate hits due to it's aerodynamic design of the projectiles with the ammunition being cheap and readily available.
	+ **Precision Bolt:** This standard telescopic sight is used to allow to further improve it's already near-perfect accuracy at long ranges. Doomguy can accumulate additional magnetic charge within it's launch chamber and when released will fire off the flechettes as an even greater speed. A fully charged flechette is almost seemingly unstoppable as it will pass through even multiple targets within Doomguy's sight.
		- **Energy Efficient:** This upgrade allows the Gauss Cannon with the Precision Bolt Modification to reduce the duration period to charge up the bolt to maximum power. Further more, it also reduces the duration period between shots as well.

	+ **Siege Mode:** This allows Doomguy to shoot a plasma beam once fully charged. Because of it's precise nature of the modification itself, safety valves prevent the weapon itself from discharging until the Argon has been fully ionized. While Doomguy charges this also prevents him from moving anywhere until he manages to release the plasma beam which is capable of penetrating up to multiple targets at once thus producing a concussive blast at the final point of impact.
		- **Outer Beam:** This upgrade allows the Gauss Cannon with the Siege Mode Modification a devastating area of effect around it, thus dealing damage to other enemies caught within the area of effect.

It is said that this is what lead the UAC to build and mass-produce the Plasma Rifle.
* **The Unmaker:** Intended to be a demon-tech weapon as it was made out of demon bones, this weapon is designed to destroy demonic beings. Doomguy enjoys the benefits of it's spreadfire function in addition to the fact it doesn't pose any recoil openings, allowing Doomguy to take down even his most powerful targets.
* **The Soul Cube:** Due to the fact it's an ancient Martian artifact, the Soul Cube can only be activated the moment Doomguy kills at least five targets so as long as they have a soul. The Soul Cube will always attack a enemy with the most amount of health in addition to dealing splash damage to adjacent enemies. It is also capable of restoring some health to Doomguy as well.
