Project Summary
Cataclysm: Dark Days Ahead is a roguelike set in a post-apocalyptic world. Surviving is difficult: you have been thrown, ill-equipped, into a landscape now riddled with monstrosities of which flesh eating zombies are neither the strangest nor the deadliest.
In the course of your ordeal there will be opportunities and temptations to improve or change your very nature.
