A retro, pixelated space invader design, directly referencing classic 1970s-80s arcade games rather than any generic 'alien' concept — used for gaming culture, retro-tech nostalgia, or invoking old-school video game aesthetics. It's one of the few emoji whose visual design pays homage to a specific piece of media (Space Invaders) rather than a general concept.
