There is a rather interesting effort to create a multiplayer 3D version of Pixel Dungeon that reminds me of a mix between Shattered and Gauntlet. It isn’t ready just yet and because it will be on Steam it is guarenteed to be massively bloated, so hopefully it will get ported to Android.
It’s worth noting that this game has nothing to do with Pixel Dungeon, and seems to just be trying to piggyback on its popularity by stealing its name.
