Left 4 Dead: Gemini Strain.

Chapter VII: Jumpy Zombie? - Robert

Robert moved quickly, grabbing the handle of the door and slammed it closed, locking it.
He took a few steps backwards, turning around to see the front door being smashed in. "Shit!" he aimed his Colt and fired at the door, moving towards the staircase, "The roof is looking like a much better..." Robert cut himself short as the zombies busted through the wooden door, he emptied his Colt into the horde, holding his ground on the staircase.
"Piece of shit gun" He yelled, throwing the gun down and grabbing the M16 that was around his shoulder, he tighten the muscles in his legs to hold his ground and fired.
Robert took a deep breath, he had killed them, he could still hear banging on the hallway door, "How in the hell I let them talk me into this trip..." Robert looked his M16 over, empty, "...I'll never know".
Robert took a few steps backwards onto the next floor when he heard a deep growling noise from behind. Robert turned around, a zombie was kneeling by a broken window, blood dripping from its mouth, horror and anger overcame Robert as he saw the dislocated head of Rosalina, lying next to the zombie's hand, her hair wrapped around its hand.
They looked into one another's eyes for what seem liked hours, "Your that fucking jumpy zombie that killed Rosalina...." Robert started to reach for his Sniper Rifle as the zombie's growling grew deeper.
Suddenly the zombie jumped forward, tackling Robert down the staircase, "AHH!" Robert yelled out in pain as his body slammed into the hardwood floor below, he quickly rolled to his side and stood up. The zombie was now standing fully erect, it was just a little taller than Robert, it moved quickly towards him, pulling its arm back to attack.
Robert rushed forward, tightening the muscles in arms, the zombie swung at him.
Robert ducked down, dodging the punch, he quickly moved up and punched the zombie in the face with everything he could, it stumbled backwards, "Fuck you!" Robert said, he looked at his hand, it was covered in slime and blood, "Eww".
The Zombie recovered quicker then Robert could react, it moved and slashed him across the chest. Robert grabbed his chest as the zombie pinned him down again, pulling its arm back to strike again.
Robert closed his eyes, awaiting the only outcome, death.
Suddenly, shots rang out.
