This list is for anyone who wants to know the order of each piece of media, AvP movies are no longer canon, Also this list does not include the canon comics. It is hard to find canon comics ever since Ridley Scott changed the canon (Like Disney did with Star Wars) This list is the best so far for continuity. Everything after "Aliens (film)" was almost rebooted with a cancelled sequel that would have changed everything after that point.
