This modpack, best played with friends using the essential mod. But still can be played solo. Taking in new world generation mechanics and plenty new biomes, your realm should remain diverse. With mods that add to combat mechanics and ancient and medeival equipment, you should gear yourself well for the beast through the ice and fire mod. But survivale isnt that simple with the tough as nails mod, and a mechanic that uses flint tools. Making wood and stone tools uncraftable. But abviosly this mod pack isnt as simple as it sounds, there are plenty of aspects to real you in to the emersian of the modpack itself.
Also, because i cant seem to remember this but, turn on the resource packs at the beggining except for programmer art and high contrast.
Wish you luck on your journy.
