Next time your pop your Crackdown disc in (and you are connected to Xbox Live) you’ll get prompted for a title update. According to what I am told, The update ‘addresses several minor technical issues to ensure a smoother online gameplay experience’ and ‘increases the number of ambient gang vehicles that populate Pacific City.’ That last one should held with the ‘Repo Man’ achievement.
There ya have it. What’s up with any DLC? No details yet…but we should have some news soon in it.
