Zombie: The Putrescence

Zombie: The Putresence was part of Black Dog Game Factory's World of Shadow setting for a short time. Due to metaplot developments, the Revenants of Revenant: The Ravishing became Zombies, and the game line name was changed. The change lasted until Jason O'Kelly became the game line's developer, and he decided to retcon "all that second edition bullshit."

Background Information
Zombie was a parody of White Wolf Game Studio's Vampire: The Masquerade RPG.
