Zenless Zone Zero Version 2.2 Complete Event Calendar Overview
Major Event Timeline
Here’s the deal: Version 2.2 kicks off September 4, 2025, at 11:00 AM (UTC+8) following what’ll probably feel like the longest five-hour maintenance ever. If you’re Inter-Knot Level 4 or higher—and let’s be real, who isn’t by now?—you’ll snag 300 Polychromes as compensation. The version runs until mid-October (14th-15th), giving us a solid six weeks to work with.
Now, the dual login campaigns are where things get interesting. The All-New Program runs the entire patch duration (September 4 - October 14) and hands out 10 Encrypted Master Tapes just for showing up daily. Then there’s ‘En-Nah’ Into Your Lap starting September 24—another 10 Boopons waiting for you.
The event lineup? Pretty solid. Band of Brave Bangboo launches September 5 with tower defense mechanics (because apparently every game needs tower defense now) but hey, free A-Rank Bangboo Excaliboo makes it worth your time. Floral Voyage Into the Unknown times perfectly with Seed’s banner launch—no coincidence there. Rhythm Rave wraps up the patch from September 29 through October 13 with exclusive namecards.
For players considering Zenless Zone Zero Top Up to supplement those free resources, BitTopup’s got competitive rates with instant delivery. Sometimes you just need that guarantee, you know?
Weekly Rotation Schedule
Shiyu Defense cycles through three distinct buff phases—each lasting about two weeks. Phase I brings Electric/Physical damage +30% with Attribute Anomaly damage +30%. Squad ATK jumps 10% or 25% depending on whether you’re running one or two Attack agents. Phase II gets spicy: Attack agents ignore 10-20% enemy DEF, plus you get +60% CRIT DMG for 10 seconds after triggering Aftershock. Phase III mixes things up with Electric/Fire damage +15%, Sheer damage +20%, and a hefty +80% CRIT DMG lasting 15 seconds for Attack/Rupture agents.
Deadly Assault rotates boss lineups too. Phase I throws The Defiler, Miasmic Fiend - Unfathomable, and Miasma Priest at you. Phase II switches to The Defiler, Notorious - Dead End Butcher, and Notorious - Pompey. Phase III? More Miasmic enemies with Unknown Corruption Complex additions—because apparently we needed more corruption in our lives.
Ridu Weekly resets every Monday with that grid-based quest system. You’re aiming for 1,300 points, which nets you alternating 15 Polychrome rewards and materials at each milestone.
Daily Reset Timings
Everything resets at server time (UTC+8)—mark your calendars. Four core Errands drop 60 Polychromes daily: logging in (easiest money ever), grabbing coffee at Coff Coffee, using scratch cards, and managing that video store. Just make sure you’ve cleared Explosive Last Train in the main story first.
That coffee isn’t just for show either—it restores 60 Battery Charge daily plus HIA training bonuses. Trust Events let you interact with three agents daily (because friendship is magic, apparently). The Video Store? Pure passive Dennies without lifting a finger.
Limited-Time Content Alerts
Double-drop events are your best friends here. Advanced Bounty: Routine Cleanup (September 18-23) doubles Drive Disc rewards for the new Dawn’s Bloom and Moonlight Lullaby sets. Data Bounty: Combat Simulation (October 9-14) maxes out character ascension materials—perfect timing for those last-minute builds.
Oh, and that main story chapter An Incomplete Story? The door code puzzle solution is 3752. Boom. 60 Polychromes and materials just for remembering four digits.
Resin-Free Daily Activities: Maximum Efficiency Guide
Coffee Shop Visits Strategy
Coff Coffee visits offer the best value-to-time ratio in the game, hands down. One daily coffee restores 60 Battery Charge—that’s three hours of natural regeneration in one sip. Time it right before major farming sessions, especially during double-drop events. The restoration stacks with natural regen too, so you can temporarily break that 240 Battery cap.
Video Store Rental Optimization
The Video Store is basically free money with extra steps. It accumulates Dennies automatically—you just need to collect periodically to keep rates optimal. Takes under a minute daily while checking off that Errand completion. Can’t argue with passive income.
Scratch Card Collection Routes
Scratch cards spawn predictably across New Eridu daily. Smart routing from the coffee shop through central areas gets you done in two minutes flat. Sure, the cards themselves aren’t game-changing, but that Errand contribution adds up.
Commission Board Priorities
Daily commissions need 10-15 minutes for substantial Polychrome contributions. Combat-based ones finish faster than exploration objectives—learned that the hard way. Commission completion feeds into weekly progression too, so it’s more valuable than the immediate rewards suggest.
Weekly Rotation Schedule & Reset Timings
Shiyu Defense Rotation Calendar
Three phases spanning Version 2.2’s duration. Phase I (first two weeks) favors Disorder teams with that Electric/Physical and Attribute Anomaly boost. Phase II creates burst windows—Attack agents ignoring DEF plus +60% CRIT DMG after Aftershock makes for some satisfying damage spikes. Phase III offers more flexibility with Electric/Fire damage buffs and extended CRIT windows for varied rotations.
Hollow Zero Weekly Changes
Research Point weekly limits pair with rotating Bounty Commissions. Combat-focused ones complete faster than exploration objectives (sensing a pattern here?). The Research Point economy really encourages consistent weekly participation over those marathon sessions.
Combat Simulation Schedules
Material availability rotates based on character ascension needs. Shock Chips for Electric agents appear on specific weekdays—keep track if you’re building someone like Anby or Anton. That double-drop event October 9-14? Prime farming period. Start saving Battery now.
Weekly Mission Refresh Times
Monday server reset for everything weekly. Ridu Weekly needs strategic grid completion for those 1,300 points. Notorious Hunt gives three free weekly claims, then costs 60 Battery each after that. Plan accordingly.
Free Pull Sources & Polychrome Farming Routes
Daily Free Pull Opportunities
F2P players looking at roughly 90 pulls over six weeks—not terrible for a gacha game. Daily Errands contribute 2,520 Polychromes (21 pulls) over 42 days through four tasks taking under 10 minutes. Trust Events add resources through daily agent interactions. It’s all about consistency.
Weekly Polychrome Income
Let’s break down the weekly haul: Ridu Weekly drops 105 Polychromes weekly (630 total). Shiyu Defense offers 360 weekly through floor completion. Deadly Assault contributes 150 weekly via boss challenges. Hollow Zero provides roughly 160 weekly through Research Points and Bounty Commissions. Combined weekly total? Around 775 Polychromes—that’s 6.5 pulls per week.
Event-Based Pull Rewards
Those dual login campaigns contribute 20 total pulls (10 Encrypted Master Tapes plus 10 Boopons). Band of Brave Bangboo provides approximately 1,000 Polychromes through tower defense completion. Story content rewards 60 Polychromes per major quest—not huge individually, but it adds up.
When planning pulls, consider Buy ZZZ Polychrome through BitTopup for instant delivery when free resources fall short of pity requirements. Sometimes you just need that guarantee.
Hidden Achievement Pulls
Version 2.2 introduces achievements tied to story completion, character interactions, and gameplay mechanics. Combat achievements complete through regular progression—no extra effort required. Exploration achievements reward thorough investigation of new areas. Free Polychromes for being curious? Yes, please.
Critical Don’t-Miss Quests & Time-Sensitive Content

Weekly Must-Complete Missions
Ridu Weekly progression to 1,300 points ensures maximum Polychrome acquisition. Shiyu Defense full clear provides 360 weekly Polychromes—that’s nearly three pulls right there.

Limited-Time Event Quests
Band of Brave Bangboo (September 5 - October 13) offers free A-Rank Bangboo Excaliboo through tower defense.

Expiring Reward Deadlines
Double-drop windows are non-negotiable: September 18-23 for Drive Discs, October 9-14 for Combat Simulation materials. Login campaigns require daily participation for those 20 total pulls—miss a day, lose rewards. Redeem codes like ALICEYUZUHA (50 Polychromes) and ZZZ21SUMMER (60 Polychromes) have varying expiration dates, so use them quickly.
Optimal Daily Routine Planning for Version 2.2
Morning Login Checklist
Start with coffee consumption for Battery restoration and HIA bonuses. Grab scratch cards during your New Eridu traversal—two-minute route, maximum efficiency. Video Store management integrates naturally with other activities. Check that Ridu Weekly grid for daily tasks aligned with your planned activities.
Peak Hours Activity Schedule

Evening Wrap-up Tasks
Trust Event interactions with three agents—don’t forget this one. Final Errand verification prevents missed daily Polychromes (painful lesson learned). Battery spending optimization before daily reset. Daily login reward collection and mailbox checking.
Weekend Intensive Sessions

Resource Management: Resin vs Resin-Free Comparison
Battery Efficiency Analysis
Combat Simulation runs 20-100 Battery per attempt for guaranteed ascension materials. Drive Disc farming costs 40 Battery per run with variable quality—RNG can be brutal. Notorious Hunt charges 60 Battery per additional claim beyond three weekly freebies. Weekly Battery regeneration totals 1,680 units.
Resin-Free Reward Values
Daily Errands deliver 420 Polychromes weekly without touching Battery—pure profit. Ridu Weekly provides roughly 105 Polychromes weekly through grid completion. Trust Events offer incremental but consistent progression. Exploration and achievements give one-time Polychrome rewards with permanent value.
Priority Activity Rankings
Here’s the hierarchy—in my experience:
Daily Errands (guaranteed 60 Polychromes, minimal time investment)
Weekly activities (Shiyu Defense, Deadly Assault, Ridu Weekly)
Event participation (based on value-to-effort ratios)
Battery activities (based on current progression needs)
Cost-Benefit Calculations
