Removed: No Longer Available
Heck was removed from the game files, and is no longer obtainable.
Heck was an underground mini-biome that was characterized by flesh and brain blocks, and unique 'plants' that dropped meat chunks when broken. There were often torches and small pod lights that light up the biome. Heck Altars could also be found here. The biome had a similar appearance to Flesh Caves.
The assets for this biome were removed in update Cheerful Giraffe.
