It's everything you need to know about the first expansion, Criminal Activity.
This new add-on boasts fresh maps, guns, vehicles and equipment, along with a new Bounty Hunter Mode. Oh, and you can play dress-up if you so choose; there are six new masks, including one freaky rabbit one (see the picture here).
Here's the summary:
Criminal Activity should be ready to go next month, and it's just the beginning. Three more expansions will follow: Robbery, Getaway, and Betrayal. If you picked up the $50 Season Pass, you'll get them all at no extra charge; if not, chances are, you'll have to shell out $15 for each expansion (no official pricing just yet).
