The End of the World differs from the majority of RPGs in which players take on the role of a fictional character. In this game, players play themselves, and have to make due with whatever gear and supplies are close at hand. Players use their own physical and mental attributes to create the in-game versions of themselves.
Each scenario within the individual volumes functions as a different campaign setting with the same theme. In Zombie Apocalypse, the first of the volumes to be released, each scenario varies in the origin of the zombie plague, in the government’s response, the timeline of the apocalypse/post apocalypse, and the ways in which you can kill zombies, to name just some the many differences that keep the game fresh. Because of the flexible apocalypse/post apocalypse scenario structure, adventures can vary widely in length (particularly if your character doesn’t make it to the post-apocalypse phase).
