Once Human: Season 5 gameplay showcases co-op Colossus boss battle, live November 18

What if a sky-spanning Colossus didn’t just loom overhead as a static backdrop, but actively listened and responded to your every gunshot? That’s the core question driving our upcoming fifth season, Dissonant Resonance, free to play and launching globally on November 18. Today, I want to take you behind the scenes to share how we are turning sound and emotion into your greatest weapons – and your biggest threats.

New weird meets a symphony of dread 

Once Human thrives on the New Weird design philosophy – taking the familiar and twisting it into a nightmare. For Season 5, we wanted to apply this philosophy not just to the visuals, but to the audio itself. As we realized players always take background music for granted, we decided to weaponize it.

Inspired by the cathedral pipe organ, a human symbol of sanctity and solemnity, and through the lens of the New Weird, we distorted this familiar object into a cosmic, biomechanical monstrosity: What if the music wasn’t just playing in your headset, but was the literal breathing and judgment of a cosmic monstrosity watching your every move?

This idea birthed the Sky Living-Machine Colossus. By merging the sacred with the grotesque, this massive pipe-organ titan transforms the very rhythm of the world into an active, weaponized mechanic.

Emotion zones & rhythmic gunplay 

To ground this massive concept in actual gameplay, we’ve warped the open world with four distinct Emotion Zones: Joy, Anger, Sorrow, and Fear.

In these erratic regions, your arsenal becomes an instrument. Defeating enemies scatters musical notes across the battlefield. By shooting these notes, you not only trigger pitch-tuned audio to improvise your own battle rhythms, but also collect them to purify dissonant, corrupted scores. Once these notes are rearranged into harmonious melodies, the scores grant your squad powerful rewards. And as you perform these deadly battle rhythms, the Sky Colossus above will react dynamically, shifting its visual expressions in real-time.

Once the Sky Colossus descends and lingers long enough, the world itself splits open—a rift portal emerges, daring your squad to step through and face the music directly.

Conducting the Colossus & a new companion 

Stepping through that portal initiates a high-stakes, four-player co-op Colossus Raid. But this is no traditional boss fight. Taking center stage, the titan becomes a maestro of destruction, dynamically shifting the battlefield’s combat score.

As the boss and the arena pulse to a new rhythm, your squad must adapt on the fly. You need to sprint to silence glowing resonating pipes in a ruined cathedral, and disrupt the melody before the deadly track concludes. You aren’t just surviving a boss fight – you are conducting it.

To help you survive this apocalyptic symphony, we are also introducing the brand-new Deviant, Silent Statue. Appearing initially as a shattered, gray monument, it silently absorbs the elemental chaos of your firefights. For those who can unlock its true potential, the ruins will mend and spread brilliant golden wings—bestowing a massive elemental blessing across the squad.

Gear up, tune your weapons, and get ready to conduct the apocalypse when Once Human Season 5: Dissonant Resonance drops November 18 on PS5!
