GungHo Online Entertainment and Supercell have announced a unique collaboration this week to bring special cross-promotional features to each respective company’s biggest powerhouse game titles.

The games in question are GungHo Online’s Puzzle & Dragons, which will incorporate a new dungeon and exclusive monster types based on Supercell’s wildly popular Clash of Clans franchise. Similarly, Supercell’s Clash of Clans and Hay Day will both be receiving exclusive promotional content based on the world of GungHo Online’s Puzzle & Dragons. This is some pretty interesting stuff here, considering the massive scope and popularity of each of these games; and given how well the two sides seemed to have hit it off, who knows what new and exciting kinds of things this will mean from both camps in the future.

Representatives from both parties expressed their excitement and interest in working together in this manner, and learning more about how each other runs their business. Ilkka Paananen, CEO of Supercell remarked, “We are very honored to work with GungHo and learn from the masters of free-to-play gaming.” Likewise, President/CEO of GungHo Online Kazuki Morishita showed equal admiration, in saying “Supercell and GungHo share the same approach to game development so it seemed only natural to collaborate together. We will continuously support each other and our shared vision of delivering fun and exciting gameplay to everyone.”

The cross-promotional game content by the two companies is expected to launch in all of the participating games on June 24, and will run for two weeks.
