Resident Evil 2 Mobile APK was developed using Unreal Engine 4 and has good graphics. The gameplay is rather buggy and glitchy because this is not an official game. Someone just developed the android RE2 version. There are setting options that allow you to adjust the controls and graphics quality.
If you want to try Resident Evil 2 on Android then you can simply download Resident Evil 2 Mobile APK + DATA and install it as you did when installing another game. This game is from Fan and don’t compare it to the official title. This is only a Demo or I would say imitating the game RE2 on an Android device.
