Go to the download manager containing the 2 files you have just downloaded. You will see an APK and OBB file. The APK file will be much lighter than the OBB file.
Next, you click on the APK file to pre-install this file for your mobile device. Then, you go out and set up the OBB file.
First, you copy this OBB file, exit and go to Android folder. At this point, your directory will have 2 parts including data and OBB. You click on OBB and create a new file named Fishing Strike OBB.
Finally, gamers can go to the file we just created and paste the OBB file we just copied. Now, you just need to exit the screen and click on the Dead by Daylight icon on the screen and enjoy the game.
