The Mexico Civilization DLC for Age of Empires III: Definitive Edition is out today, and with it comes update 54545 for the base game. The patch updates the RTS game to make room for the new civ, but it also adds some new features that everyone will be able to enjoy, regardless of whether they purchase the new civ pack.
The patch introduces a long list of improvements to the AI, which should make for more challenging skirmishes. AI players, for instance, will now scout shorelines looking for fish if the map includes them, and it will now figure in poison in its damage calculations, making it more efficient and less likely to ‘overkill’.
Maps have gotten a lot of love, with several classic American maps getting major improvements. The maps for standard and team now include California, Painted Desert, Rockies, Sonora, and Texas. In standard, Siwa Oasis has been removed, while in team, Great Rift has been dropped. Players will see fixes and improvements across the rest of the map set as well, with fixes that address stubborn problems like trade routes and spawns, for example.
