Downlink Escape

This is an escape game where you have to find books laying around the map containing values to put into the computer. Once you get a signal from a satellite, you will be given a piece of the code to escaping. Connect with all four satellites and you have all of the digits for the code to escape.
It is my first time packaging in Unreal Engine and it just doesn't work :( Idk how to take this post down either
