This whole Stunt Position mechanic makes so much more sense now. If you've played Just Cause 2 on your console of choice or PC, you will automatically unlock a Rico Rodriguez outfit for use in Sleeping Dogs. And not only will you look like Rico, but the outfit grants the player a bonus which will make it so you can make Stunt Position moves from further distances.
