Right now, I have four new dimensions the deep dark the floating islands the overhaul dimension and the deep peaks. To get to the Deep Dark dimension you go to the portal like structure in the middle of the ancient cities and light t with its designated igniter. To go to the floating islands dimension you place dirt blocks in the shape of a nether portal but beware if you do not go in quick enough the dirt will turn to grass, and you will have to ignite it again. To get to the Deep Peaks dimension you must place stone bricks in the formation of a nether portal. And for the Overhaul Dimension you place stone in the formation of a nether portal. There are also a couple of mobs added including Joseph Stalin who when killed drop the USSR Anthem. And there is also a mysterious figure lurking across some of these added dimensions. There is also a new painting called Great Lenin.
