Zenless Zone Zero’s Rerun Event: Secure S-Rank Agents & W-Engines with Special Guarantee

Zenless Zone Zero is rolling out a highly anticipated engagement for its community: the Selectable Signal Search event, set to run from January 21, 2026, at 12:00, until February 5, 2026, at 14:59 (server time). This special period empowers players to meticulously choose their desired S-Rank Agents and W-Engines, facilitated by an impactful Special Guarantee system. Whether you’re aiming to complete your collection, enhance your competitive edge, or simply looking for optimal free-to-play improvements, this update offers an exceptional chance for strategic advancements.

This exclusive engagement, known as ‘Exclusive Rescreening & W-Engine Reverberation,’ will be active for the specified duration. During this window, participants can engage with distinct banners for S-Rank Agents and S-Rank W-Engines, both incorporating the crucial Special Guarantee. A notable incentive includes a 20% reduction on the initial ten-pull for each banner category. Furthermore, players can partake in dedicated ‘Audition’ stages, providing an opportunity to test the featured Agents and earn valuable rewards upon completion.

Rerun Schedule for Agents & W-Engines

Both the ‘Exclusive Rescreening’ banner for S-Rank Agents and the ‘W-Engine Reverberation’ banner will operate as a single-phase event from January 21, 2026, at 12:00, through February 5, 2026, at 14:59. The featured S-Rank Agents are Alice (Physical), Anby (Electric), and Astra Yao (Ether), while the prominent W-Engines include Practiced Perfection, Severed Innocence, and Elegant Vanity. Please note that all timings are based on local server time, as officially specified.

Understanding Banner Mechanics

A critical aspect of these banners is the Special Guarantee: your very first S-Rank acquisition from either event type is assured to be the specific unit you’ve selected.
Additionally, a 20% markdown is applied to your initial ten-pull on each distinct banner, a benefit that is not repeatable within the same banner and cannot be combined with other offers.
It’s important to remember that any unutilized discounts or untriggered guarantees will not transfer to subsequent rerun events.
Furthermore, the guarantee and pity tracking systems function separately for Agents and W-Engines. Official sources did not provide detailed drop rates.

Strategic Pulling: Advice for All Players

This event presents a significant advantage for various player profiles:

For Completionists: This limited window offers a rare chance to secure a specific S-Rank Agent or W-Engine, crucial for expanding your collection or acquiring key synergy components.
For Free-to-Play & Budget Players: With approximately 90 Encrypted Master Tapes (the typical hard pity threshold) saved, you’re well-positioned for a highly secure pull, making this one of Zenless Zone Zero’s most reliable banner opportunities.
For Meta & Optimization Focused Players: The spotlighted S-Rank Agents—Alice, Soldier 0 – Anby, and Astra Yao—each occupy vital roles within the game’s meta. Astra Yao, as a Support, and Alice, an Anomaly specialist, are particularly adept at enabling innovative team compositions, making them top considerations for many squads.

Key Details of the Special Guarantee

Flexibility in Selection: You retain the ability to alter your chosen featured Agent or W-Engine at any point before making a pull. However, once the Special Guarantee activates (signified by your first S-Rank acquisition), it becomes expended for the duration of the event. Therefore, deliberate planning for your pulls is advised.
Separate Systems: The Special Guarantee operates independently of the standard pity system. It takes precedence, resolving your selected S-Rank first, after which your regular pity count resumes progression.
Resource Efficiency: While a 20% markdown on a single ten-pull might appear modest, over the lifespan of your account and when compared to standard banner costs, this period offers a notably more generous proposition than many typical reruns or initial character releases.

Considerations for Long-Term Strategy

It has been confirmed that the featured units will not be introduced into the Star-Studded Cast Stable Channel (the permanent standard pool) within this current patch cycle. Should your strategy involve waiting for entirely new Agents or the return of less common side characters—details not yet officially divulged—you might opt to conserve your resources. Nevertheless, for purposeful upgrades, this event represents one of the most dependable windows available.

Optimizing Your Squad: Agent & W-Engine Synergies

Understanding how these characters integrate into teams is vital:

Alice (Physical – Anomaly): Excels within dedicated mono-Anomaly compositions but also demonstrates versatility in mixed supportive/damage-focused team structures.
Soldier 0 – Anby (Electric – Attack): Functions exceptionally as a primary damage dealer in Electric-aligned teams, thriving with extended field presence and efficient trigger activations.
Astra Yao (Ether – Support): A highly adaptable unit, Astra Yao can be integrated into most top-tier teams to provide Ether application, bolster team survivability, and amplify damage output, making her a strong recommendation if your roster lacks a premier Support.

Matching W-Engines for Peak Performance

The featured W-Engines—Practiced Perfection, Severed Innocence, and Elegant Vanity—are specifically designed to complement the roles of their respective Agents (Anomaly, Attack, and Support). For players who have previously acquired these S-Rank Agents, obtaining their signature W-Engine represents a substantial increase in power and effectiveness.

Participating in ‘The Final Callback – Classics Rescreening’

This accompanying event provides an excellent opportunity to engage with the featured content:

Prerequisites: To access this event, players must achieve Inter-Knot Level 8 and have successfully unlocked the Events section within the Main Story Prologue – Intermission.
Availability: The event mirrors the banner duration, running from January 21, 2026, at 12:00, through February 5, 2026, at 14:59 (server time).
Experience the Agents: Within ‘The Final Callback,’ you can take Alice, Anby, and Astra Yao for a spin in dedicated audition stages. Each stage clear yields a valuable one-time reward.
Our Suggestion: Even if you’re not planning to use your pulls on these banners, completing these trial stages is highly recommended. It’s a source of complimentary resources and allows you to firsthand experience these powerful S-Rank characters before making any spending decisions.

(Visual Guide Tip: Imagine an in-game display showcasing S-Rank Agents and their unique traits, guiding players through the selection process for Agents or W-Engines.)

Essential Pre-Event Preparation

Before diving into the event, consider these preparatory steps:

Gather Encrypted Master Tapes: Aim for a reserve of 90 or more tapes to ensure you can reach the S-Rank guarantee; strategic planning of your pulls is key.
Evaluate Agent/W-Engine Abilities: Utilize the Audition or Event trials to personally assess gameplay mechanics before committing your resources.
Maximize Resource Collection: Make sure to clear your daily and weekly resource limits to align with the event’s availability, ensuring you have ample materials and currency.
