IndieGames.com: "Notch spread the news last week that Minecraft will be receiving a Halloween update on the 31st October, and just to prove that it's all coming along smoothly, he's posted up a screenshot of a new underground environment on his blog.
Give the above image a click for a larger, even more stunning version. How gorgeous does that look! Even Hell looks beautiful in Minecraft, it would seem. Apparently, this Hell world is a separate dimension that can be used for fast travelling - switch to this underworld, move a few paces then switch back, and in the 'real' world you'll have moved much further! Useful indeed, but just that little bit scary."
