There are dungeons, other new structures, and new animals. The overworld terrain can be changed with terraforged before you create a world however this is optional. The nether and end island dimensions are both completely overhauled and you will find a lot to discover there. Some last things about this pack include some techy stuff with the security cameras and camera mods. There are a few more bits and bobs around that I will leave you to read in the mods list. Oh and by the way you can go to space. Another note, I added a map called Piglin's Path by Luki_exe. This is just because the map is incredible and I thought it would be fun to have for you to try out with the modpack.
