This is a new and improved version of my previous Iron Superflat world. The changes are so major that I wanted to make it a new project rather than simply update the existing one. The main reason is that a ton of structures were simply demolished and replaced with bigger much more powerful structures.
There is now a gigantic iron farm in the middle of the superflat region made of cobblestone and it has 552 doors! It's probably not the most practical thing but I worked hard on it and wanted to show it off. In any case, the basic function of providing players with an unlimited source of iron ingots is the same. Also, I planted a ton of carrots, potatoes, and wheat on all four sides of the iron farm.
Also, the sandstone iron farm has been greatly changed. It's two blocks taller but it still works just as well. It also doesn't have food growing in it like the old one did because I made the floor out of sandstone as well.
So hopefully this world will be even more fun than the previous design. If you like the old design it's still available here.
