6. Nether Fortresses
So weve all been to the Nether (Right?), after all it is the only other world in the Xbox version. It's populated by a few Mobs, the main one being the Zombie Pigmen, who are pretty cool, but what do they do all day? Just stand around and wait for you? No, this would make no sense... Surely they build or mine or something, and thats exactly what they do since update 1.9pre1. Nether Fortresses are made from a new block called Nether Brick. These fortresses are similar to Strongholds, which can be found in the over-world (not in the Xbox version yet). These structures consist of a bunch of rooms and corridors, and although that can contain some nasty enemies, they also have cool things like chests filled with booty.
