Zenless Zone Zero Version 2.5: What Every Proxy Needs to Know

By the GenshinBuilds editorial team

As Zenless Zone Zero embraces its Version 2.5 rollout, players are greeted with a suite of strategic modifications designed to enrich the gameplay experience. Key among these are the introduction of the Filmgoer Thank-You Gift event, a significant adjustment to the rewards for duplicate S-Rank characters, and the expansion of city-based funding options. These enhancements not only re-evaluate event participation but also directly influence how premium currencies are acquired and optimized, a crucial factor for free-to-play (F2P) and low-spending players. Here’s a detailed breakdown for dedicated gacha enthusiasts.

The standout improvement in 2.5 is how subsequent S-Rank acquisitions are handled. From the eighth duplicate onward, players will now receive a Special Invitation Letter in addition to Residual Signal, substantially boosting the long-term progression value of these pulls. Concurrently, new methods for accumulating and converting W-Engine Microcontroller Units are set to transform crafting and enhancement tactics for players across mid-to-late game stages.

Version 2.5 Highlights

Update Release: Version 2.5 is now live (specific release date not publicly disclosed).
Featured Event: The Filmgoer Thank-You Gift is available for a limited duration.
S-Rank Rewards: A Special Invitation Letter is now granted upon obtaining the 8th and subsequent S-Rank duplicates.
W-Engine System: W-Engine Microcontroller Units are more accessible through the City Fund, shop, and dismantling options.
Banner Improvements: Official improvements to S-Rank duplicate compensation are now permanent.

Core Adjustments & Upcoming Banners

Refined S-Rank Agent Duplicates:

Effective with 2.5, any S-Rank Agent acquired for the eighth time or beyond will yield one Special Invitation Letter, a notable upgrade from the previous reward of only 100 Residual Signal.
This change is retrospective: Proxies who previously obtained eight or more duplicate S-Rank Agents prior to the 2.5 update will automatically receive corresponding Special Invitation Letters via in-game mail post-patch.

Concurrent Limited-Time Signal Search Events:

The Exclusive Rescreening and W-Engine Reverberation banners will operate simultaneously throughout this patch cycle. (Exact start and end times are not detailed in official announcements; players should monitor in-game notifications for UTC+8 scheduling.)

Signal Search Overview

Banner Type	Availability Phase	Commencement (UTC+8)	Conclusion (UTC+8)	Key Focus
Exclusive Rescreening	Undisclosed	Undisclosed	Undisclosed	Features specific S-tier units
W-Engine Reverberation	Undisclosed	Undisclosed	Undisclosed	Increased W-Engine drop rates
Note: Players are advised to verify precise timings within the game client, as official communications lack specific dates.

System Enhancements & Quality-of-Life: The W-Engine Redesign

Expanded W-Engine Chip Acquisition:

Proxies can now procure W-Engine Microcontroller Units through several new channels:
- The newly implemented New Eridu City Fund.
- Trading W-Engine Chips, with an exchange rate of 60 Chips for one Microcontroller Unit.
Dismantling A-Rank W-Engines at the Gadget Store or Storage will now provide W-Engine Chips corresponding to the unit’s current phase (e.g., a Phase 3 engine yields 3 Chips).
Retroactive Dismantling Credits: W-Engine Chips for A-Rank engines dismantled above Phase 1 before the 2.5 update will be distributed via in-game mail (claimable until 2025-12-31 23:59 UTC+8).

Real-World Implications:

This overhaul significantly benefits F2P and low-spending players who possess idle, upgraded A-Rank W-Engines. They can now convert these previously invested resources into future-proof materials, streamlining their inventory management and upgrade trajectories. Remember to organize your materials and claim any pending mail rewards promptly after logging in post-patch.

Initial Preparations & Day-One Directives

Upon logging in post-2.5, immediately check your in-game mail for any retroactive payouts (including S-Rank duplicate letters and Chip refunds from dismantled engines). These mail items are often time-sensitive, so claim them without delay.
Review your inventory for A-Rank W-Engines upgraded beyond Phase 1; consider dismantling them to maximize Chip returns under the new system.
Strategically plan your event shop purchases for your character builds: prioritize Microcontroller Units if you’re low, and keep future S-Rank plans in mind.
Consistently monitor banner schedules, as official announcements may differ from your local time zone.
Assess your material reserves for upcoming limited-time units or W-Engine necessities; save your Signals and premium pulls accordingly.

To Pull or Not to Pull? F2P & Banner Insights

For dedicated collectors and high spenders: The refined S-Rank duplicate system significantly enhances the value of acquiring an eighth or more copies, marginally improving account returns for those investing heavily (though this remains primarily a late-game consideration).

Guidance for F2P and low-spending players:

The Special Invitation Letter system offers long-term benefits; your primary focus should remain on banner efficiency rather than actively chasing duplicates. Aim for limited units that effectively address team deficiencies.
The W-Engine Reverberation banner presents a valuable opportunity for those needing critical engine upgrades. It is generally most efficient to save Chips and Microcontroller Units for meta-relevant engines.
If you are nearing a constellation milestone or contemplating rerolling, the updated system mitigates some historical lost value, but patience and careful planning are still paramount.

Conclusion: Strategic Advantages & Future Monitoring

Zenless Zone Zero Version 2.5 represents a thoughtful evolution in its gacha mechanics, particularly beneficial for players focused on collecting and optimizing for long-term efficiency. The enhancements to duplicate S-Rank Agent rewards and the more versatile utilization of W-Engine Chips/Microcontroller Units offer direct advantages to all player types, from F2P enthusiasts to “whales.” Furthermore, the Filmgoer Thank-You Gift serves as both an engaging premium event and a valuable catch-up mechanism for upgrading equipment without relying solely on direct pulls.
