The Nether (Also referred to as "The Nexus" in Notch's Blog on Tumblr and was previously known as Hell and The Slip) is part of the Minecraft Halloween Update. It exists in a completely different world from the normal world above. The terrain is dimly lit, full of lava streams flowing from the ceiling, sudden cliffs, and lava lakes, making it extremely dangerous to explore. The ceiling and the base of the Nether are made of bedrock. Mushrooms are also commonly found. If the player dies in the Nether, they will be transported back to the spawn point on the surface world. Maps can be made of the Nether, but they can only be created while there. If a player brings a map of the Overworld into the nether it will stay the same but the marker that represents the player will be absent.
The portals are made by creating a 4x5 (2x3 on inside) door frame out of Obsidian and then lighting the inside of the frame on fire with flint and steel or lava. The corners of the frame may be left out, using only 10 obsidian as apposed to the usual 14. When you stand inside the portal for the first time, it will create a portal in its equivalent area of the Nether. A loading screen will appear during the change of worlds.
A portal can be shut down if part of the obsidian frame is removed.
When re-entering the normal world, any distance covered in The Nether is multiplied by 8, effectively making The Nether a fast-travel zone that allows for greater distances to be covered in a short amount of time in the normal world.
Walking through a portal will not teleport the player―in order to use them, the player has to stand still inside the purple haze. Currently, they will not transport mobs or minecarts. Attempting to go through a portal while in a minecart will result in the player needing to restart the game to continue.
Mobs and EnemiesEdit
Mobs that spawn in the main world do not appear here, except Zombie Pigmen which appear in the Overworld when Pigs are struck by lightning. Instead, there are special mobs that appear only in the Nether (although Ghasts have an extremely small chance of spawning through a portal on the surface world.)
- Ghasts ― Flying jellyfish-like monsters that shoot fireballs. They can be damaged by any conventional weapons, but they do not get hurt when on fire, only when touching it. A Ghast can fly into lava falls or lava lakes, but even if they burn they don't get damaged (As of the November 10th Update). The fireballs they shoot can be deflected back at them using a fist or any tool by hitting it just before impact (shooting an arrow or using the fishing rod on the fireballs works too). They drop gunpowder and Ghast Tears. Ghast fireballs do not destroy cobblestone. Most people when building a fort or house in the Nether use cobblestone to create a safe place.
- Zombie Pigmen ― Neutral, humanoid creatures that turn hostile when attacked. They now drop Rotten flesh and gold nuggets when killed. They weild gold swords, and cause 2.5 damage. Attacking one causes all nearby Pigmen to attack you too, just like overworld´s Wolves.
- Blaze ― A hostile mob that appears in Nether Fortresses. They shoot 3 fireballs like a Ghast, although they do not cause explosions on impact. They drop Blaze Rods.
- Magma Cube ― The nether's equivalent of a slime. When Magma Cubes jump they will show their layers.
Blocks can be brought to and from the main world. So far, there are six block types only found in the Nether:
- Netherrack- This block burns indefinitely, and is the main block type forming the Nether. Setting these on fire while travelling in the Nether is a great way to save on torches.
- Glowstone- A golden block that glows indefinitely, commonly found as stalactites on the ceiling of the Nether. These can be used as a light source underwater on the surface world, and the powder produced when it is mined is suspected to be an ingredient in making lanterns.
- Soul Sand- A brown block resembling a creeper face. When walked on, it slows the movement speed of the player and mobs that walk across it, and makes them sink down a tiny bit. It can be used to create minecart-only passageways and docks.
- Nether Brick- A dark purple stone that superficially resembles bricks. Nether brick can be used to make Nether fence, and can be broken easily with a stone pickaxe. It can be found in the Nether, specifically in strongholds.
- Nether Fence- A dark purple fence. It can be mined in the Nether strongholds, or can be created from six Nether fence pieces.
- Nether Stairs- A dark purple stair. It can be mined in the Nether strongholds, or can be created from six Nether Bricks.
Water cannot be brought to the Nether due to the fact that all water placed will evaporate immediately due to the extreme heat and will instead turn into steam. However, you will have no problem placing lava in the Nether and placing an ice block will have no effect. Breaking the ice block will somehow let water into area.
- If a Bed is placed at The Nether and is right-clicked on, it will explode with a lethal blast radius (unless the player has enough armor).
- If you bring a bucket of water into the nether it'll dry up before you can use it.
