Spec score 8.0 #7 of 24 in Game Asset Extractors

What it is

UABEA is a free reader and writer for Unity Asset Bundles and Serialized Files on Windows and Linux. Its maker positions it for modding and research rather than general asset extraction. The tool handles textures, TextAssets, fonts, audio, MonoBehaviours, Unity Asset Bundles, Unity Serialized Files, and Addressables bundles, and supports batch extraction and archive repacking. Editing Addressables requires clearing CRC checks with a separate CRC cleaning tool. UABEANext, a newer work-in-progress version, adds docking and multi-bundle opening. The latest listed release requires .NET Runtime 6.0. Windows also needs the Visual C++ Redistributable; Linux requires glibc 2.29 or later, and musl-based distributions require compiling UABEA. Font import and export covers TTF and OTF, but font atlases are unsupported. Swizzled Switch textures can be edited, while newly added textures are not automatically swizzled. The repository identifies the software as MIT licensed.
