How I Finally Tamed the Zeno-Purifier in Once Human (And You Can Too!)
Once Human Zeno-Purifier Deviant guide: unlock this powerful battlefield companion by defeating 200 enemies with melee weapons.
Let me set the scene for you: it’s 2026, and the Stardust-apocalypse is still going strong in Once Human. I’m knee-deep in mutated horrors, my rifle just jammed (classic), and a group of Deviations is sprinting toward me with bad intentions. That’s when I remembered—I still hadn’t unlocked the
Zeno-Purifier Deviant. My friends kept telling me it was a game-changer, a floating companion that deletes enemies while you sip coffee in your territory. But getting it? Oh, that was a journey worthy of a post-apocalyptic memoir.
If you’re new to the wasteland, Deviations are essentially Stardust-mutated creatures that you can capture and turn into useful little (or not so little) buddies. Some sit pretty in your base, boosting crafting speeds; others, like the Zeno-Purifier, join you in the field and deal damage like a loyal, angry Roomba. I wanted that angry Roomba badly. So I rolled up my sleeves, consulted the in-game menus like a true meta-human detective, and found the quest.
Getting the Zeno-Purifier Deviant isn’t about hunting a rare spawn or clearing a dungeon. Nope. It’s locked behind a Season Goal—a challenge so deceptively simple that I almost cried when I first read it. You just have to defeat 200 enemies using a melee weapon. Just 200. With a melee weapon. In a game where everything either spits acid, flies, or explodes. 😅
Here’s exactly how to find the goal, because the UI in Once Human is busier than a downtown market on discount day:
-
Press
Escto bring up the main menu. -
Look for the season banner in the upper-right corner—it’s the flashy one that screams “LOOK AT ME.”
-
Navigate to the Season Goals tab.
-
Select the ‘Of Mist And Mirage’ phase rewards banner (seriously, the names get poetic).
-
Head into the Challenges tab, scroll all the way down, and there it is, the final goal, staring at you with its melee requirement.
Now, I’m a sniper at heart. Running at enemies with a glorified stick felt like betrayal. But for that Deviant? I grabbed a reinforced baseball bat and turned into a one-man blender. I lost count of how many times I got swarmed, but the satisfaction of that final kill—number 200—was euphoric. The Zeno-Purifier Deviant dropped into my inventory as a reward, and I’m pretty sure a single tear rolled down my stardust-covered cheek.
But wait, the saga doesn’t end at acquisition. The Zeno-Purifier is a bit of a diva. You can’t just shove it in a backpack and call it a day. You need to store it in an Isolated Securement Facility back at your territory—think of it as a creature apartment with very specific rent demands. Once it’s safely tucked away, sync it to your cradle, and you can equip it as a Deviant companion.
Now comes the fun part: battlefield summoning. When you’re in combat, hold ‘E’ and a radial menu pops up, letting you select the type of attack you want your floating pal to perform. The Zeno-Purifier isn’t just a passive damage dealer—you get tactical choices. Want it to focus on a priority target? Send it. Need area suppression? There’s likely an option. (Okay, I mostly mash buttons, but the tooltips exist.)
The deviant’s energy drains as it fights, though, and nobody wants a lazy sidekick that naps mid-siege. To keep its energy restoration fast and its mood high, I learned two tricks from veteran survivors:
-
❤️ Put it under red light. For reasons known only to the Stardust gods, red lighting makes the Zeno-Purifier feel cozy.
-
🎵 Play music nearby. I placed a jukebox right next to the containment unit. It might love post-apocalyptic rock, or maybe it’s just a sucker for ambient beats—either way, it recharges like a champ.
In battle, the Zeno-Purifier is everything I hoped for. It hovers around, looking simultaneously adorable and menacing, and zaps creatures while I frantically dodge roll. Its attacks directly deal damage to the enemies you’re facing, which means you can finally focus on survival instead of chipping away at bullet sponges. I’ve used it against everything from basic shamblers to tough elite monsters, and it consistently turns sweaty fights into leisurely afternoon strolls (okay, slightly tense power walks).
The only downside? Remembering to summon it. I’ve lost count of how many times I’ve died, only to realize mid-death animation that I hadn’t pressed ‘E’. Old habits, man.
So, is the Zeno-Purifier worth the grind of bopping 200 heads? Absolutely. It’s one of those Deviants that genuinely shifts how you approach combat, making the polluted world of Once Human feel just a little less terrifying. Plus, you get an insane amount of melee weapon experience, so silver linings.
Now, if you’ll excuse me, my Purifier is fully charged, my baseball bat is dented beyond recognition, and there’s a glowing anomaly on the horizon that looks like it needs a good zapping. Happy hunting, fellow meta-humans. May your red lights be bright and your playlists be fire.
🎮 Pro tip: If you’re reading this in 2026 and the Season Goals have rotated, similar Deviants often hide behind combat challenges. Check the latest phase rewards and start swinging.
