We're getting close to a fully playable Lite Campaign V3 and plan on giving you a sneak peek by releasing a first version as an opt-in open beta before Christmas. That version will have all the main features planned for the LC V3, but not the polish that we would want from a proper release version. Also, to not mess with your saves and limit the scope of potential issues, that opt-in version will only have the LC V3 - no sandbox or exporter (YET!).

There will also be a bunch of new gameplay mechanics coming with the new version. Have a look at our latest Little Dev Update for more information and some examples:

Our target date for the first rough release of the LC V3 is the 21. December 2018. We'll keep you in the loop with dev updates as this date approaches.
If you missed some of the previous Little Dev Updates talking about various features in the LC V3, have a look here:
