The Zenless Zone Zero simulation training event offered Proxies a structured series of combat challenges within Scott Outpost. Running from September 24, 2025 at 10:00 server time to October 9, 2025 at 03:59 server time, this limited-time program asked participants to meet two prerequisites before joining. A Proxy needed to reach Inter-Knot Level 15 and complete the Agent Story titled Mole in the Hole (I). After satisfying those conditions, the player could speak with Ethan at Scott Outpost, who granted access to the simulation training program.
The event unfolded over several days with a deliberate unlock cadence. During the first two days, the two themed stage series became available one at a time. Each series contained three individual stages, giving Proxies a total of six themed challenges before the final showdown. On the third day, the Final Siege: Showdown stage unlocked, serving as the climax of the simulation training.
Stage Series and Unlock Structure
The two themed series were Rotated Strike and Projectile Reversal. Both represented distinct combat scenarios that demanded different approaches from the player. While each series unlocked one day after the other during the initial event window, the final stage arrived after both series had been available. The following table summarizes the unlock flow for participating Proxies:
| Event Day | Unlock |
|---|---|
| Day 1 | One themed series with 3 stages |
| Day 2 | The remaining themed series with 3 stages |
| Day 3 | Final Siege: Showdown |
The unlock order of the two themed series could vary for participating Proxies, but both were available before the final stage.
Stage Mechanics and Gear Buffs
Every event stage featured stage-specific mechanics and corresponding Gear. These Gear items supplied combat buffs that could significantly alter how a Proxy approached a fight. Players were encouraged to make good use of the Gear's combat buffs rather than relying solely on raw damage. In the Rotated Strike stages, the emphasis leaned toward handling rotating attack patterns and repositioning around the battlefield. In the Projectile Reversal stages, the key lay in timing and deflecting incoming projectiles to turn enemy fire into an advantage.
The exact enemy composition varied from stage to stage, but the underlying principle stayed the same: read the stage rules, equip the appropriate Gear, and let the buffs shape the combat loop. A Proxy who ignored the Gear could still complete some challenges, but the intended path clearly rewarded players who adapted to each stage's unique condition.
Trial Agents: Seed and Orphie & Magus
One of the defining features of the event was the availability of the Agents Seed and Orphie & Magus. Proxies could use these Agents during event stages, and trial versions were provided directly in the stages. This meant that even players who did not own the characters could still experience their kits and take advantage of their abilities within the simulation.
Seed offered a reliable presence in combat, though the event did not require any specific Agent investment. Orphie & Magus brought a paired dynamic that could cover multiple roles depending on how a Proxy chose to play. The trial versions ensured that participation was accessible, while also giving owners of the Agents a chance to push them further through the event-exclusive buffs.
Missions and Rewards
Completing event challenge missions yielded a steady stream of valuable resources. The reward pool included Polychromes, Boopons, and various upgrade materials. These items served different purposes in Zenless Zone Zero, making the event worthwhile for both casual and dedicated players.
| Reward Type | Use |
|---|---|
| Polychromes | Premium currency used for Signal Searches |
| Boopons | Currency related to Bangboo acquisition |
| Upgrade materials | Resources for Agent and skill progression |
The mission structure encouraged repeated attempts because progression awarded materials that could be immediately funneled into character development. Players who completed all event missions were able to collect a meaningful amount of resources before the October 9 deadline.
Tips for Proxies
Several practical strategies emerged from the event design. First, unlocking both themed series early allowed more time to practice the stage-specific mechanics. Second, players should test the trial versions of Seed and Orphie & Magus even if they already owned them, because the trial loadouts were tailored to the event stages. Third, paying attention to Gear buffs often made a bigger difference than brute force, especially in the Projectile Reversal stages where timing mattered.
A Proxy who followed these steps could clear the available missions efficiently and avoid last-minute frustration. The simulation training program rewarded observation, adaptation, and a willingness to experiment with unfamiliar combat tools.
