So, for a very tense single xenomorph experience, kinda faithful to the Alien Film, then AI is the one to go for.
Nothing wrong with either I suppose, depends what you would like to play.

There are YT guides etc that can help with the installation of AI.
You will note a link above that I made about the symbolic link that seems to be needed when launching it under Windows 11, that automates, somewhat that process.
