From the introduction:
Just a normal day. On a walk to work. A woman comes running down the street yelling “He’s after me!” Behind her a young man in jeans and a torn T-Shirt, covered in blood, walks forward with malevolent intent on his face. You call to the policeman shuffling across the road, then notice his left arm is just a bloody, torn stump. “What on Earth?” you think “This is like some zombie movie!” Just then a car comes screaming around a corner, a crazy woman clinging to the roof. The car runs down the policeman and zooms on. This isn’t a movie.
Day Zero : Zombie Apocalypse Campaign is a role playing adventure set in a modern day town as the Zombie Apocalypse is just beginning. The players create regular folks as their characters and plot out how they would go about their day if nothing were happening. The game master then notes where in the city the zombies first appear, and tracks the apocalypse hour by hour until it intersects with the adventure player’s characters.
Then all hell breaks loose.
The players try to keep their characters and loved ones alive until the following dawn, and perhaps save some others. The world around them is rapidly falling apart, and characters that are run by the game master are trying to respond to what is going on, some with competent, and some with foolish methods. The adventurers may try and make common cause with them, or may find they are a complication to the goal of surviving.
How will you survive Day Zero?
