Welcome to DOWN UNDER Survival!
This is a very simple map, you spawn under the surface of the world and you have to survive under the ground. There are some basic resources to get you started.

I also created some challenges to do:
1. Grow some trees
2. Make a farm
3. Make iron tools
4. Make iron armor
5. Make an animal farm
6. Make diamond tools
7. Make diamond armor
8. Create a nether portal
9. Find the nether fortress
10. Defeat the wither
11. Make 6 eye of enders
12. Find the end portal and go to the end
13. Defeat the ender dragon

These are just some examples of challenges, but the challenge of surviving under the surface is already pretty difficult!
Make an awesome base and have fun!
