Deep Down producer Kazunori Sugiura has said Capcom hopes to announce details about the game's beta later this month.
A Deep Down beta was originally due to begin around PS4's Japanese launch in February, but is now scheduled to kick off this summer.
According to a NeoGAF translation, Sugiura said this week: "Details on the public beta test are likely to come in July. There's no excuse, as everyone was looking forward to the information. Rather than development circumstances, we're discussing with the higher ups the policies for the beta test.
"As an apology, I'm attaching a screenshot of the game in development. It's a dungeon themed after the emotion of 'Anger.' I will report again in July."
In development at Capcom Online Games in collaboration with SCE Japan Studio, PS4 exclusive Deep Down will be free to play and will support four player co-op.
The game has only officially been confirmed for release in Japan, but a western launch may be on the cards too. Capcom filed a Deep Down patent application with the United States Patent and Trademark Office in July 2013.
