Possible to load an existing map to unreal engine?

Just getting started with unreal engine, i’ve never had any experience with this kind of program before. Don’t know if this is the right place to ask nor the right section of the forums but i thought i’d give it a shot. I was woundering if it’s possible to load a map from a game and then build on it. So for example, for the game Squad. Is it possible to load a Squad map into unreal engine and then work on it? Etc add more stuff or just delete things.

No, files in games are built and aren’t in the same format as they are when you are working on a map in a project.
