Once Human Redeem Codes for April 2026: Free Starchrom and More

Two free pulls at the Wish Machine are sitting unclaimed right now, and most Once Human players haven't touched them yet. The codes 2026SFOH and S3STREAMER each deliver 1,000 Starchrom, the game's premium gacha currency, on top of a Butterfly's Emissary Crate II and a [100 off 500] shop coupon apiece. Combined, that's 2,000 Starchrom from two quick copy-paste jobs. In a game where a ten-draw costs 10,000 Starchrom, every free pull chips away at a grind that can otherwise take weeks of daily login bonuses to build.

Claim these two first. No expiry date has been confirmed by Starry Studio, but codes distributed via streamer and seasonal promotions have a history of disappearing without warning.

Active Codes: Claim These Now

The two highest-priority codes both deliver identical bundles, which is unusual but welcome:

• 2026SFOH: 1,000 Starchrom + Butterfly's Emissary Crate II + [100 off 500] Shop Coupon
• S3STREAMER: 1,000 Starchrom + Butterfly's Emissary Crate II + [100 off 500] Shop Coupon

Both were confirmed active as of the Pocket Gamer April 5 update. No hard expiry has been published, but given that streamer-tied codes typically run on limited redemption pools rather than calendar deadlines, these can go dark at any point once the use cap is hit.

A third code, STARLIGHTOH, was also listed as active but appears to be tied to a seasonal event window and may be in a limbo state depending on your region and server. Try it, but don't bank on it.

Creator and Event Codes: Likely Expired, But Worth a Shot

A batch of creator-promotion codes distributed across YouTube, Twitch, and TikTok channels offered combo gift boxes and Paradise Coins:

• CC1030YOUTUBE: Nutcracker Combo Gift Box + 50 Paradise Coins
• CC1030TWITCH: Faded Wings Combo Gift Box + 50 Paradise Coins
• CC1030TIKTOK: Starry Dream Combo Gift Box + 50 Paradise Coins
• 1030OHPALS: 100 Paradise Coins + 1x Butterfly Emissary Crate + [100 off 500] Shop Coupon
• OHPALCROSSW: Nutcracker Combo Gift Box + 100 Paradise Coins

These were active during a cross-platform creator push but have since been marked expired on multiple tracking sites. They're included here because redemption is instantaneous and costless, so attempting a dead code costs nothing except fifteen seconds. If the system accepts one, count it as a bonus.

What Starchrom Actually Does (And Why This Matters)

Starchrom is the fuel for Once Human's Wish Machine, the gacha-style system where players spend currency in exchange for randomized high-tier gear and blueprint fragments from Mr. Wish, the game's cryptic merchant character. You can pull individually or in groups of ten, with ten-draws offering the typical pity-track advantage most gacha players will recognize. Specific weapon blueprints and rare equipment don't drop from the open world reliably enough to skip the Wish Machine entirely, which means Starchrom from redeem codes isn't just a nice bonus. It's a direct substitute for real money spent on premium currency.

Activators, the other commonly distributed reward in these code drops, function as consumable boosters, roughly analogous to potions that amplify progression during active play sessions. They're worth holding rather than using immediately, since their value scales with how much content you're pushing through at any given time.

How to Redeem Codes: Mobile and PC

The redemption path differs slightly between platforms, which trips up a lot of players switching from PC to mobile.

On mobile (iOS/Android): 1. Open the main menu 2. Tap Settings 3. Select Redeem Code 4. Enter the code and confirm

On PC: 1. Press F3 in-game (or navigate from the main menu to Shop Events) 2. Select Redeem Code from the bottom of the Shop Events screen 3. Enter the code exactly as written and confirm

Rewards land in your backpack immediately after a successful redemption.

Common Failure Fixes

Codes not working almost always come down to one of three issues:

• Case sensitivity: Once Human codes are case-sensitive. STARLIGHTOH and starlightoh are not the same input. Type it exactly as it appears, or copy-paste directly.
• Region lock: Some codes are distributed specifically for certain regional events or server populations. If a code fails with an "invalid" error rather than an "expired" message, it may simply not apply to your regional client.
• Already redeemed: Accounts can only claim each code once. If you've played across multiple seasons and tried a code during an earlier window, the system will reject a second attempt on the same account.
• Expired pool: Limited-use codes expire when the redemption count hits the developer-set cap, not necessarily on a calendar date. An active-looking code can stop working mid-day if it was high-traffic.

Why Free Codes Hit Differently in Once Human

Once Human launched on Steam on July 9, 2024, developed by Starry Studio, a subsidiary of NetEase Games. Its debut was significant: the game peaked at 231,668 concurrent players on July 14, 2024, placing it fifth on the list of biggest Steam launches of 2024 by peak concurrent users. It held those numbers better than most survival titles tend to, with Steam averaging around 26,000 concurrent players monthly in June 2025, spiking to roughly 51,000 at peak, and sustaining approximately 46,000 peak concurrent players through July 2025.

The mobile expansion on April 23, 2025, drew more than 30 million pre-registrations on Android and iOS before a single player had loaded the app. That launch included cross-play, cross-progression, and a promotional partnership with Ed Stafford, the survival expert and explorer who served as a brand ambassador for the mobile rollout. By any measure, the game arrived on mobile with unusual momentum.

A PlayStation 5 and Xbox Series X/S release is planned for later in 2026, which means a fresh wave of console players is coming to a game where some of the most experienced PC veterans have been sitting on optimized builds and Wish Machine knowledge for nearly two years. For those newcomers, a 2,000 Starchrom head start from two quick code redemptions is exactly the kind of friction-reducer that determines whether a new player pushes into the mid-game or bounces in the first week.

Where to Find Future Codes

Starry Studio distributes new codes primarily through the official Once Human and Out of the Blue social channels, developer livestreams, and creator partnerships on YouTube, Twitch, and TikTok. Patch notes and seasonal event announcements occasionally include embedded codes as well. Following those channels directly is the fastest way to catch codes before their use caps are hit. By the time a code makes it to an aggregator page, the highest-traffic ones can already be partially depleted.

The two active codes right now, 2026SFOH and S3STREAMER, are your clearest path to free Starchrom this month. Redeem them before the console launch makes this page significantly more competitive.
