This mod is inspired by Age of Empires 2. I have replaced the default units with seven types of units. Each unit has one type of enemy that it excels against and a second type of enemy with a lesser bonus. This mod replaces the Spanish and Portuguese civilizations. The AI does not make very good use of the new units and will be even easier than normal. Natives and many other units haven't been adapted, yet, so it's best to agree not to use natives with this version of this mod. No new art assets are used.
Note: This mod is a work in progress. I still need to fix some of the artwork. There are, surely, many other things that I should fix. Please feel free to message me with any bugs or suggestions.
