Smilegate has released the prologue for Chaos Zero Nightmare’s fifth Galactic Disaster season, “A Promise Upon the Snow,” ahead of its October 21, 2026 launch on PC via STOVE and mobile via the App Store and Google Play Store.
The prologue, titled “Escape from Judgment,” is available from September 30 through October 21. It follows the Captain and their companions after they receive a summons from the Empire and begin a large-scale Chaos investigation. The assignment brings them into contact with several allied factions as tensions grow following the appearance of a mysterious figure claiming to be an Apostle of the Goddess.
The update also adds Anika as a new 4-Star Combatant. Seasonal Combatant Sereniel, who first appeared last December, is returning alongside her Partner, Peko.
Several systems have also been updated ahead of Season 5. The Growth Guide now includes additional missions and rewards for early progression, while the new Aether Cell system adds another source of currency used for character growth.
Full-Scale Offensive has received a UI overhaul alongside new achievements and rewards. Chaos Exploration has also been adjusted so players can more easily check if their Save Data contains specific effects.
Smilegate has also started its first-anniversary celebrations for Chaos Zero Nightmare. A countdown check-in event for the upcoming “Nightmare Carnival” is now live, while two Sereniel-focused events reward players with Crystals and growth currencies for completing missions.
Kim Joo Hyung, Head of Business at Smilegate, said the team hopes players will look forward to the story of Galactic Disaster Season 5 and added that more anniversary events are being prepared for October.
Chaos Zero Nightmare is developed by Super Creative and published by Smilegate. Galactic Disaster Season 5, “A Promise Upon the Snow,” begins on October 21, 2026.
