Ace gripped the shotgun as tight as basic levitation magic could. He trotted down another corridor, broken glass in every window. A torso with one of the aliens on it laid on the ground, dried blood trailed off the severed half. The creature squirmed and pulsated on the ponie's head. He cantered on. The corridor ended at a portion of raised concrete. Hoofrails stood on the elevated platform, a few science team ponies galloped over to a group of six soldiers.
"Wait, don't shoot! We're with the science team!" A mare shouted, galloping ahead of the rest.
A soldier slammed a hoof into her snout, blood trailed with the hit as she spun three hundred sixty degrees and fell over. As she tried to get back up shakily, the soldier shot her in the back of the head. She slumped over. Blood pooled on the ground.
"Nopony cares who you are!" He yelled.
The other scientists, including Twilight started turning the other way when the rest of the soldiers started shooting.
Ace galloped faster than he previously thought anypony could go. He fired buckshot into the head of a soldier, almost blowing it off completely. He picked up the soldier's assault rifle and fired two magazines into the two adjacent, the other three turned to retreat. Ace levitated the shotgun and fired both of the barrels into two, the perfect distance for the bullet's spacing. They flew forward from the blast.
The last soldier galloped away before Ace could get him.
The lavender mare, whom he now recognized as Twilight Sparkle stared at him wide-eyed, the other two had already left.
"Wasn't the Equestrian military supposed to rescue us?" He asked, mostly calm as he retracted the now blood-soaked helmet.
"...Ace!?" She recognized after a second.
"Stay here, I need to make sure you can escape from the facility safely. Take this, I'll come back for you." He instructed as he dropped a pistol in front of her.
She stared at him silently, mostly in shock as he trotted off.
He trotted down the corridor the soldier galloped through.
The soldier looked over to see Ace wielding a shotgun.
"Somepony get me a medic!" The soldier shouted while bleeding out, sitting on the ground. Seemingly hit by the previous shotgun blast, he breathed hard as his neck was filled with holes and gushing blood.
Ace took out the assault rifle and shot him in the head, putting him out of his pain.
More soldiers galloped over from further down the hall. They saw their fallen comrade, blood painted the wall behind his head. They looked over to Ace, his suit covered with it, levitating the bloody assault rifle.
"Mister, you're going down!" One cried out as he galloped forward, firing his gun at him.
The rest followed after his firing. Ace galloped to one and swung a hoof into his snout, he flew backward from the impact.
He fired the shotgun into one of them, each shot hitting it's mark. He shot both barrels into the other, sending him flying back.
Ace trotted back to the area where he had left Doctor Sparkle. A rope of mucus had wrapped around her throat latch and was lifting her into the air.
"Somepony help!" She managed enough breath to scream.
The pistol had fallen on the ground. Ace picked up the gun and fired at the monster pulling her up. The creature vomited body parts onto the floor, letting Twilight fall to the ground. She had fainted from the lack of air. Ace heard soldiers galloping through the hall. Ace levitated his shotgun again and trotted down the hall.
"You're dead, Sparks!" One called.
The PA system started an announcement.
"This sector is now under military control." It continued, "Reinforcements to: Doctor Sparks, Doctor Freemane. Sector E, Sector C."
A grenade sailed in the air from the door, landing directly at Doctor Sparkle's hooves. Ace Galloped over to her, levitating the ordinance and flinging it into the air, it exploding mid-flight. Shrapnel flew every direction, most hitting Ace's suit and helmet. Ace galloped over into the corridor levitating his assault rifle, pulling a secondary trigger. A rifle grenade flew into a crowd of soldiers, hooves and legs scattered in the room. Blood stained the halls. Suddenly, the floor started to shake from the multiple ordinances combusting around the perimeter. The segment of the ground Ace was standing on collapsed, the stallion falling with it.
