Details are scarce at this time, but we’ve learned that Hyrule Warriors: Age of Calamity will, in fact, be getting an expansion pass.
The aforementioned expansion pass, which is basically just a glorified name for DLC or a season pass, is currently available for pre-order. Paying the twenty dollars will entitle players to two separate waves of content, the first of which will release in June. The second is planned for November.
