As David approached the entrance a man slammed his entire body into it, covering it in blood. the man screamed and kept punching the door. David took in a deep breathe and readied his gun. He then unlocked the door and jumped back. The man came barrelling through the door and landed on the ground. David used this opportunity to steady his aim. The man attempted to get up but it was too late. David pulled the trigger and the man's head exploded like it was filled with petrol. The mans blood and brains was splattered onto the floor and David's shoes and jeans. David sighed. He snuck out the door and into the hallway. He then ran down the hallway in haste and turned left. As he saw an emergency escape, multiple cries of insanity and bloodlust could be heard from behind. Without any hesitation, David ran through the emergency exit.
