Trion Worlds has announced Trove, its free-to-play online adventure RPG.
The game is described as "an open-ended voxel adventure through countless realms filled with quests, chests, and enemies great and small."
Players can explore and create buildable and destructible worlds much like with Minecraft.
You can sign up for alpha testing through here, which Trion says will help the team "develop openly and collaboratively" with the players.
A release date and platforms other than PC have not been announced.
