Wait, the user might not know about the OBB file structure. Need to explain that it's a Google Play Expansion file, hence the .obb name. So after downloading, use a file manager to paste it in the correct directory.
Also, maybe the data file isn't separated. Some games have the data in the APK, others in OBB. Max Payne 3 for Android probably uses OBB. Confirming that might be tricky without prior knowledge, but it's a common structure. download max payne 3 apk data for android upd

I should make sure the user is aware that distributing copyrighted games without authorization might be illegal. So I need to mention that in the guide. Next, possible steps to download the APK and OBB: maybe using a reputable third-party site since the game isn't available on the Play Store. I should warn about potential malware risks.
Wait, should I mention using tools like Lucky Patcher for offline installation? Or is that unnecessary? Maybe it's better to avoid such tools since they can be risky. Instead, stick with direct APK and OBB installation.
