There is a new system neutral post-apocalyptic kickstarter project
DOOMSDAY. The creator did the Exterminator Gamma World article in Dragon #104. I haven't decided whether I'm interested or not but figured some others might be.
There are whispers of new horrors in the night: menacing shadows, blood-curdling screams, and startling tales of a strange phantom pleading for help but terrifying to look upon.
A new threat grows on the horizon; fear hangs in the air.
Will you dare journey to “ground zero” — a remote village in Switzerland where the Large Hadron Collider lies 300 feet beneath dirt and rock — to learn the truth behind the apocalypse and stop a new terror from rising?
DOOMSDAY is an Apocalypse™ adventure pack that launches you on a journey to Switzerland to uncover what really happened at the Large Hadron Collider and prevent an ancient threat from destroying the world anew.
