Left 4 Dead: Gemini Strain.

Chapter XX: The Tower Babel – Adam

"Latvia!" I screamed aloud as I tried my best to peer through the still dense amount of dust and debris. The dim light that came from a few light bulbs down towards that bottom were destroyed leaving little if no light to grace the depths.
"Latvia!" I yelled again into the blackness, fumbling to grab my SIG 226 and shine it into the darkness. "Please answer me!"
My breathing was becoming more labored every second.
Her voice was a beacon that gave me hope. Her voice was what kept me going. Her voice was what made my heart leap. Her voice was an indication of her life. "Adam..."
"Are you okay?" I yelled to her a tad bit frantically, finding my gun and shining its light downward. She looked frazzled as she looked above her collapsed position at me with wild eyes. Her descent into the abyss had been a short one, though uncomfortable. I was in the back of my head hoping that she would not look down and see what had broke her fall. Corpses.
"Yeah..." She replied weakly to me. She glanced down to my chagrin and froze for a moment. That brief pause brought no change to hear face as she looked up at me, a question on her lips. "Are you okay, Adam?"
No. I have to hurry or else I won't make it in time.
"I'm fine." I wheezed at her. I swept my flashlight around her to look for something. Without seeing it I decided to just ask. "Lat, do you know where your shotgun is?"
She shook her head no at me. Odds are it was lost among the debris. I told her to hold on and began to dig through my backpack. I found ammo for the assault rifle I had and replaced the magazine in it.
"Heads up!" I said to her as I carefully dropped the rifle down to her. She looked grateful but her voice was still hesitant.
"Adam, you have to stop that bell!" she said to me with eyes wide open.
"I know..." I replied with a wheeze coming from my throat. I looked up toward the steps with a heart now filled with dread.
Dammit. I want to give up.
"Adam, go now! I'm going to make my way back to the station and help the others!" she told me, holding the weapon surely in her grip.
I did not respond to her and instead brought my hands to my neck as I pulled out my necklace from underneath my shirt. It was a chain necklace with an old key wrapped in aged twine, a simple trinket but it meant a lot to me. "Catch!" I told her as I dropped the necklace into her open palm. She looked at quizzically at first and then looked at me with a weak smile.
"When this is all over I want you to hand that back to me, okay? It's a promise that we will make it out together, alright?" I asked her. She smiled again at me and with a nod and a deft right hand she attached it to her neck. She turned toward the busted door and scaled over the debris and corpses to it.
"Latvia!" I called to her one more time, causing her to turn suddenly to my visage above. "Be safe."
