Hello!

If you want to get the chance to be invited into opendev, then you need to fill out the form located on the page within this link: https://www.games2gether.com/amplitude-studios/endless-space-2/blogs/731-register-for-opendev-and-leave-your-mark-on-humankind%E2%84%A2 

Scenario 1 and 2 have already released, along with the wave of invites for those two scenarios. So filling this form out now will likely be for the chance to get invited whenever Scenario 3 releases next week.
