Left 4 Dead: Gemini Strain.

Chapter XXI: Don't Trust a Rigged Gun – Robert

Robert pushed Lucy inside of the Police Station. He took a quick look around the main room, eight medium sized windows each side of the room, most of which had been boarded up with thin wood and some with metal pipes and a single wooden door on the left side.
A small group of survivors stood near the back of the room. "Where are the kids?" Robert asked, he was breathing heavily, he felt something cold running down his left leg, blood.
An older women stood up, "My husband went to help stop that running....told us to keep the kids back in jail cells" the older lady replied, she was scared, they all were.
Robert looked at the three, a girl older then himself, and two guys about his age, "Can you take her back there?" He asked the old lady, who replied with a small nod. Robert looked back to the three, "What weapons do we have here?" Robert looked back towards the front as shots started ringing out, "....Shit".
The blacked haired teen jumped up, "I'm Ken.....we've got a few handguns, a working mini gun we placed over there" Ken pointed towards the right wall, Robert cursed himself for not noticing it when he looked the room other, he was tired plus the blood he was losing was causing him to overlook stuff, "We also have a few automatic shotguns, rifles and a few other things back behind this door" Ken then pointed towards the door right behind the group, "Thought it would be best to protect our ammo, better than some damn kids"

Robert punched ken, knocking him over, "Fuck you!" Robert walked over him when the teen jumped up, "Who do you think you are?!" He pointed his pistol at Robert, the girl moved between them, "Please stop this Dan....we've all been through a lot this last week....let's just get passed this too"

Although living through this seemed impossible, Robert agreed with her words, "Help me up....one of you guard the way into the jail cells" Robert pushed opened the door into what was once the Chief of Police's office. It had been modified to hold all types of weapons.
Robert walked over to a table, he looked it over, all sorts of knifes and daggers.
"Hmmm..." Robert sat down his gun and picked up a dagger with a 10" blade, he took its cover and buttoned it to his belt as he walked over to the rack of automatic rifles; Robert smiled as he took an M-16 from the rack and stuck a few clips into his pants.

Robert stood next to the girl, her name was Lily, "....It sounds like a war outside" Robert said, his body was there but his mind wanted to know how was Russ doing, how far had Adam made it but those thoughts were quickly taken from him when a group of zombies busted through one of the windows, "Fire!" Dan, Ken and Lily all opened fire with their handguns as more and more zombies started to push through, doing whatever it took to get to the survivors.
Ken stopped firing and ran over to the mini gun, "Die you fucking zombies!" Ken pulled the trigger and at the base of the gun it started jerking wildly, "Wha-" Dan had moved down the few steps and into the line of wild fire, "No!" Ken yelled out, letting go of the mini gun, it still fired off, it had been rigged, Dan's body had been ripped apart from the armada of bullets that was flying across the room.
"Move!" Robert yelled out, pushing Lily down as the line of fire crossed over them, "Take over that gun Ken!" Lily yelled at the top of her lungs, "Do something!"
Ken was in a state of shock from killing his friend, "Ken!" Robert and Lily both yelled out.
Ken shook then moved forward, he grabbed the handles and did his best to point towards the undead.
Robert helped Lily up and they both started firing into the crowd, "Dammit!" Robert said as the bell rung out again, "We need to move bac-" Robert was cut off as a zombie jumped from across the room and landed on Ken, tearing him apart.
Ken yelled out for help as Robert pushed Lily backward, his eyes were filled with rage, "Mother!-" Robert swung his M-16 from around his shoulder, "Fucking!-" The Zombie looked up from Ken's dead body, blood poured from its mouth, Ken's guts hanging from its mouth, "Jumpy!-" It lowered its body closer towards the ground, "Zombie!" Robert fired as the zombie jumped towards the wall, he had missed, "Your not getting-" he cut himself off as the zombie jumped passed him and tackled Lily down.
Robert quickly turned around, spraying bullets as he turned, the zombie lay dead.
Robert fired into the crowd, they were starting to get passed the walls they had made. "Come on Lily...." Robert looked Lily over, blood was pouring from bullet wounds to her right arm, chest and forehead, Robert couldn't believe it, he had killed her, ".....No-" He threw up.
Robert slowly stood up, a zombie moaned out from behind him, he quickly turned around and hit it with the butt of his gun, causing it fall backwards, knocking down another zombie, "AHHHHH!" Robert yelled out as he fired wildly into the crowd.
Robert only started to move backwards, towards the jail cells once he heard the click of his M-16, he had emptied it out.
