People love games that let them shoot things and people love games where they get more stuff. So, how many units do you think a game that combines the two would sell? If your guess was 7.5 million, congrats, you have an eerily-specific market sense, or maybe just pay attention to headlines.
The game has done so well that it's currently on track to becoming the highest-selling title in publisher 2K's history, according to company president Karl Slatoff.

The first part of the pack, TK Baha's Blood Harvest went on sale Oct. 22.
