The reunion starts on Friday evening. The game ends on Monday morning. Most of this time is spent on reaching corruption 1. How can anyone ever reach 2 or 3?
Once a corruption level has been unlocked, you can activate it in the end of run menu. While characters all at level 0 aren't lacking for content... this is where the vast majority of the games content is. Many people have not noticed this and the next version will have a popup that explains this.
