Abstract Game Art Styles

This is a style that doesn't usually fit under any existing style,  it means that the designers have done their own thing and make something that is unique. This can still coincide with other art styles and make, for example, a photorealisic abstract art style. This is an example of an abstract art style, you can tell this by looking at the picture an noticing that it isn't made of 3D models that make up most games. But rather made of 2D images that are darkened and given some depth which makes this stand out.
