Left 4 Dead: Gemini Strain.

Chapter V: Orphanage isn't the best place to go – Robert

Robert was running, faster than he could have ever believed he could.
Fear caused this, but this wasn't like being afraid of the dark, this was the fear of death.
Robert kicked opened the wooden door leading into a rundown orphanage.
He quickly turned around and closed the door, pushing a nearby dresser in front of it.
Robert took several very deep breaths, he lean on the wall, looking into the main room, nothing.
Robert looked at his hands, they were shaking, and he didn't want to think about that poor girl. Rosalina was a girl, younger then himself, she had stunning blue eyes and shoulder long black hair, she couldn't have been more then fifteen.
Robert cursed out loud, "Why did you have to have that fucking phone....." Robert fell to his knees, thinking about Rosalina and how that zombie jumped from the roof top and landed on her, it ripped and slashed at her, ".....Rosalina" Robert said in a whisper, "Rest in peace...".
Robert quickly stood back up as he heard a noise of glass breaking, "....come on" he shook his head, he was so tired.
Robert aimed his Colt and slowly walked into the darkness, his left hand gripping a glow stick he had found.
"Fuck" Robert mouthed to himself, he heard the already too-familiar moans of the undead.
He pulled out the glow stick, cracked it and tossed it into hallway as he aimed his Colt.
Robert's trigger finger couldn't move, he was frozen from the sight before him.
Zombified kids, babies and teens were all moving towards him, he thought he had seen hell in these last days but nothing made him ready for this.
Robert looked down the hallway, a window, he reached into his back pocket and pulled out a flare, "Hope this works..."
