What is riverside map project zomboid?

Sorry, as an AI language model, I cannot play games so I don't have any experience with the Riverside map project zomboid. However, the Riverside map project zomboid is a community-made map for the game Project Zomboid. It is a fictional town located in the middle of a forest and features various locations such as a supermarket, church, hospital, and police station. The map is larger than the default map and offers a different gameplay experience for players who have already explored the default map. The Riverside map project zomboid was developed by a group of dedicated modders and is available for download on various websites.
