From the R* mail list, I've been getting these emails with the trailers, technology demos,
and how they made the game type stuff. It says he starts as a beat cop and moves up to detective,
but not using the traditional mission system. More involvement and clues lead to other
opportunities. Also besides the 32 camera HD facial system for the actors, the script
now includes basically what we know from Fallout as "speeching". So by taking new cases
on, and speeching outcomes, will provide new outfits that he may not have gotten otherwise.
Unlimited amount of cases open at any one time, based on your initiative to finish them.
Also there is the negative side of it, missing out on outfits because he didn't progress
in a crime or speech a certain person the right way to get a rare outfit.
