Hey everyone,

This post has been a long time coming. We've been putting off writing it for a while for a variety of reasons, but the most important is, has, and will always be, our desire to do right by our fans.

It is on this note that we're regretfully announcing the indefinite halt of JC3-MP development. We know you've been waiting for news over this past year - your desire to play it is matched by our desire to make it - but there's a good reason.

Good and bad news often come in pairs, and this case is no exception; several months ago, I (Trix) was approached with an offer I couldn't refuse: to join Avalanche Studios Sweden as a developer so that I could work on projects present and future. As part of Avalanche, I'll be able to bring many of the things you know and love from JC2-MP into future Avalanche experiences, while reaching heights that a mere mod couldn't facilitate. Unfortunately, due to time constraints, neither I or the rest of the team can actively pursue development on JC3-MP; our lives are just too busy to allow for it right now.

We will still be maintaining JC2-MP where appropriate - while we're not actively adding new features, we will fix bugs, maintain stability, and ensure that JC2-MP remains a quality experience for players present and future. We're still searching for solutions to our most prevalent issues (including AMD compatibility without workarounds); hopefully, we'll be able to make headway in the future.

As a closing note, we'd like to thank our loyal fanbase for all the support over the years. While we know we haven't always been the most communicative, our hearts have always been behind our mod(s) and their players. All of us remember the many wonderful moments we had in the beta tests and joining random servers well after release; on behalf of the team, thank you to all of the players, server owners, scripters, and you for everything. We couldn't have done any of it without your ongoing support.

And hey, you never know what might happen in the future - we might see you down the line in another adventure :)
