Pixel art for a dark 2D side-scrolling action game set in China's Three Kingdoms era, around 200 AD. Muted low-saturation palette of dark blues, slate greys and earth browns with very small dull red accents. Large crisp pixels, flat shading, no characters, no people, no text, no UI. A ground texture that fills the whole image edge to edge with no horizon and no sky, seen from above at a slight angle: trampled muddy battlefield earth with cart ruts, small stones and sparse tufts of dead grass. Even dim lighting, evenly detailed everywhere, tileable.
