GuncraftZE is a modded map that was probably inspired by Call of Duty Zombies. It is a really intense survival minigame that is probably more enjoyable than the original game itself. In this map, you have to use weapons such as rifles, pistols, and a knife to fight yourself through waves of zombies. Currently, there is just one available map to play but in the future more will likely be available because it is freaking awesome.

How to play GuncraftZE?
Once you have entered the world you will find that you are in a small room. On one of the four walls in the room, you can tap on a sign to select and enter a map. Right now, there is just one map.
There are some signs in the map which can be used for upgrading your weapons and purchasing more ammunition.
There is really no way to complete a map without dying. So basically you will have to die until you are done.
In the top right corner of the screen, you will see a SHOOT button which you can press to fire the weapon that you are holding in your hand.
Here you can also keep track of your kills, rounds, and points.
