The zombies were closing in as Isabella turned around, firing her last clip into the faster ones that were the closest. 

"Shit!" She cursed, running around the large machinery in the room while spying a door she hadn't gone through yet.

Suddenly, a few lights in the room blinked on as an automated voice could be heard.

"Power restored. Artificial gravity and life support online in... Receiving Bay, Tunnel Six, Tunnel Eleven, Laboratories, Bio Dome."

The power's on! Isabella thought excitedly, knowing exactly what that meant. They're here-

A stray zombie interrupted her thoughts as it swung at her, missing by only inches as she dodged, countering by stabbing it in the neck. That was too close... I need to get the hell out of here and find them...

She ran up to the only door in sight, noticing the lights on it were red as she pressed button after button on the control panel trying to get it to open.

"Fuck you!" She screamed in frustration, hearing the moans of the undead getting closer. "Why won't you open?!" Just then she remembered what Gersch had given her as she reached into her back pocket, taking out the unfamiliar device. 

Well, it's worth a try...

Flipping open the leather cover, she held it near the door while pressing one of the only buttons and hoping for the best. A strange sound was heard before the lights on the door flashed green and a new path was available.

"YES!" Isabella rejoiced, kicking a zombie that had gotten too close back as she rushed forward down a set of metal stairs. A few moments after entering the new room, she noticed something was wrong.

"W-what the... I- I can't breathe..." She choked, grabbing the mask around her neck and pulling it over her face while taking a deep breath. Coughing a few times as oxygen returned to her lungs, she took in her surroundings, noticing the giant pyramid in the room first. 

What the f-

"Congratulations freakbags!" A familiar voice shouted through her headset before continuing, "You've found the ass-kicking line!"

Isabella's heart skipped a beat as she realized exactly who's voice that was...

"Dempsey...?"

The others had made it all the way outside again as Brianna and the doctor ran into the receiving bay, trying their best to get the computers working.

"How can you not recognize me?!" Richtofen protested, slamming a fist down against the control panel in anger. "It's ME!"

"Access denied." The automated voice stated as the German shouted a slew of incoherent curse words.

"I thought you said this would work!" Brianna commented, placing her hands on her hips while impatiently tapping her foot, hearing gunfire from outside as Tank, Nikolai and Takeo were cleaning up the remaining zombies that had followed them through the tunnels.

"It vill work!" Richtofen countered, getting more and more irritated by the minute as he tried yet another password. 

"Dammit, I hate doing zhis! Vhere's Groph vhen you need him?"

Outside the main room, Tank blasted a zombie in the face with his M16 laughing as he lined up another head shot. "Congratulations freakbags! You've found the ass-kicking line!"

A small voice echoed in everyone's head sets, making the Marine jump and miss completely.

"Dempsey...?"

"Izzy?!" Tank questioned excitedly, forgetting about the target in front of him. "Where the hell are ya?"

Nikolai blasted the last zombie in the face as they all listened to her muffled response.

"I- I don't know... I'm in a room with a giant pyramid or something... Shit! What the- Ahhhhh!"

"Isabella!" Brianna shouted into her head set as a large crash could be heard as well as the sounds of someone struggling.

"Let me go asshole!" She shouted before everything went quiet.

"Izz! Answer me!" Dempsey demanded, hearing only silence once again. "SHIT! Nikolai, Taks... I'm going after her... Keep an eye on her sister, will ya?"

"Da, da..." Nikolai answered, waving him off while reloading his shotgun, "Go get your woman lover boy-"

"What the fuck!" Brianna shouted, not wanting to be left out. "I'm going too!"

"NO, you're not. You'll only slow me down. Now STAY HERE!" He ordered while sprinting towards the tunnels, feeling slightly guilty after yelling at the girl who was only concerned for her sisters safety. "I promise I'll bring her back..." He added before running through the doorway. "Besides, you know she would want you to stay safe, am I right?"

"Yeah..." Brianna answered defeated, knowing she probably would just get in the way. "Just please hurry..."

"Ugh... W-what the hell happened...?" Isabella mumbled, rubbing her head as she sat up while noticing the pyramid was no longer in sight. This time she was in a completely different room. One she had never seen before. 

This must be the Bio Dome...

"Izzy! Where are ya?!"

"Tank! I don't know what happened! I was in the room with the pyramid, then someone grabbed me and fuckin' headbutted me... and now I'm here? This is so ridiculous..."

"Where is here Isabella?" The Marine pressed while walking past said pyramid. "Be more specific!"

"Oh yeah, sorry... I think I'm in the Bio Dome... Just keep going up the steps and you should find me!"

"Alright, I'm on my way... Just stay put!"

"Watch out for that prick in the space suit!" She added quickly, not wanting him to share the same fate of a very painful headache. "He's probably still lurking around somewhere..."

"Roger that."

Isabella sighed, taking time to observe her surroundings while she was waiting. Remembering what the automated voice had said about life support being on, she removed her helmet cautiously, taking in a small breath to test the air.

Good ol' oxygen... She smiled, thinking about how much she had taken it for granted back on Earth. I can't believe we're all actually in space... And on the moon no less! What does this have to do with the zombies? Or ANYTHING for that matter? I'm sure one person knows what's going on here... Isabella thought, frowning while imagining a certain green eyed doctor...

Thinking about all of it was making her head spin, so she distracted herself as best she could by checking out the scenery. Though there really wasn't too much to see. Why it was called the Bio Dome was fairly obvious, as the plants and general outside like appearance gave it away. It was however, much creepier than any normal garden. A few brightly illuminated pads were scattered on the ground as her curiosity got the best of her, Isabella found herself walking towards one, wondering exactly what it did.

She stepped onto the yellow square in front of her, never expecting what happened next. One second she was on the ground, the next she was thirty feet up in the air staring down at the tops of the trees and everything else in the room that now, seemed VERY far away.

"Holy shit!" She screamed, falling slowly back towards the dome's dirt floor, closing her eyes and bracing herself for impact...

Suddenly she felt someone catch her as she blinked a few times, looking up and seeing her own reflection in her savior's space helmet. Panicking for a moment, she thought it was whoever had assaulted her earlier as she reached up with shaky hands before removing their mask...

"Dempsey!" Isabella rejoiced, throwing her arms around him as he hugged her back. Both of them enjoying the silence and tranquility of moments like these, which didn't happen very often. Tank pulled away, both of their faces only inches apart as he gazed into her green eyes, feeling at ease now that he had her back in his arms.

Isabella felt it too. Her heart began to beat faster as she thought of everything they had been through together...

No matter what had happened to them, he was always there for her... Always making her feel completely safe. She smiled, kissing him on the cheek as she felt her face heat up before the marine moved a hand to the back of her head, relocating her lips so they were pressed against his. And for a brief moment, everything felt right...

Isabella was the first the break their heated kiss as she knew they had other matters to attend to...

"What happened back in the jungle?" Tank questioned while setting her down, eager to hear her reasons for sneaking off yet again. "I know you think you can handle this on your own Izz-"

"Dempsey..." She interrupted, staring into blue eyes before looking at the ground, feeling guilty about leaving the people she cared about in the dark once again. 

"I was wrong to just run off without telling you guys anything in Shangri-La... And I'm sorry... I know I can't do this alone. I'm going to need everyone's help... But," She continued, finally looking up at the Marine who still seemed unsure.

"I think I've figured out something that can help us..."

Isabella reached into her pocket, pulling out her journal before flipping to a few pages in the back.

"Here..." She continued, handing the small book to Dempsey as she watched him look at it curiously.

"What the..."

The image in front of his eyes was a cartoon drawing of the jungle they'd just come from, the scene depicting the temples being sucked into some sort of black hole...

Is that what happened to bring us here? He wondered, temporarily mind blown as Isabella reached up to turn the page.

Pictures of space and moon bases caught the Marine's attention next, filling his mind with so many questions as he struggled to organize them all. 

I guess she wasn't lying when she said this was a game... He realized, looking at the one side of the comic which was filled with various items you could apparently send away for. I might have to try that...

"I don't know why Sam gave me this information..." Isabella spoke up, getting his attention as he looked past the comic book pages towards her. 

"But I'm going to use it against her..."
