Introduction to Zenless Zone Zero The Final Callback Event Guide

The Zenless Zone Zero Final Callback Event in Phase 1 of Version 1.6 is a key opportunity for players to test out featured Agents in curated combat trials. This event is structured to help Proxies evaluate whether certain characters are worth investing in, particularly useful when new banners launch and tough decisions need to be made about spending limited recruitment resources. During the event, players can access special stages tailored to highlight the skills, mechanics, and overall combat performance of specific Agents. These scenarios are designed to offer a clear view of each Agent’s unique playstyle, synergy potential, and overall effectiveness within a squad.

Participation in the Final Callback Event is not only informative but also rewarding. Successfully completing the event stages grants a range of valuable in-game resources. These include Polychrome, the game’s premium currency often used for recruiting Agents; Denny, which is essential for day-to-day upgrades; Official Investigator Logs, a vital resource for leveling up characters; and Basic Certification Seal Materials, which are required for Agent ascension and skill development. Overall, the Final Callback Event is a smart way to make informed recruitment decisions while also boosting your progression with useful materials.

Phase 1 Version 1.6 Specifics

Phase 1 of Version 1.6 in Zenless Zone Zero featured the Final Callback Event from March 12th to April 2nd, 2025. During this time, players were given the opportunity to trial four specific Agents: Soldier 0 Anby, Burnice, Pulchra, and Ben. These Agents were directly tied to the active banners of the phase, offering a practical way to evaluate them before spending resources on recruitment. Silver Anby and Pulchra headlined the primary limited-time banner, while Ben was also featured as a rate-up A-Rank Agent within the same banner pool. Additionally, Burnice was available through a rerun banner, giving both new and returning players another shot at experiencing her abilities firsthand.

Each trial stage was carefully designed to reflect the Agents’ core strengths, allowing players to get a real sense of their performance in combat scenarios. These stages offered structured challenges that highlighted each character’s unique skills, chain attacks, and overall synergy with different squad setups. By participating, players not only gained insight into how the Agents might fit into their current teams but also earned valuable in-game rewards. These included Polychrome, Denny, and character development materials, all of which supported ongoing progression. The event functioned both as a strategic preview and a resource booster, making it a valuable component of the Version 1.6 experience.

How to Participate in the Final Callback

To participate in the Final Callback event during Phase 1 of Version 1.6, players needed to reach Inter-Knot Level 8. Reaching this level unlocked access to the Events feature from the main menu, allowing players to take part in limited-time content like the Final Callback. Once inside the event menu, the Final Callback could be selected, presenting a series of character-specific audition stages. Each of these stages was built to showcase the featured Agents of the phase and provide a practical trial experience.

The trial stages were structured to give players a direct feel for how each Agent performed in combat. These sessions allowed players to experiment with Basic Attacks, Dodge Counters, Chain Attacks, and Ultimate Skills in actual battle scenarios. They also highlighted each Agent’s role in a squad, giving insight into synergy potential and overall tactical value. Here’s a breakdown of each featured Agent and what their trial stage emphasized:

Anby’s trial stage focused on her high-speed, high-burst combat style. As a Physical-type Agent with strong single-target capabilities, her gameplay emphasized quick combos, reactive counters, and aggressive skill chaining. The stage highlighted her ability to dish out damage rapidly while staying agile, making her a strong pick for players who favor fast, precision-based playstyles.

Pulchra’s trial emphasized her role as a support-oriented Agent with debuffing capabilities. As an Ether-type character, she excels at weakening enemies and enabling stronger follow-ups from allies. Her stage demonstrated her crowd control potential and her ability to maintain team momentum through tactical skill usage. Players were able to see how Pulchra’s abilities enhance overall team performance while adding utility to combat scenarios.

Burnice’s audition stage highlighted his control-based kit with Ice elemental skills. As a defensive and zoning-focused Agent, his gameplay focused on area denial and freezing enemies to disrupt their attacks. His trial showcased how he could manipulate the battlefield, reduce enemy mobility, and create safe zones for allies. It was especially useful for players looking to add tactical control and survivability to their lineup.

Ben’s stage showcased his role as a sturdy, AoE-capable Agent. His Fire element skills, paired with strong defensive stats, made him a reliable frontline option. The trial highlighted his ability to absorb damage and retaliate with explosive area-based attacks, making him ideal for players who favor durable characters that can maintain pressure while taking hits.

Each of these stages served as a miniature test run, offering players a valuable opportunity to understand how these Agents functioned in battle and whether they matched their strategic preferences. The trials were not only informative but also rewarded players with materials and currency, further incentivizing participation and exploration.

Rewards for Participation

Participating in the Final Callback event during Phase 1 of Version 1.6 held significant value for both new and veteran players. It offered a hands-on, risk-free opportunity to experience the gameplay of the featured Agents—Soldier 0 Anby, Burnice, Pulchra, and Ben—before making any recruitment decisions. Rather than relying solely on character previews or skill descriptions, players could directly engage with each Agent in combat scenarios specifically tailored to showcase their abilities. This trial format gave players a clear understanding of how each character performed in real-time battles, including their combos, skill effects, mobility, and role within a squad.

In addition to the gameplay experience, the Final Callback also provided tangible rewards for completing the trial stages. These included resources essential for account growth, such as Polychrome, Denny, and development materials that could be used to enhance other Agents in your roster. This meant that even if a player chose not to pull for a featured Agent, they still benefited from participating in the event. The combination of practical gameplay exposure and valuable rewards made the Final Callback a strategic tool, not only for evaluating upcoming Agents but also for progressing your account. It encouraged thoughtful resource management and reinforced team-building decisions based on actual experience rather than guesswork.

Significance of Participating

Version 1.6 of Zenless Zone Zero marked a major milestone in the game’s ongoing evolution, bringing with it a trio of new playable Agents that expanded the strategic depth of team-building and combat. The update introduced Pulchra, Silver Soldier – Anby, and Trigger, each adding unique playstyles and roles to the roster. While Trigger was not featured in the Phase 1 Final Callback event due to her placement in the Phase 2 banner, her addition alongside the other two Agents signified a fresh wave of content for players to engage with.

Among the three, Silver Soldier – Anby and Trigger debuted as S-Rank Agents, while Pulchra was confirmed as an A-Rank Agent. This lineup introduced a compelling mix of roles and abilities. Silver Anby brought a powerful, high-intensity combat style built around rapid execution and Physical-element burst damage, offering a new take on her standard version. Pulchra introduced Ether-based support and debuff mechanics that added versatility to team compositions, especially for players looking to enhance damage output indirectly or control the battlefield through enemy disruption. Trigger, introduced later in Phase 2, came with her own set of explosive, skill-based mechanics and combat versatility.

The arrival of these characters wasn’t just a simple roster expansion—it fundamentally influenced the meta and opened up new possibilities for experimentation in squad formations. Whether players preferred agile DPS characters, tactical support options, or new elemental combinations, Version 1.6 provided fresh tools to shape and refine playstyles. This update gave Proxies plenty to look forward to, both in terms of gameplay diversity and strategic customization.
