Tempus Mortis

From the introduction:

Tempus Mortis is fundamentally a character driven adventure. That is to say, it relies on the interaction between the characters more than it does on a narrative arc. There is the vague outline of a deeper story in the questionnaires, but the development of this storyline is very much dependent on the creativity of the players in answering the questions. The basic plot for Tempus Mortis is going to be familiar to most fans of the zombie genre. The players are all victims of a town overrun by zombies. In this case, the zombie infection is the result of experimentation on the town’s populace by an unnamed biotech firm. This experimentation has been done with the cooperation of the city’s mayor.
