Once Human 10,000 Starchrom: How to Claim Free Isles of Abyss Rewards

Once Human 10,000 Starchrom is a free sign-in gift for the Isles of Abyss launch. After the October 21 Pacific-time update finishes, open your in-game mailbox to claim the Starchrom, Cosmic Visitor and Snowline Elite Vest blueprints, a Meta Pass trial and three Howler skins.

You have until November 8 at 2 PM Pacific, or 10 PM GMT in the UK, to collect it. There is also a smaller maintenance compensation package. Those are two separate giveaways, so check both when you’re back in the game.

How to claim Once Human 10,000 Starchrom

To collect Once Human 10,000 Starchrom, log in after version 3.1.1 maintenance, open the mailbox and claim the Isles of Abyss celebration supply. No dungeon completion or separate purchase is listed as a requirement for this sign-in gift.

If you can’t see the celebration message, first make sure the update has finished and your client is up to date. The gift arrives by mail after maintenance, so it won’t appear while the servers are offline. Look for the Isles of Abyss celebration supply, not just the separate compensation.

What is included in the free gift?

The package contains 10,000 Starchrom, the Legendary SOCR – Cosmic Visitor weapon blueprint, the Legendary Snowline Elite Vest gear blueprint and a 30-day Meta Pass Trial Card. You also get three Howler weapon skins for DE.50, MP5 and EBR-14.

Both equipment rewards are blueprints, rather than finished weapons and armour you can equip immediately. After claiming the mail, find them in the relevant blueprint menus. The Howler cosmetics are tied to their named weapons; one skin won’t fit every gun.

Free launch gift	Amount
Starchrom	10,000
Cosmic Visitor blueprint	1 Legendary weapon blueprint
Snowline Elite Vest blueprint	1 Legendary gear blueprint
Meta Pass Trial Card	30 days
Howler weapon skins	DE.50, MP5, EBR-14

Is the 1,000 Starchrom compensation included?

Maintenance compensation consists of 1,000 Starchrom, 100 Mitsuko’s Marks, one Epic Stardust Secret Crate S15 and 30 Colorful Badges. NC announces these separately from the larger Isles of Abyss launch gift, which is the Once Human 10,000 Starchrom package.

Claiming both announced sets would give you 11,000 Starchrom in total. That extra 1,000 comes from compensation; it isn’t part of the 10,000-Starchrom celebration mail. Check for the two rewards rather than expecting all items in one message.

Once Human 10,000 Starchrom claim deadline

The last stated time to claim the Once Human 10,000 Starchrom celebration supply is November 8, 2026 at 2:00 PM PT, or 10:00 PM GMT in Britain. Collect the mail before that deadline, especially if you’re not planning to join the new scenario straight away.

The giveaway doesn’t require you to log in the instant downtime finishes. The official window lasts until November 8. If the servers are still offline at the estimated reopening time, check the developer’s maintenance notice instead of assuming the reward is missing.

What are Cosmic Visitor and Snowline Elite Vest?

The Cosmic Visitor rifle generates Frost Vortexes and is guaranteed to spawn a vortex on the first hit after reloading. It also creates automatic homing Ice Spears. The Snowline Elite Vest makes Frost Vortex-triggered effects activate once more and builds a damage bonus through repeated vortex generation.

If the Once Human 10,000 Starchrom package introduces you to this equipment, read our SOCR Cosmic Visitor weapon guide and Snowline Elite Vest guide. Both now include the confirmed free blueprint acquisition details.

Do you have to join Isles of Abyss first?

The Once Human 10,000 Starchrom gift is available for signing in after the update. NC doesn’t require an ocean boss kill or a visit to RaidZone. You can claim the items first, then choose which scenario to play.

Collect the mailbox gift before the deadline, then choose which scenario to play. Our Isles of Abyss launch guide has the platform download sizes, and the joining guide explains PvE registration and RaidZone entry.
