Some fans have noticed that the Adventure Mode button on game creation now mentions the Devil’s Hand as one game type, along with bounties and adventure mode. This is news to new people and curiously memory refreshing to those of us who have been following the datamining for a long time. It’s not anything that’s actually going to happen in the game, as the Devil’s Hand is not Returning, despite Adventure Mode tooltip.
…it could also be an old description that just might have found its way back.
Nevalistis: This is actually the case here. It seems the description of Adventure Mode from a previous build somehow wormed its way in to this particular patch. =( I apologize for any confusion this may have caused.
One thing you learn if you ever look at the code of a video game or any other large software project is that nothing ever seems to get deleted. The code and art assets are all left in there; they’re just disabled or deactivated, or nothing points to them anymore. Thus we always see datamining unearthing all sorts of old artwork and incomplete features in games. Incomplete features actually provided the backbone for some of the best mod-making material in Diablo 1 and Diablo 2, and probably would in Diablo 3 as well, if it wasn’t online-only.
As for the Devil’s Hand… it was never functional in a version of the game that anyone outside of Blizzard got to try, but you can read a lot about it from datamining in the The Devil’s Hand article in the Wiki. We don’t know all the details, but it sounds like an early version of Adventure Mode; a sort of open world play, where players would have gone on a scavenger hunt, following bounties to collect a special suite of items that could be converted into a random legendary item.
