Castle was the largest survivor community left in the post-apocalypse. It was supposed to be the safe place. Now it is gone. A small group escaped the zombie horde that destroyed it, fleeing into the wasteland with almost nothing. You are their Commander. While retreating, you find a strange building jutting out of the ground — a structure that does not fit the landscape. With supplies exhausted and no better options, you go inside. What you find becomes the foundation of a new attempt at survival. A zombie apocalypse base-building strategy game about starting over after the last safe place falls.
