Mods included are the abyss, better end, better nether, and ice and fire. There's also a couple mods adding new creatures to the game. The Nether and End have been modified to add more creatures, mobs, and biomes, as well as many different resources included which can be used to make better armor and tools. In addition to this, the abuuss mod has been added, which takes you to a new dimension when you sleep in a bed, where you can mine (and craft!) more tools.
