Left 4 Dead: Gemini Strain.

Chapter II: Surplus is a Plus with Me – Robert

Robert looked around the corner; the main street was mostly empty, a few zombies slowly moving around aimlessly. He continued to look around, grabbing at his left arm, he had been attacked by a group of these undead, he had used a first aid kit he had found on a dead corpse, along with a half empty six shooter.
"....Isn't there anybody else alive?" he said to himself out loud, trying to survive within this city was becoming more troublesome as the days had passed since him and his friends had traveled to the city on a road trip, "....Guess not".
Robert looked the street over again, a smile grew across his blood covered face.
Down the street, lights flicked near a store, the smile became a smirk as Robert read the sign aloud to himself, "Guns and Ammo Surplus!"
If there was a heaven within hell, then this was it. Robert thought as he reached into his jean pocket, pulling out a Colt M1911A1, he loosely held the six-shooter in his left hand.
Robert slowly made his way onto the street, his smirk soon faded as he saw that a horde of zombies started to rush a pack of wild dogs.
"Fuck...."

Robert quickly started to run down the street, he aimed his Colt and fired at the closest zombie, he tried to remember his younger days of watching movies and playing games, aim for the head. Robert fired again and again, he tried not to think about his lost friends, his mind questioned, what if these zombies, the scarred ones with pieces of their face missing, if they could be his friends or not.
"nah...."

Robert threw his now empty colt at a zombie, causing it to fall backwards, he was running full speed now, he had to make it into the store and hopefully hold out.
Robert smacked into the door of the store, "DAMMIT!" it was locked.
Robert turned around, sweat was dropping off of his face, a group of zombie moving closer and closer to him, fear was running through his veins like blood. Robert looked around, nothing would help, he wasn't going to just stand there and die, he rushed into the group of zombies, tackling them down onto the ground.
Robert got up and punched the closet zombie with everything he could, he quickly jumped up and ran towards the store window, "AH!" he yelled out as he jumped through the window.
Robert lay inside of the store, blood poured from his arms and back, "May...maybe not the best idea...." Robert stood up and looked out the broken window, the zombies had already started to get back up, "Hmm...." Robert jumped behind the counter and looked over the guns.
The zombies crawled through the window, Robert popped up from behind the counter, holding a M16 assault rifle, Robert smirked and fired.
