Empire City - Salt Mine Upgrade Animation (Spine)

A salt works from Empire City, the ancient-world city builder by Red Brix Wall, animated in Spine through its whole upgrade path.

The shot opens on a bare salt crater cut into coastal rock: wooden walkways, stacked salt blocks, a couple of carts. It ends on a working industry - terraced evaporation ponds filled with brine, boiling houses with fires under their domes, a waterwheel turning on the channel, docks, drying tables and a market row along the cliff.

The crater in the middle never moves. Holding that anchor is the whole trick: every level reads as the same place growing richer instead of a new building dropped onto the map. Each stage is delivered as its own skeleton state, so the team can play a single step during a real upgrade or run the full sequence as store and ad footage.

Animated on the client's own isometric assets, so it goes into the live build without a separate render path.
