No waiting needed
When Dragon Quest Heroesarrives in the west in October on PS4, it’ll sport all of the DLC so far that has been released in Japan, by way of free patches in that region. The game followed a similar strategy to Hyrule Warriors, where updates were released periodically after launch, except in Heroes‘ case, they’re all free.
The DLC includes five major packs (and “more”), which will be unlocked by completing the game and visiting the post office. Said packs include “Alena’s Episode,” Bjorn Battle,” “Great Demon Lord Zoma Battle,” “Nokturnus Battle,” and “Psaro Battle + Playable Character.”
