DOOM Equestria

Private Buckshot Blast had just arrived at Utopia Planitia for his new assignment. Fresh out of the academy, he was surprised to see that he got assigned to Mars. He expected to get assigned to the Moon or even Phobos. But Mars?

He never really wanted to enlist. He grew up as a parasprite hunter on a small farm just outside of the city limits of Trottingham. He and his brother, Hayseed, were getting ready to take over the farm when they came home to a burning house. They found their dead parents in the shed. Their Father appeared to have been killed by a chainsaw, and their Mother had been raped and shot.

Having nowhere els to go, they went to live with their best friend, Dexter. Dexter was a dragon that was a descendant of Rarity and Spike. After a couple years, Dexter enlisted. The brothers, of course, had to go with him. With some luck, they all got assigned to platoon G-46. A small platoon with only five marines, four unicorns, and one dragon. Unicorns being to only ponies able to wield a gun. Pegasi typically got scouting missions wile earth ponies were trained in advanced hoof to hoof combat.

"Platoon G-46 please report to marine command center to receive you orders.", said a loud speaker in the shuttlebay.

"That's us!", said Dexter. "Maybe you can finally get rid of that old man gun Buckshot." The other marines always made fun of buckshot for bringing his double barreled shotgun. He always tried to wave it off like nothing, but it often got to him. On the way to the Marine Command Center, they passed a large platoon guarding two important looking ponies. One was a young white mare with a purple mane and a short tale. The other pony was an old stallion with grey fur and a black mane.

"Who are those ponies?", asked Hayseed in his country accent.

"That's Aurora Foul and her assistant, Dr. Batruger.", answered Dexter. "They're in charge of the Lazurus project." They finally arrived at MCC. They went through automatic sliding doors that made a slight squeal what they moved.

"Good afternoon recruits.", said a buff, blue stallion with a large scar on the side of his face, and an artificial leg. "I am Lieutenant Colonel Ass Kick. I am here to give you your first assignments. I've read all your records and they're all exemplary. So I'm not going to give you an easy one. Two Hell Knight demons have escaped in section 48-A. Your job is to track them down. They've already killed ten marines, so stay on your toes. If you see them, shoot to kill."
