Great news for the Alan Wake franchise! Yesterday Remedy's CEO, Matias Myllyrinne, announced that the title has now sold over 4.5 million units.
The last update given on the sales was from March 2012, in an interview with CVG. At that point, the team was celebrating selling over 2 million copies of the game. News of the new total came through Twitter:
Happy on behalf of the team: #alanwake franchise is past 4,5M units. The info floating around is a little old #xbox360 & #PC
