Zombie MODS For MCPE

This update makes a significant amount of change to Z1 Zombie spawning mechanics. Zombies now spawn at chunk load and at no other time. This means that once you clear an area of zombies and fortify it, it will stay clear for good.
Since the presence of zombies at world spawn will inevitably cause many early deaths in survival worlds, players now spawn with a backpack. Inside the backpack is some food, a wood sword, a few grenades, and a tent. Additionally, it contains a writable book containing the player's basic backstory.
This update also adds a new structure, the stilt house, and an entity, the Survivor. Survivors spawn in stilt houses (which are basically houses on stilts, as the name suggests), and have similar AI to soldiers. Additionally, you can trade with Survivors to obtain items otherwise unobtainable in-game (other than in dungeon chests) (such as chain armour and saddles).
Also, some of you may have noticed that chests in armoured villages are empty. Village houses and stilt houses now each contain a randomized backpack containing random loot such as food, saplings, and other cheap items. They also very rarely contain a gun.
