Extend the Story - Add a Room

The driver eventually starts rounding everyone up to the school, telling them to leave their backpacks. "We've surrounded the school. There is no point in resisting. We destroyed any communication devices inside the school. The teachers have been rounded up in different rooms, guarded by more of us. You might be asking what we're doing, what our purpose is. Just shut the hell up, and nothing's going to happen to you. Unless we feel like it. Haha! Oh, wait, right. I forgot. Hand your phones over, or I'll shoot you."

After taking all the phones, he leads you into the school. The front door is guarded by three henchmen, wearing black ski masks and carrying guns. What is going on? Why are these guys invading a school? There's no money here, is there? What do they want?

Eventually, you and another group of students file into a classroom. A few desks are scattered around the room. "Keep quiet and stay in there, or I'll shoot!" yelled the guard at the door. He wore a bullet-proof vest with a symbol on it. A big "JS" in a golden circle. Probably stood for something. Probably, "Jerky Shitheads". Haha. No. This is no joking time. As soon as the door closes, you and about 7 other students sit alone in disbelief. You're lucky the guard is standing on the outside. Small talk starts to go around the room. Everyone is immensely scared. You immediately start to formulate plans for escape.

No one in the room has a cellphone. Looking out the door window, you can see some other thugs ransacking the school, obviously looking for something. That must be their reasoning! They must think some crazy treasure is buried here. Nah, that's stupid. Anyways, how are you going to get out. You've never been the type of person to be enclosed in a room with strangers with angry terrorists outside with guns. Then it dawns on you. Obviously the police will come and resolve all of this eventually. Yeah! You start to relax a little bit. You just have to wait it out. After a few hours, though, nothing happens, and you start to panic. Everyone is thirsty and bored to death. You need to escape. You have to escape. This will be your "big impression on everyone". But what escape options do you have?

The guard standing outside says to another guard at the next classroom down the hall that he has to go to the bathroom real quick. The other guard wears headphones, and doesn't hear the guard. Your room's guard leaves. This is your chance. Should you run outside somewhere else? There are barely any guards in this hallway. What else is there to do? Whatever you do, you have to do it now.

Sneak outside the room.
