This was made for an android MMO game, Zombix Online. The game has players explore a post-apocalyptic wasteland, collect resources, and build bases.
The village has pre-made isometric buildings and traders the players can interact with to buy, sell, and store items of various types, as well as to repair and upgrade their equipment.
The wasteland is filled with dead trees and various rubble, as well as run-down bandit outposts the players can capture and outfit with walls, cover, and other objects. The useful type of object is the machines. There is a generator that aids the players in creating a motorcycle, and a mail service machine used for trading. Capturing an outpost allows the players to keep a steady supply of bullets flowing, bullets being the game's currency.
The newest update is going to introduce modular base-building out of roof, wall, and floor tiles.
