Mastery Expansion Beta Weekend Now Live

Good news, everyone! The open beta weekend for the Mastery Expansion has begun! Right-click Core Defense in your Steam library, go to properties, select the betas tab and then choose the beta branch.

To allow you to test all the content, you immediately have access to 30 mastery points without having to level up and beat all difficulties first. After the beta, your mastery pages will be reset, but you keep all progress.

Please join the Discord server if you haven't already and do share your feedback with me! I can't wait to hear what you guys think about the expansion!
