IndieGames.com: "The biggest Minecraft update is a long while goes live on October 31st. It's a Halloween themed update, with carveable pumpkins, new baddies and torches that eventually go out. By far the greatest new addition, however, is the new Hell world, or 'The Slip' as it's known.
The Slip is a whole new dimension that allows players to move quickly through the overworld. Moving only a few paces in this hellish lava-filled area allows the player to move much further in the outside world. Entering and leaving The Slip is done via special portals, created out of rare Obsidian. Follow me as we take a trip into The Slip, check out the underworld and meet some of the new enemies."
