Hello everyone! Just been working on this map for awhile now. Its really hard and sometimes very annoying building on PE, but here is my work in progress! Once I heard that they confirmed the addition of survival to PE I started building a fortress while I had unlimited blocks, I suggest you all do the same, or just use mine!
Now this was done using an android phone, so if your using iOS than I don't know how you would place this in your game. If anyone knows how to help them please post it here.
As for placing this in the right spot on your android phone, go too: games/com.mojang/minecraftWorlds and you can just unzip the file and place it there! Enjoy!
