I sat up slowly, in a daze, as the sirens wailed and the lights flashed around me. I could hear the automated message, but couldn't make out what it said. My heart was racing as a million scenarios flooded my brain at once, each more terrifying than the last.

I stood up, feeling unsteady as I walked to my desk looking for something I could use to defend myself should the worst occur. I heard a noise behind me, and a large shape rushed towards me, horrific noises bellowing from its maw. I reached behind me and grabbed my 3-hole punch, swinging it at the head of the monster with all my strength.

I connected with a resounding thud and the creature went down hard. Feeling strangely elated, yet ill, I looked out the window and saw more flashing lights.

I sat up slowly, in a daze, as the sirens wailed and the lights flashed around me. I could hear the automated message, but couldn't make out what it said. My heart was racing as a million scenarios flooded my brain at once, each more terrifying than the last.

I stood up and looked around the room, trying to figure out what was going on. There, on the floor between me and the door was an armed security guard lying in a puddle of blood, his head bashed in by something. His gun was in his hand, and I armed myself with the gun and all his ammo, and headed for the hallway, hoping to escape the building and the monsters within.

I heard noises in another office and saw two monsters that seemed to be communicating to each other. They turned towards me as I tried to walk past, and they moved towards me, one of them raising an arm above their head. I felt sick as I fired the gun and one of them collapsed to the floor.

The other monster shrieked as it turned towards its dead companion. I fired again and that freak died too.

I headed for escape again and found my exit cut off by more of the monsters. I fired, over and over again, reloading as needed. Each shot brought down more of those monsters.

Some of the beasts I killed had been attacking me, while others seemed to be trying to escape the building. I saw the dead bodies of my coworkers everywhere.

Eventually, I made it to the exit and saw the swat team pointing their guns at me and yelling at me. I dropped my gun and put my arms up.

"I think I got them all...every last one." I couldn't help but feel proud of myself that all those years playing video games had obviously paid off.

"You are under arrest, anything you say may be used against you. You have the right to an attorney. If you can't afford one, one will be appointed to you." One of the officers secured my arms behind my back and patted me down as he read me my rights.

"Why am I being arrested? Did anyone else get out alive, or did the monsters kill them all?"

"Yes, 2 of your coworkers managed to escape to tell us how you shot everyone inside"
