Pocket Gamer reports that GungHo Online (Puzzle and Dragons) and Supercell (Clash of Clans and Hay Day) are working together to promote each other's games with in-game features. Puzzle & Dragons will add Clash of Clans content, including a themed dungeon and exclusive monsters, while Clash of Clans and Hay Day will feature cross-promotions for Puzzle & Dragons.
“It is an honor to announce the collaboration of Puzzle & Dragons and the Supercell games, Hay Day and Clash of Clans,” said Kazuki Morishita, President/CEO and Executive Producer of GungHo Online Entertainment. “Supercell and GungHo share the same approach to game development so it seemed only natural to collaborate together.
