Welcome to the Katacombs challenge - backend edition. This workshop will guide you to write a text adventure game inspired by games like Colossal Cave Adventure.

Many times we had the feedback that exercises and katas tend to be too small and focused on learning a specific subject and disconnected from the "real world". We want to present a large enough exercise that will allow us to write "real code" while learning software engineering practices and skills.

We will try to implement a full-featured game using distributed computing, and deal with "real code" issues similar to the ones we find on a "real project". We will provide the REST API, architecture (hexagonal and DDD) and database definitions from where we will start the development. The approach we follow is to have a series of challenges, connected with a user feature. For each challenge, we propose a test to write in outside-in style and then implement unit tests and code to satisfy that acceptance test. We will complete a feature starting in a REST API and following the flow until we reach the end of the feature flow, test by test.

During the workshop, we will divide ourselves in a maximum of 3 mob programming groups that will work on the challenge. Each mob can decide what programming language to use, the only requirement being that a majority of the mob can write and run automated tests, use test doubles and has familiarity with a REST framework.
