While the levels make no logical sense in true retro shooter fashion, they do make game sense, all having clearly defined layouts that expertly navigate you through some truly massive environments. One standout is an entire level that takes place within a canyon, with a foreboding level of verticality. The design knows just which cues to provide you, and actually finding where to go is no more challenging than with any other modern game. While many of the environments rely heavily on white tiled walls, as you progress further outside, more colour breathes life into the world, a most welcome change.
