SAND asset bundles

Unity addressable asset bundles for SAND (Unity 6000.0.40f1), shipped under Sand_Data/StreamingAssets/aa/StandaloneWindows64/. Reachable here via the bundles/ symlink (git-ignored). 35 bundles, ~6.8 GB total.

Each bundle embeds a serialized Unity .assets file. The Assets column below counts addressable entries (the bundle's m_Container map) — the named, loadable assets — not the raw sub-object count (a single prefab expands into many GameObject/Transform/Mesh objects).

Read the bundles in Python with bundle/extract_data.py / loot_probe.py (UnityPy + an IL2CPP typetree generator), or the minimal bundle/unitybundle.py UnityFS extractor.
