The Cusp

I'm in my old high school, it's a zombie world, and there is a man at death's door locked in a room. The other people with me want to kill him before he turns, but I'm like "WTF is wrong with you people?!?!?!? I'm going in there to save him!". I go in to give what aid I can, but before I reach them an, he gets shot in the forehead and instantly turns into an unkillable mad zombie (from Z Nation). Luckily, the zombie charges the door the bullet came from, and I sneak out another door.

I run through the school which is completely empty of both humans and zombies, looking for a defensive position, and settle on the big metal doors of the locker rooms. I get in there, and a whole lot of nothing happens until I wake up.
