Visually, Axiom Verge looks like an NES game, and it rarely distances itself from that aesthetic. Texture patterns that are unashamedly 8-bit are copy/pasted in every self-contained region. Enemy designs are also wonderfully weird. It’s almost as if they’re two-dimensional Spore creatures. Each environment has its own aesthetic (wooded, gooey, crystalline, etc.), and the enemies often reflect those design sensibilities. It’s an impressively cohesive vision for one of the strangest game worlds I’ve seen in a good while.
I love Axiom Verge’s soundtrack. At first, it comes across as yet another 8-bit soundtrack, replete with chiptune cues and lots of staccato melodies. But then it starts to deepen, and soon progresses into synthesizers and vocalizations. Sound effects, however, remain comfortably in the past: enemies shriek with electronic fervor, weapons report with their own unique onomatopoeia, and even the simple act of running through a door comes with its own sound.
