This is a post-apocalyptic wilderness survival roleplaying video game set in ruins left behind by an ancient civilization that has since crumbled into dust years ago on Earth's surface after their sun went out as part of some catastrophic event or series events, leaving only remnants like this world. The story revolves around the player characters and NPCs surviving for extended periods until they finally die from various reasons such as hunger, dehydration, exposure to radiation/chemicals in air etc., while exploring these ruins with a deck of cards that are called Ruins which represents different buildings scattered across the game landscape.
