ENDFIELDSTEAM code unlocks 300k wishlist rewards. Arknights: Endfield launches October 15 on Steam

Players can now mark their calendars. Arknights: Endfield will launch on Steam on October 15, 2026. The announcement comes alongside news that the game has passed 300,000 wishlists on the platform, unlocking the final community milestone and a fresh batch of rewards.

A new redemption code, ENDFIELDSTEAM, is live now. Anyone who enters it before the cutoff dates can pick up T-Creds, Cognitive Carriers, equipment sets, and a commemorative portrait frame. The code works on all servers, though the expiration windows differ by region.

The 300k wishlist target was the last of several community goals tied to the Steam launch. Now that it is met, every previously locked reward tier is available to claim. No further wishlist actions are needed.

Rewards from the ENDFIELDSTEAM code

The code grants four items:

• T-Creds x8,000, the standard currency for in-game purchases.
• Elementary Cognitive Carrier x2, an item tied to character progression. Official materials do not specify its exact use.
• Arms INSP Set x2, an equipment set for operators. Details on its effects have not been published.
• Special Commemorative Portrait Frame x1, a cosmetic profile frame.

These are the same items that were listed as the final milestone reward. Anyone who missed earlier milestone giveaways can catch up by redeeming now.

How to claim the code

Open Arknights: Endfield on your platform of choice. Go to the settings or redemption menu. Enter ENDFIELDSTEAM exactly as written. Confirm the entry, then collect the items from in-game mail.

The code expires on November 25, 2026. But the exact deadline depends on your server:

• Asia Server: 2026-10-06 19:30 to 2026-11-25 23:59 (UTC+8)
• Americas/Europe Server: 2026-10-06 06:30 to 2026-11-25 10:59 (UTC-5)

Note that the redemption period starts on October 6, 2026, meaning the code is already active. Players on Asia servers have a later cutoff than those on Americas or Europe servers.

What the launch date means for new and returning players

October 15 is roughly a week after the code goes live. That gives players a short window to stock up on T-Creds and Cognitive Carriers before the servers open to everyone. For free-to-play and low-spend accounts, those resources can make early progression smoother.

The portrait frame is a one-time cosmetic item. It will not affect gameplay, but it marks the Steam launch period for collectors.

Sanctuary of Ink arrives alongside the Steam launch

The Steam release coincides with the Sanctuary of Ink update. Two new Operators, Si and Argent Flow, join the roster. The update also adds Contingency Contract: Indigo mode and an inn management feature. Players who redeem the current code will have extra resources to spend on that content from day one.

With 25 operators in the game at launch, team compositions will shift as the meta settles around the new additions.

The ENDFIELDSTEAM code expires in late November 2026. After that, the rewards are gone.
