A survival map I made, in which you spawn in a giant "crater," or more of a hole, and have to survive with minimal resources. There are a few sets of rules you must follow in order to successfully beat the challenge.

1.You cannot leave the crater.
2.You cannot mine up out of the crater, but you may mine any other direction you please
3.You may build on the walls of the crater, but again, you cannot leave onto the surface.
4.The difficulty must be on Normal or above.
5.You cannot use a program such as 'Invedit' to add items to your game.
6.You cannot mindlessly blast your way out with TNT.

Besides these rules, and possible edits in the future, you can do anything you need to do for survival.
