Multiple "Paths"?

[Enigma9001]

I think this thread is in the right place, but I'm sorry if I got it wrong.

I'm new to the forums (to be honest, I've lurked around here only a few times in the past) and new to modding. I'm trying to teach myself how to mod Amnesia (obviously). I have a custom story in my head, but before I do anything about it I have a question.

Would it be possible to create "multiple paths" in a map? For a simple example: there are two paths you can take in a map. You can only take one path (cannot go back and take the other once you've chosen) and something happens in the story. However if you took the other path, something completely different would happen.

If possible, could multiple endings be achieved?
