CounterSide Developer Note #40 – Oct 2025
This is Kim Hyun Soo, the Head PD of CounterSide.
We thank all our CEOs for the support and love they have shown to CounterSide.
In this month’s Dev Notes, we’ll provide more details about the upcoming updates during November.
[Omen – ???]

November will begin with the scheduled Omen Episode 3.
Following Campamento and Lotus, Episode 3 unfolds in a brand-new region — we hope you look forward to this next chapter.
We had previously promised to release Omen episodes at three-week intervals. However, additional time is required to prepare Omen Episode 4.
We sincerely ask for your understanding, as Episode 4 is now planned for release in December.
We deeply apologize for not meeting the timeline we had promised.

[ New Awakened Employee – Children of Yaldabaoth Knight of the Lake ]
The Knight of the Lake, who has long challenged our CEOs as a Danger Close boss, will now make a debut as an Awakened Employee.
The Knight of the Lake is a Counter/C.O. type employee — a versatile Ranger capable of delivering all-around attacks.
He suppresses enemy sustain by stealing their healing, and each time an enemy is defeated, he unleashes an enhanced attack that inflicts massive damage and applies a specific crowd-control effect.
Additionally, upon using his Ultimate Skill, his next Ultimate becomes enhanced, unleashing even greater power.
We hope you look forward to the Knight of the Lake, reborn as an Awakened Employee.

[ New Counter Pass Employee – Ascella Procenica]
Following the charming debut of Treasure★Hunter Mi Rinae, Ascella Procenica will be joining as the next Counter Pass Employee.
Ascella is a Counter-type Defender with the Fury attribute — an employee capable of performing versatile attacks.
Despite being a Defender, she can mark enemies positioned in the backline, and each time she uses her Special Skill, she strikes marked targets remotely, showcasing a distinctive combat style.
◆ Ascella Procenica

[ New Operator – Natalia ]
In November, a new Operator — Natalia — will also make her debut.
Natalia enhances the offensive capabilities of Ranger and Sniper employees, allowing them to deliver powerful bursts of damage.
In addition, she can summon Baba Yaga to provide supportive fire, assisting allies in combat.
◆ Natalia

[New Contents – Great Expedition]
The new content Grand Exploration, first introduced during the Half Anniversary, will officially launch in November.
Grand Exploration is a limited-time event mode where CEOs can embark on expeditions using the employees, ships, and resources provided within the event.
During your expedition, you will acquire various employees, artifacts, and other items, which will help you progress further through the content.
Unlike other modes, Grand Exploration allows only four squad members to be deployed at once — this adjustment was made to improve visibility and ensure balanced difficulty. Additionally, based on feedback from our CEOs, duplicate deployments will now be available for this mode.
As you explore, you’ll be able to upgrade your employees, and even enhance your ships into higher-rarity versions. You will also earn Enhancement Points by clearing stages, which can be used to further strengthen your team.
We hope you look forward to this new content, and more detailed information will be shared in the upcoming patch notes.
[New Prestige Service]
The ongoing Black Swan’s Oath Prestige Service will conclude on November 19, after which a new Prestige Service will begin.
The next Prestige skin will feature Final Phase Sigma. We had hoped to present a new side of Sigma, who has long played the role of the CEOs’ adorable daughter.
However, due to delays in the skin production schedule, the new skin will not be ready for unveiling at the start of this Prestige Service.
Therefore, unlike previous Prestige Services that focused on a specific employee’s skin, the upcoming Prestige Service will allow CEOs to choose one skin directly from the lineup of past Prestige skins.
If you wish for one of the previous Prestige skins you will be able to select one, or if you wish to acquire Sigma’s Prestige Skin, you will be able to select Sigma’s skin once it is officially updated.
We sincerely apologize for the delay in the release schedule of Sigma’s skin, following the Horizon case. The Prestige Skin [Clockwork Girl – Final Phase Sigma] is now scheduled for release on December 17.
◆Clockwork Girl – Final Phase Sigma

Lastly, we sincerely apologize for the disappointment caused by the unavoidable postponement of both the Omen Episode 4 update and Sigma’s Prestige Skin release.
As an expression of our deep apology for the schedule delay, we have prepared the following compensation:
◆ Apology Reward
- 2,000 Quartz
- 100,000 Eternium
※ Available for all CEOs who log in by November 7, 09:59 (UTC-5).
※ The reward will expire 7 days after the time it is received via in-game mail.
Although the weather may vary depending on where our Global CEOs reside, we hope every one of our CEOs stays safe and sound.
