Mark shuffles down the dark hallway. His team members close behind him, each mindful of the soft sound of their steps on the concrete floor. A soft clicking sound is heard from around the corner and everyone freezes. Thats the sound of one of the zombie..things. To put it simply: when they click, everyone needs to freeze and shut up. Mark grabs his knife from his side and makes quick work of it, stabbing it through the head. He has guns, but those are saved for when all hell breaks loose.
