Into the Chasm: Guide to First Strata contains the basic rules to create a adventure and go on a simple adventure in a relatively safe area. You will need to fill to come up with description for the artifacts the party find. By itself the document is pretty bare bones. The good news is other one page resources have been released that help flush out the setting. I gave this 5 stars because it felt like a different take on a dystopian future that has gone post apocalyptic.
