Arknights: Endfield is a large game by modern mobile/PC standards, both in download size and in how much content it packs in.

Quick answer

  • On PC, you should expect roughly 50–60 GB of storage for the full install, plus extra temporary space during installation.
  • On mobile (iOS/Android), the game usually ends up around 24–28 GB after in‑game data downloads, depending on language packs and patches.
  • In terms of game scope, it features open‑world exploration, base/factory management, and long story content, so it feels “big” in both file size and gameplay time.

File size by platform

Here is a simple breakdown of how big Arknights: Endfield is on different platforms (numbers are approximate and can change with updates):

  • PC / Windows
    • Install size: about 50–60 GB.
* Extra temporary space during install: roughly 40–45 GB free space needed for unpacking.

* SSD strongly recommended for smoother loading of open‑world areas.
  • iOS
    • App size a bit over 3 GB, but total data after in‑game downloads can reach ~24–28 GB.
* Future voice packs and patches can push the size higher over time.
  • Android
    • Similar to iOS: around 25–28 GB free space recommended.
* Final size varies slightly by device and what assets/voice packs you install.

“How big” in gameplay terms

Beyond storage size, Endfield is also “big” in scope:

  • Open‑world exploration
    • The game lets you roam large zones, gather resources, and tackle encounters rather than only doing stage‑based maps.
* This design contributes heavily to the large client size because of terrain, textures, and environment assets.
  • Factory/base management
    • There is a detailed factory/base system with production lines and optimization layers, which adds a lot of systems and UI content.
* For players who enjoy long‑term planning, this makes the game feel more like a “big” hybrid of RPG, builder, and strategy.
  • Long‑form story and gacha structure
    • The game follows the Arknights tradition of heavy narrative, cutscenes, and voiced dialogue, adding to the total data footprint.
* Multiple high‑rarity characters, weapons, and animations also expand both playtime and file size.

Forum & trending context

  • Community discussions often highlight how surprisingly large the install is for a “mobile‑compatible” title, especially compared to classic gacha games.
  • Content creators who have played dozens of hours describe Endfield as “massive” due to:
    • Many hours of story and side content.
    • Deep building/factory systems.
    • Exploration zones that take time to fully clear.

In short, if you are wondering “how big is Arknights Endfield?” :

  • Make sure you have at least ~60 GB free on PC (90 GB temporarily during install) or ~30 GB free on mobile.
  • Expect a game that can easily occupy you for many dozens of hours thanks to its open‑world design and complex systems.
