The next major update for Minecraft is shaping up to be a pretty exciting one, and while fans have only gotten a glimpse of some upcoming features so far, the game's current experimental build allows players to see the massive new trial chamber structures for themselves. These procedurally generated subterranean structures are similar in nature to Minecraft's existing dungeons, with the upcoming trial chambers housing specialized mob spawners, new building blocks, and the hostile creature known as the Breeze throughout their many sprawling corridors and rooms.
