Smilegate has released the second content update for Chaos Zero Nightmare Season 5, expanding its Galactic Disaster storyline with a new Combatant, Partner, gameplay systems, and limited-time activities. Released on November 13, 2026, the update continues the story of the Captain and their party as they investigate the Chaos known as Celestial Bulwark on the frozen planet Nivalis.
The biggest addition is Blazebell, the head of House Freyja, who becomes a playable Justice-attribute Controller. Her arrival also introduces Vivian as a new Partner, bringing additional defensive and offensive support options. Alongside the new characters, Smilegate has reworked the boss-hunting mode The Great Rift and introduced several quality-of-life improvements requested by players.
The update also opens a new Supply Store and adds events that provide Crystals and Combatant Growth Currency, giving players more activities to pursue during Season 5.
Blazebell and Vivian join the Season 5 roster
The second chapter of Galactic Disaster follows the Captain and their team as they rescue Blazebell during their operation inside Celestial Bulwark. The head of House Freyja holds a deep resentment toward the Empire, and the new storyline will gradually reveal the secrets behind her past.
Blazebell’s combat abilities revolve around fire-based attacks and card manipulation. Her core card, Fluttering Embers, grants Action Points (AP) and draws additional cards, allowing her to support teammates while improving the party’s combat options.
The update also introduces Vivian as a Partner. She increases the Defense of her assigned Combatant and can strengthen Justice allies by boosting their damage and Critical Chance, depending on how the Bind mechanic is used.
Players can also visit the second Supply Store in Celestial Bulwark to obtain various rewards, including an Omega Code. This item allows players to perform Ego Manifestation (Transcendence) for a Combatant of their choice.
The Great Rift receives separate casual and competitive modes
One of the update’s major gameplay changes concerns The Great Rift, the boss-hunting activity where players previously competed for rankings. Smilegate has divided the mode into two separate experiences.
Subjugation Battle allows players to challenge bosses and experiment with different team compositions without competing for leaderboard positions. Meanwhile, Merit Battle preserves the ranking-based competitive format for players who want to test their strategies against others.
The update also adds Boss Strategy information and Recommended Formation suggestions. These features are designed to help players understand boss encounters and choose suitable Combatants before entering battle.
Another notable addition is the long-requested Battle Speed feature, which makes combat faster. Combatant progression also receives improvements through Divine Epiphany Removal and Memory Fragment Substat Selective Crafting and Readjustment. Players can further customize their Profiles, Save Data, and ID Cards.
New events offer Crystals and progression rewards
The limited-time Flame That Illuminates Memories event celebrates Blazebell’s arrival and explores her past through missions. Running until December 2, 2026, the activity rewards players with Crystals and Growth Currency.
The ongoing Nightmare Dream Park event also receives additional content through a new minigame called Rules of Good Order. Players can complete challenges involving tasks such as repairing rides in the Dream Park to earn further rewards.
Smilegate Head of Business Kim Joo Hyung highlighted the update’s focus on accessibility and player choice, stating, “With The Great Rift’s Subjugation Battle, players can now freely test various strategies without the pressure of competition.”
Chaos Zero Nightmare is free to play on PC, iOS, and Android.
