Let me explain a few things.

Thanks to everyone who has read and reviewed this story so far! I appreciate constructive criticism and am humbled by your praise! : ) Thanks again!

From here- Since everyone has probably played Blue Shift, I'm not going to waste your time re-writing something you've already seen. Therefore, this is going to be Jenna's POV. I have doctored one scene where she meets up with Barney (which, obviously, doesn't REALLY happen in the game) and I have also included…..drum roll, please, ADRIAN SHEPHERD! Instead of Adrian Shepherd being taken by the G-man after his battle with the Gene Worm, I am writing this as if he continued on after the Gene Worm and ran into our favorite security guard!

Jenna came to, and remembered what had happened. She rubbed her eyes, which were throbbing in her skull from a migraine. She was somewhere in sector D, lying in an administrative office.

She decided to go back to look for any survivors. She walked to the nearby tram platform, but the rail was snapped down the line, spewing sparks of electricity. She would have to go a few levels up to Breen's office, where, as she remembered, there was a mysterious tram that she had never ridden before. Hopefully it would take her somewhere else.

She went to the nearest elevator, which had toppled to the bottom of the shaft. She looked up, and realized that she had to take the ladder to the top. She began to climb, trying not to look down. She finally reached the upper administration offices, where Dr. Breen had his office. She went down the familiar corridor to his office. She saw that the door had been broken off the track. The office was abandoned.

"COWARD!" Jenna yelled in her own head, "He probably fled at the first notion of disaster!"

Suddenly, a strange noise came from behind her. She whirled around, seeing a strange crab-like alien flying towards her. Jenna dove out of the way, pulling out her gun. She shot the alien, which flopped over, dead.

She walked down the corridor, towards the upper level tram platform. When she had almost reached the door, she heard gunshots. She ran through the door, and saw a security guard taking out two of those brown aliens.

"Dr. Brandenburgh!" The guard yelled, "What are these things?" Two more teleported in, and Jenna assisted the guard in dispatching them.

When the aliens were done dropping by, the guard turned to Jenna again.

"Seriously!" he said, "What are these things?"

"I don't know," she said, "I think what happened in sector C must have created some dimensional tear and attracted the attention of….other beings."

"well, whatever they are, they have been crawling around the entire facility for the past three hours!" the guard said, sounding very panicked.

"Three hours?" Jenna said. She had been unconscious for thatlong? She desperately needed to see if Kleiner, or Barney, or Gordon, or ANYONE was still alive.

"So, where does this tram go, anyways?" Jenna asked, motioning to the stationary tram sitting at the platform.

"The….uhhh… I can't really say," the guard said.

"Seriously?" Jenna said, "I think that security has pretty much gone out of the window! Look, I need to search for survivors, but the tram below is broken, so where does this tram go?"

"The upper sector E labs, the biodome complex," the guard said.

"What's there?" Jenna asked.

"I honestly do not know," the guard responded, looking legitimately confused, "I'm just supposed to make sure that only level 6 clearance and above personnel board the tram."

"Alright, well, once I get to the upper sector C levels, there has to be a way to get to the lower sector E levels and hopefully on to a working tram to the rest of the facility… can you let me through?" Jenna asked.

The guard nodded. Jenna boarded the tram, and the guard punched in a code causing it to start. After a relatively short trip, it arrived at a platform she never had seen before. She went through the main doors, and saw that the main entrance, besides the fact that it was still under construction, looked a little bit like the lower sector E entrance.

"Now," Jenna thought, "where is an elevator?" She looked at a nearby map. This complex consisted of several levels with large observation areas in the center. It looked like there were two elevators that went to the lower sector E labs- one across the level she was on now, past an observation area, and another elevator up on the next level, and over the other way.

She went across the entrance, to a door marked "observation area entrance." She went through the door, around a hall, and came across something that shocked even her (which was rare considering the day's events).

The observation area was actually a replica of Xen, complete with the rocky terrain and plant life. Through the glass, she could see everything, including living aliens running around the large area. There were alien-dog-things running around, frolicking around needle plants. There were also three more of those crab things, but they were sitting peacefully on some of those green flower plants she saw in the Xen cave.

"Those sons of bitches!" she cursed to herself, "They KNEW about these aliens? They KNEW that Xen had hostile aliens on it, besides the plants! They used me to protect the exploration team in case those three armed freaks came or in case those huge gray alien grunts attacked!"

She felt angry and annoyed. She also felt betrayed by Dr. Kleiner, but she figured that we was not allowed to tell her the truth. As she walked down the hall, passing the observation area, a strange alien teleported in behind her. It was about 7 feet tall and had one large eye. It had what looked like a large cockroach on its arm, only the roach thing spat electricity at Jenna.

Jenna ran down the hall, disappearing behind the corner. She peeked out, and put a bullet in between its eye. It fell on its knees and flopped onto the floor. However, the roach thing was still alive, and crawled around before jumping towards her.

"AAACK!" Jenna screamed, she caught the roach, which gave her a hard shock. She threw it against a well, and it fell onto the floor and died.

Jenna finally reached the other side of the area, and went through the door. Her heart sank when she saw that the elevator was out of service. She had to go to the small lift in the middle of the laboratory, go up one level, and take an elevator on the second level down to the lower labs. She took the lift up and searched for the next elevator. When she got to it, she was relieved to see that it seemed to be working. She pressed the "down" button, and it came to her. She stepped on and pressed the lowest level button and the elevator lurched to life.

When it came to rest, she got off and realized that she was about two floors below her old sector E office. The security guard guarding the secret elevator was dead, Jenna sighed and stepped over him, continuing on. She decided that she would make a quick pit-stop to her office and grab the tao cannon stored in her old office. She walked on, and saw the dead body of a marine, still smoldering from what was probably an electricity blast. She frowned, turned the body over and read his dog tags.

Jenna gasped. Her sector-the HECU- was dispatched for this job. She looked above his body, seeing that his shotgun was laying there. Grateful, Jenna grabbed it, cocked it and prepared for a match-up with whatever killed her comrade.

When she rounded the corner, her instincts were right. A brown alien was waiting, but before he could shoot his electricity at her, she blasted it with both barrels of the shotgun, sending it flying backwards. She went up two nearby flights of stairs, finally arriving at the level where she used to do weapons research. The lobby had three dead marines, and Jenna grabbed some more shotgun shells as well as a sub-machine gun. She frowned when she realized they were more HECU marines. She walked into her office, opened the safe and grabbed the tao cannon. As soon as she grabbed it, another brown alien appeared. She made quick work of it, blasting it with the powerful weapon.

Jenna sprinted out of her office to the tram platform, only to be annoyed to see the rail was, again, snapped in a small segment right in front of it. She knew that she would have to make her way on foot to the next nearest platform, and hope that the next section was still unscathed. She climbed the service ladder down, and made her way through the maintenance passage. It seemed to go on forever, and she had to battle alien crabs and brown aliens randomly teleporting in.

She finally arrived in the far end of sector F- the lambda labs. It was a far reaching part of the labs that she had never seen before. At the tram station, however, there was a radio communication station. She tried to radio out for help, but couldn't get anything. She radioed within the facility, which was fortunately still working. She radioed around, hoping to find Dr. Kleiner.

"Dr. Kleiner? Doc? Doctor Kleiner? Are you there" She said, changing the frequency every so often and repeating herself. Finally, there came another voice,

"Jenna? Jenna is that you?" It was Eli Vance.

"Dr. Vance! Yes, it's me! Are you alright?" Jenna said.

"Yes, I'm alright. Alyx and I found Dr. Kleiner up and are all hiding in the sector B maintenance area. We can't talk long, though. The military will find us with this frequency"

"Alright, just stay there and I'll come and get you guys" Jenna said, "I'm kind of far off, and the trams are mostly down, so it might not be for quite awhile, though. Find somewhere safe to hide, preferably somewhere you can hide for a few hours."

"Ok, will do. Good luck and we'll see you in a few" said Eli.

Jenna but the radio back down. She looked at a map on the wall. She could take the sector F tram to the main transit station. From there she had easy access to sector B, if the trams were still running in the central station. If not, she would have to make her way on foot, and probably through the ventilation systems. She boarded the tram that was sitting there waiting. She pushed the button for the main transit station. Surprisingly, the sector F lambda rail was relatively unscathed. She reached the central transit station, which was a mess of HECU soldiers and alien creatures. Jenna noticed that the rails were down, and decided to skip the large battle in the station and, instead, go down to the maintenance canal to find another route to sector B.

She made her way through the maintenance canal until she reached a dead end. Frustrated, she looked at the map on the wall, but it wasn't a map. It was actually blueprints for the maintenance personnel. They only showed the ventilation system that winded around the main transit area, down wards (where she was now) and over to the very lower levels of sector C. Jenna knew that from there she would be able to make an easy path to her colleagues in hiding. She looked down at the vent on the floor.

"Well, if Gordon and Barney can do it, then I can, too," Jenna thought to herself.

She pulled her mask out of her storage belt and put it on. She turned on the night vision goggles, pried off the vent and began her journey. She crouch-walked through the vent system, which was annoyingly infested with the alien head huggers. She took them out slowly, and gradually made her way deeper and deeper into the base. As she journeyed on, she could hear battles all around her. She came around a corner, hearing people fighting aliens below her. Unfortunately, a head hugger jumped out from around the corner, causing Jenna to instinctually shoot it with her gun. The battle below her became quiet, and she could hear voices below her.

"Did you hear that?" A male voice said.

"The vent" whispered a female voice.

Suddenly, the vent began to get riddled with bullets. Jenna tried to climb away from the gunfire, but her climbing over the weakened vent caused it to collapse underneath her, and she plummeted to the ground. She was immediately surrounded by 4 people in black outfits that covered their entire bodies, as well as black masks covering their entire heads- Black Ops. Jenna had recognized them from her own military training. She herself was being scouted to become a black Op sniper (at least that's what her squad commander said), but she was reassigned to Black Mesa instead when she was injured.

They reloaded their guns and were about to shoot her to kingdom come when suddenly a troop of those large alien grunts with the metal plates on them teleported it and began shooting strange bee-like creatures at everything in sight. The black ops dispersed, and Jenna quickly sprang up from the floor, climbed onto different crates, hopping from one crate to another until she could reach the vent. She hoisted herself back into the vent and pulled out her shotgun.

The battle raged on below her until there was one alien grunt and one male assassin left. The assassin tried running from the alien, but the alien picked up the man and threw him through some wooden storage crates, killing him. Jenna noticed a crossbow was in the crate, along with probably 6 clips of arrows. Jenna cocked her shotgun and repositioned herself in the vent, and with one hand she lowered herself down from the vent while shooting the grunt with the shotgun in her other hand.

The alien went down hard, so Jenna dropped down, grabbed the crossbow and arrows and loaded a clip of 5 into the gun. She aimed at a wooden crate, and shot the gun to get a feel for it. The crossbow was very powerful, splintering the crate into a million pieces with just one shot. Impressed, Jenna strapped it to another strap on her back and hoisted herself back into the vent.

"OK," she thought, "this crossbow should make easy work of those black op freaks!"

Jenna continued through the vent, turning left, right, left, left, and right again as the vent did (luckily, it didn't splinter off into different pathways, so it was an easy journey). She finally saw a light on the end of the vent, and realized that she was on the ground level of the sector C lower maintenance area.

Jenna reached the end and crawled out of the vent, onto the floor of the empty hallway. She took off her mask and began to listen intently. She could hear voices in the distance. They were muffled at first, so she sprinted towards them. She rounded a corner, hearing a familiar voice.

"I don't know how to get to the surface from here, PAL! I'm just as lost as you are!"

It was Barney's voice, sounding slightly shaky.

She continued down the hall, stopping just behind the last corner. She peeked around the corner and saw Barney, with blood on his cheek, laying on the floor while an HECU marine pointed a shotgun at him.

Jenna thought fast. She quickly pulled out the crossbow, looked through the scope, aiming at the gun, and shot it straight out of the marine's hand with much force. The gun landed with a loud *clunk* on the ground about 2 feet away from the marine.

"DON'T MOVE, or the next one will go through your facemask into your skull!" Jenna yelled when she saw the marine attempt to bend down and get his gun back.

"Jenna?" Barney yelled, seeing a figure that gave him hope.

Jenna ignored him for the moment, focusing only on the standoff with the masked marine.

The marine straightened up, looking at Jenna.

"Brandenburgh?" Came a familiar voice. The marine's voice was slightly distorted by his mask, but it was still recognizable… could it be….?

The marine took off his mask. He had brown hair, beautiful blue eyes, a prominent pointed nose and a squared chin. His very handsome features were too familiar to Jenna. It was none other than….

"ADRIAN!" Jenna gasped, "ADRIAN SHEPHERD?" Jenna dropped her crossbow and ran towards the marine. She jumped into the marine's arms. He smiled wide and began to laugh.

"I can't believe I found you! I knew you were stationed at this hellhole, but GOOD GOD! WHAT HAPPENED?" Adrian Shepherd said, hugging her tight.

"Oh god, Adrian!" Jenna said, smiling at him, "I never thought I would see you here! I don't know what's going on. There was a huge accident, and I think it attracted the attention of these…alien things."

"Jenna?" came Barney's exasperated voice as he slowly got up from the floor. He could feel the anger rising up to his face, "What the hell? You know this guy?"

Adrian looked at the security guard and then back to Jenna, "you didn't tell your little buddy here about me?I'm slightly offended."

Jenna laughed, "Yea, sorry about that. If it were at all possible, I'm sure your ego would be much bruised right now" she said, giving Adrian a friendly punch on the arm.

Adrian suddenly got very serious, "Alright, look, we need to get to the surface. When we were ordered to pull out, government black ops were sent to stop the infestation, as well as silence anyone left down here. They even had a nuke! I shut it off, but I don't think that they are looking to preserve this place. If I know black ops, then I know that if that bomb doesn't go off, they'll probably just bomb this place from the air. We don't have much time-only about as long as it will take them to realize the bomb was deactivated and to call in aerial reinforcements. We need to go."

"You're right," Jenna agreed, "but I want to gather up some survivors- Dr. Kleiner, Eli Vance and Alyx, who are in hiding. They're not too far from here, so we can gather them up as we get to the surface. Can you help us, Barney?"

"I'm not going with you," Barney said bitterly, refusing to look at Jenna, "You are the cause of this whole mess!"

"What?" Jenna gasped at Barney, "Are you kidding me? How could you say that?"

"You were working in the lambda labs, you collected the crystal, you unleashed these alien freaks!" Barney said, "you knew what you were doing, and all of the innocent bystanders are being slaughtered by aliens because you were playing God and tampering with alien life!"

"Barney," Jenna snapped, getting slightly annoyed, "You know that's not true!"

"You were part of that team, right? That collected the crystal from the alien planet?" Barney said, "Yea, one of the scientists told me about your guys' multiple explorations to 'Xen' to get these things. You were jumping around planets and messing with aliens!"

"Barney!" Jenna responded, "I didn't know that there were aliens on that planet. They didn't tell me anything!I was just following the orders I was given! If I knew that there were any living creatures on that planet, I never would have been part of this whole mess! You know that."

"I'm not so sure I do," Barney said, coldly.

"Adrian, can you give us a second?" Jenna asked, "Just keep a look out."

Adrian looked annoyed, but walked away to the end of the hall, keeping guard.

Jenna pulled Barney aside, out of Adrian's earshot, "What is your problem? Why are you acting so cold to me? You know I didn't do anything intentionally wrong!"

"NO I DON'T!" Barney yelled, "I know nothingabout you! I don't know anything about your past, or your time chortling around with your super-aggressive freak friend over there" he said, motioning his head towards the marine pacing the hall "I know nothing about you!"

"Is this what you're so pissed about?" Jenna asked incredulously, "You're upset about me having a past with Adrian? So what? We are friends. We were in the same UNIT! We were in the same unit for three years, after his basic training, and after that I was assigned to come here, and I never spoke to him again. So what? I didn't bore you will all my boring marine corp. stories and now all of a sudden you think I'm some rogue scientist running around pissing off alien life forms for fun?"

Adrian began to walk back "We got to get moving, I don't want to stand in one place for too long! Can you soothe the baby later?"

Barney glared at the marine, and then looked back at Jenna, "No, I don't think you're a rogue scientist," he paused before glaring at Jenna, and through gritted teeth he finally said, "I think that you are a marine grunt in a lab coat pretending to be a scientist."

Jenna's heart broke, and the expression on her face matched it. He had dug into her out of hatred. Jenna looked shocked and offended, causing Adrian to shove the butt of his shotgun into Barney's chest, knocking the security guard onto the floor. Adrian pointed the gun at Barney's chest.

"ADRIAN!" Jenna screamed, Adrian ignored her and looked at Barney.

"Listen, pal," he growled, "This is not her fault. You don't know anything about her assignments, or how much she knew. I'm not going to sit around and listen to you insult her. She is has a PhD- she is a damned fine scientist and a damned fine marine. What are you? A dropout from donut dunker university?"

Barney said nothing. He just glared at Shepherd.

"Now, here's the new order of things, you're gonna listen to us, or….not" he said, cocking the shotgun, "your choice."

"Adrian, CUT IT OUT!" Jenna yelled.

"yea, whatever, pal"Barney hissed, "Your only solution is to silence any innocent bystanders, isn't it? How many helpless scientists have you murdered today?"

"For your information" Adrian said, "I haven't touched a single one of your idiot scientist friends. That wasn't myorders. My orders are to abandon this place and get the hell out of here."

"Adrian!" Jenna finally snapped, pulling the gun out of Barney's path. She offered Barney a hand, trying to help him to his feet, but he refused it. He slowly got up, brushing off his pants.

"C'mon, Barney," Jenna pleaded, "This is ridiculous! You know me! You know I wouldn't do anything to hurt innocent people! I had no idea about any sort of hostile alien beings—I was manipulated by BREEN!"

"I'm not going with you two" Barney said, sounding very bitter, "I'll find my own way to the surface."

Jenna sighed, looking down at her feet.

She paused a moment, before leaning closer to Barney, saying very softly, "I know that you are just upset. You know that I didn't intentionally mean to be involved in something that killed my own friends. I just hope that one day you can forgive me for unintentionally taking part in this disaster, and forgive me for not being able to tell you everything. I didn'twant to keep any secrets from you, but there were certain details about my life that I was obligated not to tell anyone. I hope one day you can understand that and remember the kind of person I really am."

And with that, she pulled off the necklace from her neck, and placed it carefully on the floor in front of Barney's feet. She looked at him one more time, with small tears welling up in her eyes. She walked back to her dropped crossbow, picked it up and looked at Adrian.

"C'mon, Adrian," she said with another large sigh, "There's nothing else for us here."

As they walked away, she looked back at Barney one last time, and he just stood there with an angry, stone look on his face.

When they disappeared out of sight, Barney sighed, fighting back tears. He bit his cheeks as he bent down, picked up the necklace Jenna laid at his feet, and put it securely in his pocket.

He walked in the opposite direction. His fear and anxiety was now replaced by overwhelming feelings of regret and sadness. He had a sinking feeling that he would never see the woman he loved so much ever again.
