The Marines in the vehicle bay were expecting a confrontation. They, along with the two Goliaths that stood behind them, were on high alert, prepared to deal with anything. They wouldn't have to wait much longer, as soon enough, the adjutant piped up again, speaking to Carver. He listened intently, tightening his grip on his rifle as he heard that unknown life forms were entering the ship. As the adjutant finished speaking, the comms had lit up with the panicked voices of the crew, talking about creatures that were clawing through the walls of the ship. He could hear screams and gunshots throughout the ship, while the adjutant told him that some of the crew had gone into a state of hysteria. Everyone in the vehicle bay was on edge, looking for any signs of the unknown attackers.
Soon enough, their attention was drawn to the walls of the vehicle bay, as large holes were torn out of the walls, and four-legged creatures began to crawl into the room. While the sight of these monstrous beings might terrify a normal person, Carver only felt his resolve strengthen. He had faced down ultralisks and lived, and he would be damned if some four-legged zombie cockroaches would bring him down. Putting his visor down, he aimed his gauss rifle at the nearest creature, the men around him doing the same. They stood with their backs against the door, forming a semicircle as the creatures closed in on them.
"OPEN FIRE!" With that command, the Marines began to fire on the creatures, unleashing a hail of automatic gauss fire on every creature they could see. At the same time, the two Goliaths opened up, their side-mounted autocannons unleashing concentrated fire on the areas with the largest concentration of the creatures. The UED forces stood their ground, determined to utterly destroy the enemy that had made the mistake of attacking them.
Meanwhile on the bridge, Specialist Lee looked over a terminal, watching as the dot that represented the unknown energy source drew closer to the crashed ship. While they were expecting an attack, they didn't think that their enemy would be able to shred through metal walls like paper. As the adjutant began to speak again, he could hear the sounds of the attackers drawing closer and closer to the bridge. The bridge crew had barricaded the door with leftover debris from the crash, but it wouldn't hold for long. There were four other men on the bridge besides Lee, who were currently aiming their carbines at the door, waiting for something to break through it. A futile gesture, it seemed, given the reports from the other crew members that guns seemed to do nothing against them.
Frowning, he looked back to the terminal as the adjutant chimed in on the unknown signature. The fact that energy was building up around it made him suspect it was a ship of some sort. Likely powering up weapons. It was cloaked, but the energy it was emitting was more than enough to tell the guns where to aim. Looking over to the adjutant, he spoke. "Computer, I want all guns to fire on that signature. Shoot it down."
As the adjutant acknowledged his order, he heard a loud banging noise, and the door to the bridge shuddered as something began to tear through it. Soon, the door was ripped apart, and the creatures outside became visible. As they began to tear through the barricade, the bridge crew began to fire their carbines. With the creatures so close, Lee was able to sense the energy they were radiating better. To his surprise, it felt somewhat similar to psionics. A plan began to form in his head. Let's see how they like this...
As the creatures got closer to breaking through the barricade, Lee began to channel his psionic energy. While all Ghosts could use their psionic powers for lower level abilities, only a select few received enough training to pull off more advanced techniques, and Lee was one of them. Shooting his hands out, he sent a wave of psionic energy towards the nearest creature. It was a move known as a "psionic lash", which involved unleashing a large amount of psionic energy on one target, usually killing said target. Usually.
Outside the ship, the four topside gauss machine guns turned to face the source of the energy signature. Aiming at where the ship's sensors thought it was, they began firing in its direction. The four guns unleashed a stream of gauss fire, lighting up the night. Anyone in the area would be able to see and hear the fire coming off the ship.
