A recent job listing suggests that the upcoming Kingdom Hearts III could have an online feature/mode of some sort.
The official careers website for Square Enix has a job listing open for someone to work in the Osaka branch. The end of the job description says something about being constantly online.
Here’s a rough translation for the Kingdom Hearts III position:
“In charge of general technical assistance (workflow construction, selection of middleware etc) in Implementing the high quality graphic expression or Kingdom Hearts III. In charge of construction duties for a shader on the game engine for nature representations (water, rain, snow etc) and special effects (magic etc) etc, constantly online games.”
The Kingdom Hearts games have mainly only been single player experiences. It’ll be interesting if an online co-op mode will be added to Kingdom Hearts III. One player could be Sora, while the other two players could be Donald Duck and Goofy.
An online multiplayer mode for Kingdom Hearts III could be a possibility, although this will be a new territory for the series. Online multiplayer isn’t really a mode that suits the RPG genre though.
In either case, we will just have to wait and see what Kingdom Hearts III conjures up whenever it comes out.
