Survival maps are usually about managing to survive with limited resources. They are essentially a custom experience of the survival mode in vanilla Minecraft. They often have certain objectives to complete as well.
A peaceful world, were all seems fine comes to an end. An unexpected quake caused the Earth to shatter into pieces. Can you manage to fix the shattered world, or will you lose your life trying? The remains of the world that are close to you have just enough for you to survive. I wonder how you will prevail?
Is minecraft too easy for you? Is ultra-hardcore mode just not that hard anymore? Do you enjoy unfair maps that try to kill you over and over again? If you answered yes to any of these questions, then boy do I have the map for you.
