OBB (Opaque Binary Blob) files are data expansion packs for Android games. In Modern Combat 5, the APK (the installer) contains only the core engine and menus. The OBB file holds the heavy assets: HD textures, soundtracks, mission maps, character models, weapon effects, and cutscenes.
APKMirror (owned by Illogical Robotics) – Safe, but they provide APKs only, not OBBs.
APKPure – Provides both APK and OBB in a single .xapk file.
RevDL – User-uploaded, check comments for “OBB works.”
