Google play store has 100MB policy. Most 3D games lower than 100MB but they have in game download system. When you download game from google play store you download it 70MB but when you open the game it start downloading 500mb game assets. Is it possible to that in ue4 ?
This is possible via the Play Asset Delivery tool or the Mobile Patching Utility which requires you to have the pak files hosted externally via a service like Google Cloud
