Ok, I decided that what Im making is going to be a zombie DM. I have a hill with the safe house where you start out at, and a 1/4 of the way safe house. There will be multiple levels. The first level will be out doors, but I need some ideas on what to put out there. The second level will be indoors, in some building, but I dont know what will be in the building thing. the 3 level will be in a city, but you start out in a parking garage. then the 4th level will be A train station.
Feel free to post your ideas about this, thank you.
