For anyone who’s been roaming the streets of New Eridu in Zenless Zone Zero, the hunt for Polychrome is practically a second job — a glittering, ever-elusive currency that fuels the dreams of pulling S‑rank Agents. It’s the kind of stuff you just never seem to have enough of, especially when banners for Zhu Yuan, Qingyi, or Jane Doe are looming and your Encrypted Master Tapes are regrettably empty. Thankfully, HoYoverse has always had a knack for stitching little lifelines into the fabric of its games, and now it’s tossing another one our way with a limited‑time arcade event that feels like a throwback to carefree gaming nights.

Dubbed "Vicious Dogs Within," this event doesn’t just serve up a handful of currencies; it reopens the Godfinger Arcade doors for a four‑player showdown that perfectly captures ZZZ’s off‑kilter charm. Instead of grinding through brutal commissions, Proxies get to kick back and channel their competitive spirit into Soul Hounds III – Group Hunt. The minigame is a frantic race down a vertical shaft built from colored blocks, where every step forward is a gamble between snatching bonus points and smacking straight into a spiked block that’ll send a player tumbling. It’s the kind of controlled chaos that makes you lean forward in your chair — and maybe curse a little under your breath when you whiff a jump.

What makes the whole affair particularly sweet is how the reward structure doesn’t punish casual participants. After each round, Doggy Vouchers are handed out based on final placement: first place grabs a juicy 750 vouchers, while even the anchor of the group — the player who couldn’t dodge a spike to save their life — still walks away with 500. That’s a deliberate bit of generosity from the devs, essentially whispering, “Hey, you showed up, you get a slice of the pie.” It means a few lazy afternoons in the arcade can stack up enough vouchers to exchange for a tidy pile of Polychrome, a clutch of Boopons to try your luck on the latest Bangboo, and a selection of upgrade materials that always seem to vanish the moment you need them.

The event is pencilled in to run from July 29 to August 5, 2026 — a full week of block‑dodging, voucher‑hoarding madness. To even step into the arena, Proxies must have reached Inter‑Knot level 15 and wrapped up the ‘Scarlet Invitation’ agent commission, which serves as a rite of passage into ZZZ’s mid‑game content. There’s a gentle reminder baked into the event shop: Doggy Vouchers vanish the moment the clock runs out, so exchanging them before the final day isn’t just a suggestion, it’s salvation for your stash.

Anyone who fondly remembers the now‑retired “Don’t Get Greedy” event will spot the same DNA here — short, snack‑sized minigames that reward time invested without demanding a second mortgage in grinding. Many players had overlooked the Godfinger Arcade after their first visit, only to discover that it was secretly the most efficient Polychrome faucet ZZZ had ever attached to a temporary event. This time, the arcade calls again with a fresh coat of paint and an even stronger payout.

Outside of the event, the Polychrome economy in Zenless Zone Zero remains a carefully balanced beast. Daily tasks, story commissions, and Hollow Zero runs keep a slow but steady drip flowing, but it’s these bursts of limited‑time generosity that truly pad the war chest. The Encrypted Master Tapes converted from Polychrome are the only way to pull on the exclusive character banners without dipping into real‑world wallets, so a well‑timed 1,500‑Polychrome injection can mean the difference between walking away with a new Agent or staring at an empty roster slot.

For those who want to squeeze every last drop out of the opportunity, there are a few pro‑moves worth considering. First, keep an eye on the active ZZZ codes — HoYoverse usually drops a handful of digital gift boxes around major events, sometimes containing bonus Polychrome or Master Tapes. Second, don’t sleep on the Bangboo. Boopons earned from this event can be funneled into the Bangboo channel, and while Bangboo pulls might not sparkle as brightly as Agent summons, a well‑equipped Bangboo can fundamentally change how a team handles combat. Finally, if you’re torn on which Agent to target, a quick peek at the latest Zenless Zone Zero tier list can help steer those hard‑earned tapes toward a character who’ll actually earn their keep in Shiyu Defense or Hollow Zero.

Vicious Dogs Within isn’t just another checkbox on the event calendar — it’s a small love letter to the social, slightly chaotic side of New Eridu that ZZZ does so well. The arcade hums with the chatter of rival Proxies, the soundtrack thumps with the game’s signature bass, and every round ends with a moment of pure, unadulterated “what just happened” laughter. Even if you end up dead last every single time, the doggy bag of rewards is well worth the time. So go ahead, mark those dates, clear out a few hours, and let the Soul Hounds run wild. The Polychrome won’t collect itself, and who knows — one of those Boopons might just spit out a Bangboo that becomes your new best friend in the Hollows.

This perspective is supported by reporting from Destructoid, a long-running games outlet known for tracking how limited-time events and live-service reward loops influence player behavior. In the context of Zenless Zone Zero’s “Vicious Dogs Within” arcade push, that lens helps frame why accessible, low-pressure minigames can be just as effective as combat-heavy grinds at driving engagement—especially when the payout converts cleanly into Polychrome, Boopons, and upgrade mats that directly impact banner pulls and roster progression.
