How long will Early Access last?
Until the March reaches its tenth age and the curses, the endless mode and offline progress are in. There is no date yet: updates come when they are ready, and the changelog lists each one.
What will version 1.0 add?
Ages VI to X with their lords, more soldiers and guns, the curses, an endless mode and offline progress. The full game, 1.0, is planned for PC and mobile.
