Happy Dungeons, the action RPG with an emphasis on co-op, is making its way over to PlayStation 4 this fall. Set to launch early this September, Happy Dungeons has been on the radar of Xbox One fans since last year. Developer Toylogic is celebrating the release with a special, limited-time open beta. From Friday, July 21st to Monday the 24th players can join in on the 96-hour Beta-thon for PS4. Anyone looking to take part can do so here.

The beta will be a chance for Toylogic to receive feedback on the game and the changes it has undergone for its launch on a different console. The developers are hoping to try out the matchmaking system, test the server capacity, and to simply hear back about the elements of the game that fans either like or dislike. Furthermore, players can earn special items during the Beta-thon that they’ll be able to access again after the game’s official release.

For those who don’t know, Happy Dungeons is the follow-up to Toylogic’s strategy RPG Happy Wars. Like Happy Wars, Happy Dungeons is a story-driven experience with multiple character classes and customizable avatars. Players are tasked with battling fantasy-type enemies on their way to rescue the princess and help a king in peril.
