You're basically limited by your imagination. Minecraft realms A second realm was added to Minecraft, allowing faster travel through the huge worlds. Called The Nether, it resembles Hell, and is full of flowing lava and monsters. You can access The Nether using portals made from Obsidian you have mined. Also, when you create a new Minecraft world, it will now be more varied, with 'biomes' of different landscape, like desert, tundra and snow. NPC (non player characters) now roam villages, which can serve as early shelters for you at night, if you can find them!
