As you've probably heard, since the 1.0 release we've been busy working on new content and on a new game mode for Curious Expedition 2. We've been doing some playtesting already and are now looking for more players to join and give us their feedback.
In order to participate you need to own the game already, but besides that we don't have other requirements. It's not necessary to have completed the campaign.
If you're interested and would like to help please join our Discord server and follow the instructions in the #announcements channel. The playtesting phase is now over, thanks to everyone who participated!
