The differences/fixes between the demo and full version

I don't know, but to me, 'Improved AI' is about as reliable a comment as Coke saying their Diet brand tastes the same. It's such a generic statement and every developer says it because it at once makes the game seem better/improved while being wholly unquantifiable.|||its good to know they are fixing the AI. I do wonder why
they are addressing the body shot spamming exploit and not
the head spamming exploit which is way more of a problem.
Either way its a relief to hear its being worked on.
