Playing a character on the other side,
having to solve crimes, hunt murder's, should make the game play different.
Also uses the "latest" facial animation technology so the play can try and pick up on if the character is lying ect by how the react.
Will be interesting to see how its done, hopefully the crimes are not too easy and the game takes time to finish like GTA and Red Dead Redemption
