The vampires (evil blood-sucking immortal creatures of the night), like the ones from Dracula films, Dark Shadows, etc, will take over the world, while you must all survive.
There is no known cure for being vampirified, so if you die and become a (forever-alive) blood-sucking vampire, you can't rejoin.
The economy has collapsed, so certain services (police, fire department, hospital, etc...) will not be available, and neither will stores be open (however the items will still be inside). You can raid, but this comes with a price. Government guards line the streets, and if you are caught raiding someone, they will shoot you.
Right now, you are in a small apartment building. The other players are in rooms next to you, all on the floor 13. In the room there is a table, one chair, a couch and a painting. What do you do?
