What Is Sprunki Crimson Cataclysm Phase 4?

Crimson Cataclysm is a multi-phase horror saga in the Sprunki community, and Phase 4 is one instalment of it. The reason it stands out is production rather than premise: UC Cat built it as sole director, designer, animator, composer and cutscene maker, and finished the work in twelve days.

Pepper, who also goes by РЭД анархий, contributed additional design work and sound recreation.

For a scene where most mods are one person swapping art and audio into an existing shell, a self-directed multi-phase saga with original cutscenes is an unusually large undertaking.

How It Plays

Like the rest of the Sprunki family, this is a drag-and-drop mixer built on the Incredibox format. You pull a character from the tray into an empty stage slot and it starts looping one layer of the track; pull it back off to drop that layer. Loops join on the beat, so anything you stack stays in time. There is no score and no way to lose.

Before You Play

  • Free and browser-based.
  • Horror content — this is not one of the bright builds.
  • Earlier Crimson Cataclysm phases exist if you want the saga in order.
