Build 41 is the most fundamental and wide-ranging update that Project Zomboid has ever had. We intend it to be a stable foundation for us to build on for many years ahead. For this reason too, however, we anticipate a fairly long public beta while all the various issues presented to us by community testers are spotlit and remedied.Some key features, primarily MP, are initially disabled in the IWBUMS beta build – and will be turned on during the testing process.
