Technical Specifications

What Is Attack on Titan: Humanity in Chains?

Attack on Titan: Humanity in Chains is an action game that adapts the first two seasons of the Attack on Titan anime. You play as members of the Survey Corps, including Eren, Mikasa, and Armin, as they fight to reclaim territory from the Titans. The game combines fast-paced combat with a mission-based structure, letting you take on story missions and side quests that expand the narrative.

The core loop involves zipping through the air using omni-directional mobility gear, targeting Titan weak spots, and managing your gas and blade durability. It's a system that rewards timing and positioning rather than button mashing. The 3DS version includes local multiplayer for up to four players, so you can team up with friends for co-op missions. The game also features a character customization system where you can create your own Scout and upgrade their equipment.

This USA ROM is specifically prepared for Gateway and Sky3DS+ flashcarts. That means you can run it on a physical 3DS console without modifying the system's firmware. The file is a standard .3DS format, and it's region-locked to USA, so it will work on North American consoles. If you're using a European or Japanese console, you may need to consider region compatibility before downloading.

Key Features

• Faithful adaptation: Relive key moments from the anime's first two seasons, including the Battle of Trost and the Female Titan arc.
• Omni-directional mobility combat: Use gas-powered gear to zip around the battlefield and strike Titan weak points with precision.
• Character progression: Customize your own Scout, upgrade weapons and gear, and unlock new abilities as you complete missions.
• Local multiplayer: Team up with up to three friends via local wireless for cooperative Titan hunting.
• Multiple playable characters: Take control of Eren, Mikasa, Armin, and other familiar faces from the series.
• Mission variety: Engage in story-driven missions, side quests, and survival challenges that test your combat skills.
• Flashcart compatibility: Designed to run on Gateway and Sky3DS+ flashcarts on real 3DS hardware.

Gameplay Deep Dive

Combat in Humanity in Chains revolves around the mobility gear. You'll lock onto a Titan, fire your anchors, and reel in to deliver a slash. Each attack consumes gas and dulls your blades, so you need to manage resources carefully. The game also includes a dodge mechanic and a boost function, giving you options for both offense and evasion. Titans come in different sizes and types, each with their own behavior patterns. Some are slow and lumbering, while others are fast and aggressive. Learning these patterns is key to surviving later missions.

Between missions, you can upgrade your gear using materials collected from fallen Titans. The crafting system lets you improve blade sharpness, gas capacity, and anchor range. You can also develop new equipment that unlocks additional combat options. The game's progression system is tied to your character's level, which increases as you complete missions and earn experience points. This creates a satisfying loop of fighting, looting, and upgrading.

The story mode follows the anime closely, with cutscenes that use still images and voice acting to convey key plot points. If you've watched the anime, you'll recognize the major beats. If you haven't, the game provides enough context to follow along. The local multiplayer mode is a separate option where you and up to three friends can take on missions together. Each player controls a different character, and you can coordinate attacks to bring down larger Titans more efficiently.

Who Is This ROM For?

This ROM is intended for players who own a North American Nintendo 3DS and a Gateway or Sky3DS+ flashcart. If you prefer to play on original hardware rather than an emulator, this is the way to go. It's also a good fit for fans of the Attack on Titan series who want a portable action game that stays true to the source material. Collectors who want to preserve the game in a digital format will find the .3DS file useful for backup purposes.

If you're new to 3DS flashcarts, you should know that setup requires some technical steps.

Be sure to follow the instructions that came with your flashcart to avoid errors.
