Once Human Lost in Madness: Introduction to the Quest
Lost In Madness Quest
Lost in Madness is a haunting questline in Once Human that plunges players into a twisted reality warped by cosmic horrors. As you follow scattered clues and face off against nightmarish Deviants, you’ll uncover the disturbing truth behind a mysterious anomaly. Blending psychological tension with intense combat, this quest tests both your survival instincts and your grip on reality.

The Lost in Madness quest in Once Human starts off innocently enough—just another eerie convenience store with cultist vibes and flickering lights. But don’t let the low-level tag fool you. Listed as level 7, this side quest quickly veers into survival horror territory as you follow a cryptic Cultist’s Treasure Map across the island. No quest markers, no breadcrumbs—just you, your instincts, and the creeping sense that you’re being watched.
The biggest curveball? This “easy” mission will eventually drop you into a high-threat level 32+ zone. That’s right: what begins as a scavenger hunt ends with you dodging enemies that can one-shot unprepared explorers. The Cultist’s map doesn’t hold your hand either. It’s vague, with faded landmarks and misleading sketches that make it feel more like an ARG than a side mission. If you’re here for XP and easy loot, this quest might chew you up.

That said, the Once Human Lost in Madness guide wouldn’t be complete without a tip: treat this quest like a long game. Prepare before diving deep. Bring a sturdy vehicle, solid weapons, and enough food to camp in hostile zones. If you treat it like a low-tier task, you’ll end up respawning a lot more than you’d like. But if you take it seriously, it’s one of the most rewarding—and weirdly atmospheric—side quests in the game.
Once Human Lost in Madness: Starting the Quest

To kick off the Lost in Madness quest, you’ll need to head to Coastside Plaza in the Dayton Wetlands. Look for a rundown shop called BNMart (or BN Store, depending on your map version). It’s sitting on the eastern coastline like it’s got better things to do. Inside, it’s full of the usual cult décor—symbols on the walls, melted candles, and the kind of ambiance that says “something cursed happened here.” You’ll want to be at least level 7, but don’t let your guard down. Even the starter enemies can hit harder than expected.
The red candle in the corner is your trigger. Interact with it, and reality gets weird for a moment—your screen will blur, sounds may warp, and suddenly a chest appears. It might spawn right in front of you or just off to your right. Open that chest, and you’ve officially stepped into the madness. Inside is the Cultist’s Treasure Map, and with it, the quest begins. No flashy quest markers, just a piece of paper and a bad feeling in your gut.
