Acquire revealed what the third “D” in “3D” stands for in Yuusha no Kuse ni Namaikida 3D (Badman 3D) and it’s a two player mode called Family Dungeon.
Both players share a dungeon in Family Dungeon and the goal is still to defend your home from invading heroes. The dungeon is divided into two parts, pink and terracotta, for scoring purposes only. If you want to you can break soil and release monsters from your partner’s side, but one of the goals in Family Dungeon is to get a higher grade. It’s part cooperative, part competitive. If the God of Destruction and Musume get captured the game ends.
The mode was announced with a demo video, but Sony hasn’t said how players can connect to each other. Will this support infrastructure mode or is Badman 3D ad-hoc only?
Yuusha no Kuse ni Namaikidia 3D is slated for release in Japan next March.
