Here is a sneak peek at the armor progression of the lowest tier of standard units, otherwise known as "Light" units.
First we have swordsmen with a simple leather lamellar vest, a wooden shield, and a single-edged dao sword. In general note the new variety in faces, caps, leather color, and shield design, thanks to The Blade That Was Broken.
Next, we have spearmen, armed with either a ji or a ge, with the first armor upgrade for the light units. Essentially this upgrade adds an extension to the vest down the front of the body, places armor on the shoulder connector, and represents generally harder and thicker leather. Units will also do away with their wooden shields (if they have them) and adopt much sturdier bronze shields.
Finally, we once again have swordsmen, with the second and final armor upgrade for the light units. This armor is, in design, the same as the previous upgrade, however what makes this armor different is that it is composed of iron lamellar. Units with this upgrade also upgrade their shields to iron, giving them good quality arms and armor for a low tier unit.
This sneak peek is only the tip of the iceberg. The mod team has a bunch of new additions for the upcoming patch, including scripts, units, models, and graphical enhancements. Release date is TBA, so keep your eyes on the forum for any further information on a release date.
