Highland Warriors is a standard 3D real-time strategy based upon medieval Scotland in a very William Wallace/Braveheart-esque themed game. Authentic dialect and soundtrack emphasize the "Highland Warrior" feeling.
The engine (ATLAS engine) was built by the developers and uses state-of-the-art technology. It allows each unit to consist of up to 8,000 polygons, and 200,000 polygons on-screen altogether with real-time shading. Each unit and building is very detailed at all angles.
The game also boasts a change of seasons throughout any given skirmish, which can aid you or hurt you, depending on your situation. For instance, farms won't grow during the winter, forcing your workers to find other means to feed your armies, and mountains may be unpassable.
