Under Guild: Offense v1.6.5 Released: Migrating from Legacy Builds

Under Guild: Offense version 1.6.5 has officially launched, resolving floor 50+ crash bugs and refining combat speed controls. Here is how to safely migrate your save file from versions 1.4.8 and 1.3.8.
Why v1.6.5 Replaces Older Releases (1.4.8 & 1.3.8)
Many players of Under Guild: Offense (available officially on Google Play) have been running legacy modded packages such as v1.4.8 or v1.3.8. While those versions served their purpose for classic tactical RPG & dungeon crawler progression, newer Android OS security patches (Android 14 and 15 preview) caused intermittent crash loops on deeper dungeon floors.
Version 1.6.5 completely overhauls the memory allocation for stage assets, eliminating sudden crashes during multi-wave boss encounters and ensuring seamless performance.
Step-by-Step Save File Migration
To preserve your hero roster and equipment upgrades when transitioning to v1.6.5, always link your account to cloud storage (Google Play Games or email login) inside the game settings menu before updating.
Because package signatures between unofficial releases can differ, uninstalling the older APK before installing v1.6.5 is recommended if the package manager reports an installation error.
Take a screenshot of your player ID and profile code in Settings as an extra safeguard before performing any package upgrades.
Tuning Dungeon Combat Speed
The verified Under Guild Modded APK v1.6.5 provides up to 8x dungeon battle acceleration. For optimal stability, use 4x speed during regular labyrinth exploration and reserve 8x for routine gear farming on previously conquered floors.
