Once Human — Scenario Endgame Guide

2026-08-12

Big picture first: a lot of what you'd find in guides is now wrong. Two 2026 patches rewrote the progression math, and they change the answer to almost everything you asked.

The thing that actually matters now: Starchrom

As of the March 25, 2026 update (v2.3.5), the Blueprint Shop and Stellar Stairway were retired and blueprints are now activated directly with Starchrom — no fragment collection in between. (Soren) Exploration points, crates, settlement treasures, first-clear dungeon rewards, and tasks that used to give blueprint fragments now award Starchrom directly. (Once Human)

So the permanent value of this scenario is: Starchrom harvested, converted into blueprint unlocks/star levels that follow you forever. Everything else — your level, tech tree, base, gear, stardust stockpile — is rented.

One catch: there's a monthly Starchrom cap, visible on the Blueprint screen. Starchrom from events, Battle Pass, and Collection Level doesn't count toward it. (Once Human) Check where you stand before you grind — if you're capped, redirect effort.

Welding machine / Stardust — worth it, but know what you're buying

Welding Machines are junk loot that disassemble into 9 Metal Scraps, 3 Adhesive, and 12 Special Parts. (Fandom) You want one because the Stardust-Powered Electric Furnace recipe needs 1 Welding Machine (alongside 100 Stardust Ore, 75 Gold Ore, 15 RaidZone Chips, a Power Cable, etc.). The Recycling Electric Furnace also needs one.

Where they spawn: Chalk Peak and Red Sands, on junk items scattered around high-level areas — worth going in only when geared, since those regions swarm with high-level enemies. (Game8) Players also report Blackfell Oilfields (inside the blue containers) and the 73 Source Extraction Zone as reliable spots for both welding machines and the furnaces themselves.

The shortcut nobody mentions: if you find a Stardust-Powered Electric Furnace already placed in the world, you can pick it up and place it in your territory — no welding machine, no crafting. Players specifically call this out as the way around the welding-machine bottleneck. Reverse-engineering one instead consumes the find but gives you the tech; and repeating reverse engineering on the same facility yields Tech points. (Once Human)

Honest ROI check: Stardust Source's primary use is calibrating weapons and armor at the Gear Workbench. (Fandom) That's real power — but Tech Levels reset at the end of a scenario, (Once Human) and the furnace doesn't come with you. With ~2 weeks of phases plus a settlement phase left, you're building an engine you'll run for maybe 5–6 weeks. It's worth it if you're going to play out settlement hard; it's not worth derailing region unlocks for.

What survives vs. what dies

• Survives: Starchrom, Mitsuko's Marks, Sproutlets, blueprints and their star levels, cosmetics, furniture formulas, house designs, friends list, Battle Pass progress.
• Dies: character level, tech tree, map discovery, territory.
• Goes to Eternaland Depot: materials, weapons, deviations — you spend Transfer/Resource Points to pull some back in next scenario.

The critical 2026 change: gear brought in from Eternaland is now automatically marked "lost gear." It can't be repaired, reverse engineered, or traded, and the All-Purpose Hand can't repair it inside a scenario either. (Once Human) That guts the old "stockpile a killer arsenal for next season" strategy. Imported gear is now a disposable starter kit that degrades to nothing.

So: should you prep Eternaland?

Mostly no. Low priority. What's actually worth doing before the server closes:

• Bank materials and Deviations, not gear (gear is the thing that got nerfed).
• Watch for anything in territory storage flagged with red "destroyed at end of Season" text.
• Deposit into the Account Depot early rather than waiting — items not settled during Scenario Settlement can't be moved to the Account Depot afterward. (Once Human)
• Don't leave loose items outside your inventory when you transfer; there's a long history of things vanishing.
• Terraforming was added to Eternaland in April 2026 if you enjoy the building side, but that's a hobby, not progression.

Main quest: yes — but as a key, not a story

Push it, because region unlocks are what gate the Starchrom-bearing content: Rift Anchors, Monoliths, Securement Silos, Mystical Crates. Level 34 heading into the end of Phase 4 is behind the curve, and being underleveled is exactly what's keeping you out of Chalk Peak and Red Sands — where your welding machines are. Catch-up leveling and main quest are the same task.

Priority checklist for the time you have left

Roughly in order of Starchrom-per-hour:

1. Mystical Crates — one-time per scenario group, now pay Starchrom. Use mapgenie's Nalcott map and sweep every settlement you've unlocked. This is the single biggest one-time pool.
2. Scenic viewpoints / exploration points — cheap, fast, one-time each.
3. First-clear rewards — every Securement Silo and Monolith you haven't cleared.
4. Prime War frontiers — 800–1,000 Starchrom per Frontier on first clear, with more difficulties opening as phases progress. (Game8)
5. Territory Purification — up to 40 Cortexes per week through a Stardust Resonant Filter. (Game8) Build the filter if you don't have it.
6. Stellar Planula → Severin — Starchrom Crates at 500 each for 100 Planula, capped at 8 per season for 4,000 total. (Game8) Farm Morphic Crates for the Planula.
7. Hoard Energy Links now. In the final phase you can buy Starchrom Crates from the Seasons Shop with Energy Links — 10,000 for the first, escalating from there. (Game8)

End-of-scenario: your four actual options

1. Ride it out. For Manibus, the Settlement Phase lasts 4 weeks; afterward the server closes and your character and applicable items go to Eternaland. (Game8) That's a long tail — plenty of time to run silos, sweep crates, and use that Stardust furnace.
2. Let it go permanent. Servers that reach the settlement phase are converted into non-shutdown "permanent scenario servers" — one phase only, which never ends, with character data (level, scenario resources, cosmetics, achievements) merged in automatically. You keep playing the same scenario at your own pace instead of switching. (Once Human) The tradeoffs: Worlds get merged over time based on active population, and after a merge your territory may be recalled to avoid location conflicts. (Once Human)
   Worth verifying in-game whether Novice servers get this treatment — the official announcement named Manibus, Evolution's Call, Prismverse's Clash, and Way of Winter, and Novice is a separate difficulty tier that you can only play once. Your scenario panel will tell you.
3. Sign up for a new scenario. Standard route, free, available once you hit the final phase.
4. Early exit. A Scenario Exit Card sends you to Eternaland where you can sign up for a new scenario, but it effectively ends your progress on the original one and you can't return to that server. (Steam Community) Only pull this lever for friend-sync reasons.
5. Park. Do nothing — sit in Eternaland indefinitely until you sign up. Free, and it's your best synchronization tool.

Syncing with your friends — the practical play

The core problem is that you can only sign up for a new scenario once your server reaches its final phase, and your friends are on different clocks. Three mechanisms help:

1. Invite codes. Players already on a server can find a special invitation code on their Player Info screen and share it; friends can use it to enter even when the server is full. Each player can invite up to five friends. (Steam Community) Do this early — server caps still apply.
2. Parking. Whoever hits settlement first sits in Eternaland at zero cost and waits for the stragglers. This is almost always better than burning an Exit Card.
3. Worlds, not just servers. Same server isn't enough — servers contain multiple Worlds, and you need to be in the same one. Switch at a teleportation antenna.

The timing hook worth planning around: Once Human launches on PS5 and Xbox on August 25, 2026 with full crossplay. (NetEase Games) Expect a wave of fresh servers and a large influx of new players. That's a natural rally date — pick a scenario, agree on a launch window, and everyone converges on a brand-new server rather than trying to squeeze into an established one.

Which scenario next?

Current PvE: Manibus (Normal, Hard), The Way of Winter, Endless Dream, and Deviation: Survive, Capture, Preserve. Current PvP: Evolution's Call, Prismverse's Clash, Isles of the Abyss, and RaidZone. (Fandom) Isles of the Abyss is the newest — ocean and island survival with ships, underwater resources, and an 8-player Sunken Lord dungeon — but it's tagged PvP.

For permanent progression, the strongest pick is a scenario you've never played, because one-time crate pools reset per group. One community note worth knowing: Novice counts as one group, and Manibus, Prismverse's Clash, and Evolution's Call on Southern Nalcott share crate progress with each other. (Paradoxgaming) That points at Way of Winter or Endless Dream as fresh crate territory — different map, untouched Starchrom.

What I'd de-prioritize

• Perfecting the base build (dies with the server)
• Tech tree investment beyond what unlocks Starchrom-bearing content (resets)
• Stockpiling gear for Eternaland (now "lost gear")
• Hoarding raw materials past what Transfer Points will actually carry

One last note on stale guides

The April 8, 2026 patch removed the Specialization system entirely, folded it into Tech tree nodes, dropped level requirements from gear, and consolidated rifle/SMG/LMG ammo into a single medium-caliber standard, along with merging fabrics, parts, and plastics into unified types. (XP Gained) Any guide that tells you to unlock "Oil Processing Memetic Specialization" for Stardust Source is describing a system that no longer exists — that path now runs through the Tech tree and reverse engineering.
