Adrian felt a twang of pain in his groin, like someone had put a round in it while he was under anethsia.
Rico...
He felt his eyes tear up, and yelled in anger and pain. The vibro-blade in his hand started shaking viscously, and he tore it out of the poor bastard he had been eviscerating, and stumbled around a bit.
Seeing a moving, breathing Omega, he rushed him, screaming in rage. The bastard had time to nick his shoulder with a knife, which put a small wound in his flesh, but Adrian quickly had his revenge in the form of knocking the smaller marine to the ground, smashing his knee into his chest, and stabbing him repeatedly.
After several seconds of slasher movie-esque screams and bloodsprays, Adrian's now grotesque armor stood amidst the numerous corpses and gibs. However, there were still two more. Fian and another armor were engaged in combat with the several remaining Alpha armors, who were losing badly. Adrian, long past the point where the whole bit about "friendly fire" could have mattered to his broken mind, he moved quickly to the Aether Cannon.
With speed and grace, he moved the barrel parrellel to the ground, grinning the whole time. The medic positioned his hand over the firing key.
He switched his comm to external speakers. "Hey, Fian! Your team fights dirty!"
With that, he brought up his fist, and smashed it down hard enough to crush the control panel. Luckily, the command was still transmitted. The cavern glowed blue, and an instant later, the final aether beam of the day was fired.
