Why the update can fail even if the final game is smaller

Update data and temporary extraction files can exist at the same time. That makes the peak requirement higher than the update download alone. GRYPHLINE says the temporary files are removed afterward and that Homecoming consolidates mobile resources, so final installed size and peak working space are different numbers.

How to install the Homecoming update

  1. PC: close the game, restart GRYPHLINK, then choose Update. An SSD is recommended.
  2. Android: open the game and follow the update prompt. Mobile pre-download is not available for this version.
  3. iOS: open the App Store and choose Update.
  4. PS5: highlight Arknights: Endfield, press OPTIONS, then choose Check for Update.

Fresh install vs. Homecoming update

A fresh PC install has a different requirement: 50 GB for the game plus 40 GB during extraction, or 90 GB peak. The official base requirements list at least 25 GB for Android and iOS and 60 GB for PS5. Use the calculator's “Base install” option when installing from scratch.
