I will facepalm if this gets a lot of people.
THIS IS NOT YOUR TYPICAL ZOMBIE RP. It involves the breakdown of the mind.
In a rich neighborhood, there lives this old man (who I'll play as) who had always predicted a zombie invasion. The parents of the surrounding families had always thought of him as insane, always talking about how he should be locked up, but never gets around to reporting him to get him locked up. The children and teens never meet this man, because of how protective their parents are. But the children and teens have always played out, in their minds, what they would do in a zombie apocalypse.
So, the zombie apocalypse happens, and the children and teens are eager to get out there, and survive, smash zombie skulls, and live off the remains of the world. Unfortunately, the children's plans never happen, because their parents are so protective. The parents bring their families to the "crazy" man, offering him money so they could hide in his metallic, underground shelter. The man lets the families in for free, but there's only enough food in there to last for the remaining days of the old man's life.
The old man is a nice guy, so he distributes the food equally. But what do the capitalistic parents do? As they continue to coop their children inside the shelter, they take out their wallets to bribe each other for the food, with the common possibility of offering even $100 for a can of beans. They use threats. They blackmail, they steal, they cheat, they argue, they fight.
And the children and teens? They would roll their eyes and make sarcastic remarks about certain things, plan routes of escape, and make friends.
And you?
This is a psychological RP, where you RP as a whole family, each member bent on going through with their own ideas to survive.
The roleplay starts before the zombie invasion while people ridicule the old man.
