A listing on the Australian Classifications Board has revealed a possible successor to Steel Diver.
The 3DS game may well get a sequel with the listing titled Steel Diver: Sub Wars, with original developer Vitei seemingly attached to the project. It's believed that this could be one of the smaller projects lead by Mario creator Shigeru Miyamoto, as a potential free-to-play game.
Interestingly, the listing also states that the "gaming experience may change online", which could well be an indication of online play, hopefully.
Would you dive into the experience if a sequel were to be made?
