This is a crossover of Halo and Doom and Metroid it looks pretty amazing as soon you start to read it because gotten some references from the halo books regarding the Spartans.

A combination of both of these games Can they stop the threat of the Covenant and the Demons of Hell

What would you do to make up for past mistakes? Some people spend a massive amount of energy to do so, but that energy can either award a blessing, or a curse.

When all seems lost and the endless hordes once again pour forth from Hell, the Master Chief finds some help from an old legend wielding a double-barreled sword of vengeance. Lite spoilers for some Halo: Infinite lore. One-shot.

Imagine Halo CE (and possibly more) but Master Chief is replaced with Doom Guy, how will Doom Guy deal with his new enemies in the form of the Covenant? (rated T for gore and minor language) (Eventually I will make a revision since the writing kinda sucks und ist boring.)

Being a college student is hard. You suffer from sleep deprivation, you have to deal with the stress of knowing you probably won't be able pay off your student loans, and you don't get enough free time to hang out with people as much as you used to. When Doomguy arrives at Hogwarts he is ready to rip and tear, but will college rip and tear Doomguy?

Oneshot: More than one culture in the galaxy had conceived of something resembling angels. More than one culture had conceived of something resembling Hell. Coincidence? Or was there truth behind the myth?

The Covenant fear Demons, and Demons fear Doomguy.

The Slayer is on Sanghelios as an ambassador for all of mankind he falls in love with someone and the plot thickens I will change this later but I got the gist (REVAMP IN PROGRESS!)

"This one is machine and nerve, and has its mind concluded. This one is strength and death, and cannot be eluded." There are those that are called Demons, and there are those that are called Slayers. And when the time comes that they are banded together, those that rise against them will fall just as quickly. Alternatively titled "Universal Doom: Chapter 20".

The Doom Slayer had finally done it, he had obtained The Crucible and had finally closed the portal to Hell. All was well, right? Wrong. After Samuel Hayden betrayed him, The Doom Slayer finds himself once again in a crypt on Mars, except this wasn't the Mars he knew... Now there are ferocious aliens attacking humanity, and The Slayer must rip and tear, just like before.

With a alliance secured with the Sangheili, the Doom Slayer & the Arbiter make haste towards the Sacred Icon. Meanwhile on High Charity... Jeff & Gary help Zuma fulfill a personal mission while learning more about the Covenant during their adventure.

After saving another galaxy from Hell's invasion by Emperor Palpatine. The Doom Slayer was given the chance to go home, but a glitch affected the portal sending him along with Jeff & Gary into the Halo universe.

Hell no longer could Deal with the Doomslayer. He was too much. They also feared killing him as to be trapped with his soul. So they sent him away. A drift in the stars for hundreds of years till eventually he was discovered by Infinity.

This was originally intended to be posted on Who Would Win? on a thread about Doomguy(2016) vs Master Chief. I hope you enjoy it and please leave a review if you like it!

Master Chief and Cortana ends up being caught in the center of a fight between the UAC on planet Argent and the Covenant Remnants, leading the covenant here by a being disguised as a Promethean who wishes to get to this planet and reach to this gate which might end up bringing hell to both races. If Chief doesn't stop him then he will bring an army worst than the Flood.

As the Human-Covenant War rages on, the hubris of humanity opens a gate into the bowels of the nightmarish realm of Hell. Only one man can go knee-deep in the dead to stop the invasion on the red planet and save humankind from a second invading force. Cover art by Superhermit from deviantArt.

An alien race has brought together 52 of the worlds greatest heroes, anti-heroes, survivors and badass people from the history of Games, Movies, TV, Comics and Books to fight it out in a massive arena called the Voidatorium outside real time and space. Amongst them is the infamous Doomguy and Master Chief...at the end of the day only one can survive.

The UAC accidentally opens portals to Hell when experimenting in teleportation. They also open portals to a parallel dimension where humanity fights alien zealots to survive and Master Chief dives into Hell with the Corporal (Doomguy) to find the legendary Soul Cube. rated M for language, blood & gore.

doomguy is late for shootan school! will he make it in times? find out

The UNSC unwittingly unleashes hell upon themselves while they experiment with teleportation technology. Rated T. Please read, and review!

A planet under siege of the Covanent is burned under they're wrath, but something darker and more sinister lurks below the private enterprise of the U.A.C.. Note this my first story so advice on writing and how to proceed with the story will be greatful.

Oneshot: It was unpleasent to be on Mars in the final days of the Human-Covenant War, waiting for the Brutes to descend on the red planet. It was even more unpleasent when an unregistered dropship came flying by, belonging to something called the UAC...

Two years have passed since the end of Halo 3, Master Chief and Cortana are considered lost to space forever. All seems at peace until an enemy far greater than the flood arises. Now the Master Chief and a nearly rampant Cortana must uncover the mystery.
