I think if it is a personnal project no matter with copyright.
And i doubt a lot the game to go such quality as the last Predator game on PC !

Why not making original characters, space ships, planet based on hunting with new weapons, powers instead of copying the AAA game ? And there are older predator games, i doubt you reach such
textures, level design ,sound, music and models quality !

Well no matter for a personnal project just go on and make it
