Naughty Dog's new IP, The Last of Us, is doing very well in its first week on sale. The game has sold 1.3 million copies in the first week of its release, making it the biggest launch of the year. BioShock Infinite sold 1.16 million units across two platforms - the PS3 and Xbox 360.
This means The Last of Us has sold over 200,000 more copies and considering it's a PS3 exclusive - that is some good business for Sony. The Last of Us has sold around 500,000 copies in the US, which represents a near 50% increase over the 338,000 pre-orders. In the UK, the game is selling well, with around 120,000 units shifted so far.
