I just learned a new and easy tactic as the Mayans. I call it, Holk Smash! Holk Smash! Is when you rush Holkans to eliminate an early enemy. For instance, a Holk Smash! Is more powerful than a quechua rush. Why? Holkans have 4, and are immune to first strikes. Which is very useful when rushing enemy archer-defended cities early. First off, you need to build a barracks first. This allows you to build holkans with CR1, which provides a small city invasion bonus. Second, you need hunting and bronze working. Which are the techs that enable holkans to be built in any city until you have iron and engineering at the same time. Finally, you need to have about 6-10 holkans to remove a 4 archer city on flat ground, but 10-15 for one on a hill. ( Pain in the butt hill starting locations... ) But the CG and drill promotions make it all worse. You might want to bring some axemen with your force if you have metal.
