The HRA is a sleek, futuristic device with a minimalist yet highly functional design, embodying the game's modern surrealism and brutalist aesthetic. It features a geometric, angular form with a combination of smooth metallic surfaces and textured, grooved panels that suggest advanced technology. The device emits a subtle, luminous glow from its core, with a color palette dominated by cool blues and metallic grays, accented by occasional pulses of brighter energy that hint at its resonance amplification capabilities.
