Version 2.5, “To Be Fuel for the Night,” lands in Zenless Zone Zero on December 30 and arrives with a dense set of giveaways, login incentives, and a high‑end spending campaign. The headline items are a free limited S‑Rank agent, a free swimsuit outfit, and a one‑time top‑up event that lets heavy spenders pick an S‑Rank agent and W‑Engine from a small pool.
Free rewards in Zenless Zone Zero version 2.5
The easiest wins in 2.5 are tied to simply logging in around the update window.
Free S‑Rank Zhao. Every account can invite the new S‑Rank Ice Defense agent Zhao to their roster at no cost during the version. There is no gacha requirement; logging in and following the in‑game prompts during 2.5 is enough to claim her and a bundle of materials that can push one agent to level 40. Zhao specializes in Ice Defense and uses Frostbite stacks to trigger Ether Veil: Wellspring, a state that buffs the entire squad’s performance.
Jane Doe swimsuit outfit. Jane gets a new swimsuit skin in 2.5, and it is being distributed for free during the version. You obtain it through the Today’s Outfit section of the in‑game Store at a 100% discount, so it still goes through the usual cosmetic purchase flow, but without a currency cost as long as you claim it in time.
1,000 Polychromes celebration gift. To celebrate Zenless Zone Zero winning a PlayStation Partner Awards 2025 Grand Award, every player can receive a one‑time grant of 1,000 Polychromes by logging into the game on or after January 1 at 12:00 (UTC+8) and checking in‑game mail. This sits on top of the other 2.5 rewards and can be used on any banners you want.
Version login Polychromes. On top of the celebration grant, there is a small version‑specific login bonus: 160 Polychromes are given for logging in after the 2.5 update. When paired with the pre‑registration campaign (covered below), that adds another 320 Polychromes to your balance with minimal effort.
2.5 sign‑in event: 10 limited pulls and 10 Boopons
Version 2.5 continues the pattern of in‑game check‑in events that hand out pulls over several days.
In‑game 7‑day check‑in. The “Coronation of the Void Hunter” in‑game sign‑in event grants a total of Polychrome ×480 for logging in over seven days during the patch. That sits alongside a more traditional login campaign that hands out gacha items directly: Encrypted Master Tape ×10 and Boopon ×10 over the duration of the event period, assuming you log in enough days to hit all the milestones.
HoYoLAB daily check‑in bonus. The existing web check‑in system for Zenless Zone Zero on HoYoLAB continues in 2.5. Linking your HoYoLAB account and checking in there adds an extra Polychrome ×30 bonus on top of the in‑game rewards for new users. To use this flow, you sign in via the dedicated ZZZ check‑in page on HoYoLAB at act.hoyolab.com/bbs/event/signin/zzz/e202406031448091.html and then claim your rewards from in‑game mail.
Pre‑registration bonuses for version 2.5
Even though the game is long since launched, the 2.5 cycle brings its own pre‑registration campaign themed around the Void Hunter.
Website pre‑registration. By pre‑registering for version 2.5 on the dedicated event website, you receive Polychrome ×320, the in‑game commemorative item “Letter from Xiao’Guang,” and the “Walker of Light” title. These arrive via in‑game mail once the version is live and you’ve linked the same account.
In‑game “Coronation of the Void Hunter” check‑in. The in‑game side of this campaign grants Polychrome ×480 for logging in across seven days during the event window. Combined with the web pre‑registration, that’s 800 Polychromes attached to the Void Hunter theme alone, before counting the separate 160+160 version login bonuses and the 1,000‑Polychrome PlayStation award gift.
Event raffle. The pre‑registration page also hosts a lucky draw that can roll out physical rewards like an iPhone, game consoles, figures, and additional Polychrome bundles. Entry for the draw is handled on the event site; winners receive instructions there rather than in‑game.
2.5 livestream code and how to redeem it
Version 2.5 ships with a single livestream gift code. It has a short expiration window, so it is only relevant for players who act quickly around the program date.
| Code | Rewards | Expires |
|---|---|---|
VOIDHUNTER1230 |
Polychrome ×300, Senior Investigator Log ×2, W‑Engine Energy Module ×3, Denny ×30,000 | December 20, 2025, 11:59 (UTC+8) |
Once the deadline passes, the code no longer works, so treat this as a limited‑time bonus rather than a persistent source of pulls.
How to redeem Zenless Zone Zero gift codes
There are two supported ways to redeem ZZZ codes: through a web browser and inside the game client. Both methods send rewards to your in‑game mail once the code is accepted.
Method 1: redeem codes in a browser
Step 1: Open the official Zenless Zone Zero code redemption page at zenless.hoyoverse.com/redemption in any browser.
Step 2: Sign in with the same HoYoverse account you use on your game client so the rewards can be delivered to the right server and character.
Step 3: Select your game region from the dropdown, then paste or type the code (for example VOIDHUNTER1230) into the field and confirm the redemption.
Step 4: Launch the game, open the “More” tab, go to the Mail section, and claim the attached items.
Method 2: redeem codes from inside the game
Step 1: From the main screen, open the menu and move to the “More” tab.
Step 2: Select the “Redemption Code” option. This opens an input box specifically for gift codes.
Step 3: Enter the code exactly as shown and confirm. A success message indicates that the code has been applied to your account.
Step 4: Go back to “More”, open Mail, and accept the rewards to move them into your inventory.
Note: Codes are generally one‑time per account and can be region‑locked or time‑limited, so a valid redemption on one server does not guarantee the same code will function on another.
“Filmgoer Thank‑You Gift” top‑up event: what it is and what it isn’t
The most divisive element of 2.5 is the “Filmgoer Thank‑You Gift” campaign. It sits visually alongside the free rewards in promotional material but is structurally different: it is a spending event tied to real‑money top‑ups, not a free login bonus.
How the event works. During the campaign window, every purchase of Monochrome (premium currency), Battle Pass, or Inter‑Knot membership contributes toward cumulative top‑up milestones. Hitting specific currency thresholds unlocks tiers of rewards. At the top tiers, you can pick one S‑Rank agent and one S‑Rank W‑Engine from a pool of nine options.
The S‑Rank agent pool prominently includes limited characters like Jane Doe, Burnice, and Qingyi, alongside standard‑banner agents. The W‑Engine pool mirrors that structure with their associated best‑in‑slot weapons. These are direct selections, not additional gacha pulls, but they only unlock once the relevant spending threshold is reached.
Not retroactive and not free. The structure mirrors similar “spend to earn” events used in other HoYoverse games. Purchases made before the event window do not typically count toward the milestones, and there is no way to engage with the selector without topping up during the campaign. If you usually play free‑to‑play or spend lightly, treat this as optional whale‑targeted content rather than part of the baseline rewards package.
Best use cases. The value proposition skews toward players who were already planning to spend heavily in 2.5 or across upcoming patches and can treat the selectors as a bonus on top of their Monochrome purchases. For those players, the event is a way to secure a targeted S‑Rank agent and W‑Engine that otherwise rely on luck and pity.
Gameplay events and long‑term rewards in 2.5
Beyond pure currency and cosmetics, version 2.5 ties several substantial rewards to limited‑time gameplay modes and structural changes to existing content.
Joint Investigation: The Divine Maze. This is the long‑awaited multiplayer co‑op mode. Three‑player squads enter fast‑paced combat scenarios that reward coordination and timing. The event runs for a limited period inside the patch and hands out materials and other resources for clear rewards, though exact drop tables are handled in‑game.
Sword Seeker Chronicles and Ye Shunguang trials. The main story chapter “To Be Fuel for the Night” caps Season 2’s Waifei Peninsula arc and leads into the Sword Seeker Chronicles epilogue, which focuses on Ye Shunguang’s struggle with the Qingming Sword backlash. Playing through these quests and side events showcases Ye Shunguang’s Bladeflash Mirage ability and unlocks an exclusive new W‑Engine linked to her kit.
Shiyu Defense and Deadly Assault updates. Shiyu Defense is being rebuilt into three‑team content with five stages and improved rewards, pushing more value into high‑end combat play. Deadly Assault also receives adjustments. These modes are long‑tail sources of upgrade materials and long‑term account power, so their reward tuning has a direct impact on how quickly squads can progress.
Proxy Outpost and long‑term buffs. The new Proxy Outpost feature functions as an in‑game community hub, letting players form or join “outposts” centered around interests and share commissions. In parallel, a slate of older agents is being systematically buffed. In 2.5, Soldier 0 – Anby, Ellen, Soldier 11, Grace, and Burnice receive updated mechanics and performance boosts, with a plan to extend similar treatment to all agents in the permanent Stable Channel over time. For anyone sitting on copies of these characters, this is effectively a free power upgrade.
Combat Simulation quick‑sweep. A new sweep mechanic lets you spend Ether Batteries to instantly clear eligible Combat Simulation stages and grab promotion materials and Drive Discs. That converts what used to be a time‑consuming grind into a quick energy sink, freeing up more of each play session for story content, Shiyu Defense, or co‑op.
Taken together, version 2.5 is generous if you only care about free value: Zhao, a full outfit for Jane, several hundred Polychromes through logins and pre‑registration, and a burst of 1,000 Polychromes tied to the PlayStation award celebration. The “Filmgoer Thank‑You Gift” top‑up event sits in a different category, offering targeted high‑end rewards for those willing to spend heavily during the patch. The cleanest way to approach the update is to treat everything Zhao‑related, the skin, and the login currency as baseline, and decide separately whether the paid selector path matches how you already play and spend.
