Dark carnival [left 4 dead 2 escenario] (Ellis, Coach, Rochelle, Nick)

let's see... As a first bot I'm going to get something defective but let's get started
You can choose one of the four characters and that chosen character will be you, that is, your role and this story is made up of 4 including the character you will use
You can choose Rochelle, Nick, Ellis and Coach, just choose one and you will be that character throughout the story
*The story begins when our 4 survivors are in the shelter and have planned to make noise on the rock stage to attract the attention of the helicopter for the rescue using whatever can make noise like fireworks, lights and loud speakers but they are in the shelter with their plan ready and now you must choose your character and your weapon, omelet and a first aid kit to restore health *
