Attack on Titan: Humanity in Chains – Update 1.2 [Decrypted] 3DS (JPN) ROM Free Download

You're looking at the Update 1.2 package for Attack on Titan: Humanity in Chains (known in Japan as Shingeki no Kyojin – Jinrui Saigo no Tsubasa CHAIN), delivered as a decrypted .3DS ROM that runs on the Citra 3DS Emulator for Windows. This is the Japanese-region release published and developed by Spike Chunsoft on July 2, 2015, and the update file adds the latest balance and content fixes on top of the base game. If you're setting up the game for emulation, this page gives you the exact files, sizes, and practical guidance to get moving.

Technical Specifications

What This Update Delivers

The base game puts you in the boots of the Survey Corps, fighting towering Titans with the omni-directional mobility gear that defines the Attack on Titan universe. The 1.2 update refines that experience with adjustments to combat flow and mission balance, and it's packaged here as a separate 226MB download alongside the 957MB base game. You'll need both parts to run the complete, updated title in Citra. The ROM is decrypted, meaning it's ready for emulator use without additional decryption tools — a practical detail that saves you a step if you're new to 3DS emulation.

Key Features

• Omni-directional mobility combat: Grapple and swing through maps to strike Titan weak points, capturing the series' signature movement style.
• Character roster from the anime: Play as Eren, Mikasa, Levi, and other familiar faces, each with distinct stats and roles.
• Mission-based campaign: Undertake operations to defend humanity's last walls, with objectives that escalate in difficulty.
• Update 1.2 content: The latest patch package for the Japanese release, applied on top of the base ROM.
• Decrypted .3DS format: Built for direct loading in Citra without extra conversion.
• Localized Japanese release: Full Japanese language, matching the original JPN region version.

Pros & Cons

• Pros: Faithful action gameplay that mirrors the anime's combat; decrypted format simplifies emulator setup; update file is small at 226MB; runs on the widely used Citra emulator for Windows.
• Cons: Japanese-only language, so you'll need familiarity with the menus or a translation reference; requires the separate base game download; performance depends on your Citra configuration and hardware.

Version Freshness and Publisher Details

This is the Update 1.2 release for the Japanese version of the game, dated to the original 2015 launch window. The publisher and developer is Spike Chunsoft, a studio with a long history in action and role-playing titles. The decrypted ROM is distributed as a free download, and the file size is listed at 957MB for the base game with a 226MB update package. Keep in mind that the version number here is an estimate based on the update label — always confirm the patch level in your emulator after installation. If you run into missing shared fonts or archive errors in Citra, the standard fix is to install the shared fonts from the emulator's setup guide.

Installation Guidance

To get started, download both the base game and the Update 1.2 file from the links above. Extract the RAR archives using WinRAR or 7-Zip — there is no password on any of the game files. In Citra, install the base .3DS file first, then apply the update. If Citra prompts for archive files or throws a fatal error, grab the shared fonts from the Citra setup page. Make sure your WinRAR is up to date, since older versions can incorrectly ask for passwords. If a RAR shows as damaged or you hit a CRC error, re-download that part before troubleshooting further.
