After a catastrophic demonic invasion brings the colony of Vega Prime to its knees, the Doom Slayer is once again called upon to do what he does best. Rip and tear, until it is done.

RS Oneshot: The forces of Hell tend to overcome their foes through brute force rather than well thought-out tactics or precise manoeuvres. By extension, little thought is given to the individual demons that make up their ranks.

Nate's just bought a new game, and it's multiplayer! Jake decides to stick around and play a bit with him, until, Nate spills his dank memery juices all over the damn Sega Genesis (which he's somehow playing with a keyboard), and sucks them both into DOOM! What kind of hellish memes will sprout from this? Read and find out! (Nate belongs to me, and Jake belongs to JoelJanova4.)

Doom has been gone for ten years after what Samuel Hayden did to him. He now returns to set things right, to come to Earth to go on a rampage against the demons who have now been changed and also the UAC, the ones who still think of him as a threat. Doom Slayer would have to fight everyone, in order to hunt down the one responsible for this.

M for safety (?)

There have been countless incursions carried out by the Umbral Plane and its denizens, not just the two written in slabs of stone and tales of ole. Gather around and listen as these stories are spun for those willing to partake in this regaling.
