As TDN stood and watched the fight happening before his eyes, he could not believe the ferocity of these creatures. He saw them, how they fought to the finish, each enraged with their desire for victory, each filled with frenzy and a complete hatred of each other. They had both fallen right before his eyes, something he had not expected at all. They had fought to the finish, to the bitter end. Such rage he had never saw before. He had always had a hatred for both of these creatures, but now he could somehow feel a bit of admiration for the both of them, admiration for their determination to not stop until the other is dead. "Such determination from such mindless creatures" he thought. He let out a sigh, and thought to himself "Well since that's over, I guess I should continue on".
Then he remembered something. He looked around, especially focused at the scene of the battle, and he could see only one of the three Xenomorhps that had escaped. "That means the other two are still out there" he thought "Goddamnit! I hope nothing will happen". But his hopes were not fulfilled, for right then, he heard sounds of screaming coming from the direction a a darkened hallway. TDN ran to it, hoping that it wasn't anyone from his squad. And yet, there was something in him that wished for it to be those ignorant scientists who allowed these creatures to have their chance of escaping. He wanted them to get exactly what they deserved.
Some time past, after a long moment of running in the dark hallway, he finally arrived at a dimply lighted room, where the screams had came from. He walked slowly, trying to anticipate any traps that might come at him, so that there wouldn't be anything that would surprise him. TDN suddenly noticed he stepped on something. He shined his lights down and he could see that it was the bodies of two Marines from his squad, each of them had their brains punctured by the Xenomorph's second mouth, their blood all over the floor. TDN closed his eyes in distress. "Those scientists let these creatures escaped, and now they've taken the lives of my men" he thought. They will pay, after these creatures pay first.
Scanning the room, he was trying to find where those Xenomorphs are hiding. They couldn't have gone far, for the screams weren't that long ago. TDN followed the trail, and he saw something else. The trails seems to lead to the outside of the colony. Slowly he approached the door, trying carefully to avoid any tret by these creatures. Opening the large door to the outside of the colony, he stepped slowly, making sure each step was careful. These creatures were smart indeed, for they have even figured out how to escape the confines of the colony.
In a sudden move that surprised him, even in his alerted state, one of the Xenomorphs leapt out at him, almost pinning him into the ground if it wasn't for his last-minute reaction which allowed him to leap out of the way. He stood up, looking at the Xenomorph, an expression of, anger in it. The other Xenomorph appeared, slowly out of the shadows, the same expression of hatred in it. TDN understood now why they're so enraged. He had killed their first alpha, and they desire their revenge. Now that their second alpha had died from the battle he had just witnessed, they've become even more angrier. He stood there, looking at the both of them, waiting for their strike...
*Note: The two Xenomorphs here are Drenton and AVPFreak. I'll wait for you guys to attack first.
