The Doom Slayer

I ran up to the incapacitated SpiderMastermind. I forcefully shoved my foot into the bottom of it's jaw and lifted up the top part of its lip. I pulled out my BFG, which was found in the Advanced Research facility. I shoved the BFG into the Spider Mastermind's mouth. Holding down the trigger so it could charge up. The BFG charged up in 2 seconds, the BFG's containment fields couldn't hold the energy any longer. It released the green energy into the Spider Mastermind's mouth. A loud explosion could be heard of guts and the BFG blast as it went right through the Spider Mastermind's brain. I backed up away from the dead Spider and put away the Big Fucking Gun. I stood there waiting for something to happen, a blue light shines upon me and my helmet's HUD said,

"Tethers activated"

I instantly teleported back to the UAC Mars Base. I tried to move but I was stuck, then I heard a familiar voice.

"It's over, you stopped the invasion and closed the portal, but it's come at a price. Argent...VEGA....this entire operation."

Samuel Hayden continued talking,

"You see I've watched you worked, come to understand your motivation. You think the only way is to kill them all, leave nothing behind"

The robot continued talking while making hand gestures and getting closer,

"...And you may be right. But we can't just shut it all down! Without Argent energy it will be worse. I don't expect you to agree..."

Samuel Hayden then used the tethering system to take the Crucible from my possession,

"But with this, we can continue our work!"

Samuel Hayden said, raising the glowing Crucible up,

"I am not the villain in this story, I do what I do because there is no choice!"

"Tether coordinates applied", a female robotic voice said

"Our time is up, I can't kill you. But I won't have you standing in our way!"

The Crucible had a blade of red energy expand from the top. Making the crucible a Argent Sword. A sword made of Hell's energy.

Samuel Hayden turned around and walked away. I started levitating up and my vision started to turn a bright blue.

Doomed.
