The Yue Fei's Legacy expansion is out for Age of Empires IV. At its center is an eight-mission single-player campaign about the great Song Dynasty general Yue Fei and his fight against Jin Dynasty invaders during the Song–Jin wars.
The new Jin Dynasty civilization is available in skirmish, multiplayer and Crucible mode. Its strength lies in cavalry, siege weapons and a mobile economy: mounted villagers gather resources quickly, emissaries establish tributary states, and Meng'an Mouke fortresses automate defense. The arsenal includes unique units: the Iron Pagoda, mounted grenadiers, eruptors and mounted crossbows.
Rounding out the package are four new maps and two new biomes.
