The China Challenge introduces a new thematic map compatible with The Leeghwater Project expansion, featuring three major innovations:
- Landscape Tiles:
18 additional structures covered by construction tiles showing the required building costs. When constructed, the tile is removed to reveal the completed structure and reconfigure the map. Building a Landscape Tile grants a bonus of your choice from the appropriate region level (mountain, hill, or plain).
- New Map - The Yellow River
Introduces two Natural Lakes on the board where water droplets stop if space is available;
- Final Company - China
China joins Barrage as the last company ever, compatible with the base game and all expansions.
