Chaos Zero Nightmare held a preview broadcast on the 28th to unveil details for Season 4. Most notably, the team promised a definitive turnaround on the balance changes that had previously sparked quite an uproar among the player base.

The developers began by offering an apology for the balance patch revealed on the 21st, ahead of Season 4. At the time, the patch included several controversial nerfs—such as caps on buff stacking, reductions in seasonal power and combatant performance, and limits on discarding cards—which naturally prompted a fierce backlash from the community.

During the live broadcast, Live Director Choi Seung-hyun admitted, "I have no excuses," acknowledging that their internal review process and response system were simply not up to scratch. Development Director Kim Ki-bum added, "While Season 3 power levels were indeed far beyond our initial balance benchmarks, nerfing them now would have been an irresponsible move that disregarded the time and effort invested by our players." Director Kim further promised that all future seasonal elements would be designed with a power ceiling raised to match the Season 3 standard.

As part of this shift, most of the previously announced balance adjustments have been scrapped, and the Season 4 power card, 'Desire', is actually getting a buff. While the nerf to the controller character 'Orlea' will proceed as planned, players will be able to claim a refund of 'Prism Cubes' and growth materials for three weeks starting from the update on the 29th.

The 'Mutation Core', a save-data enhancement element added during the pre-season, is also seeing improvements. Previously, players could purchase up to 30 units using 4,000 'Black Matter' gathered from 'Sortie' content. Post-patch, players can acquire up to 10 units for 1,000 Black Matter, with subsequent acquisitions costing 2,000 Black Matter each.

Several changes aimed at reducing fatigue were also unveiled. The 'Ether' cost to enter 'Sortie' content is being slashed from 30 to 10, and the refund point for Ether has been moved to the rest area just before the first boss. To reduce the over-reliance on 'Iridescent Fate' in Sortie rankings, points gained through Iridescent Fate effects will no longer be factored into final scores. A 'Sweep' function is also being added to prevent the tedious grind often forced upon players for item farming.

Beyond that, the text is being refined for better clarity, and a character growth guide will be added after the Season 4 update. Furthermore, players can now designate up to three target builds per combatant; the game will highlight the relevant cards and 'Flashes' whenever they appear during a Chaos run.

Following the balance discussion, the team shared more on Season 4. The main stage for this season is the 'Kaleidoscope Incubator', where players delve in to investigate a string of disappearances involving the 'Firsts'. In the process, players will encounter new bosses, 'Vercula' and 'Formica', both of whom possess the Instinct attribute weakness. The previously teased new characters (Hilde, Arabella, and Olga) will feature in pick-up banners at three-week intervals, with Arabella arriving as a seasonal character.

A summer event is also on the horizon. Swimsuit outfits for Hilde, Arabella, and Olga will be sold alongside their respective pick-up banners, and on August 19th, Rei's outfit 'Exciting Summer Vacation' will be given away for free. Various events, including 'Beach Cafe Festival', 'Stella Market', and 'SE-4 BR33ZE', will also offer in-game currency.
