It is always a good sign when a game ships over a million copies, but when a company can ship at least two million copies of their game then it is easy to assume that the game is at least doing well. Though this is games shipped, not sold, the title has reached the top of both UK and US sales charts for last month. Plus, the more games sold, the more that need shipping.
With Human Revolution being an absolutely amazing experience, as you can see in my review, and with the Missing Link DLC coming next month, Square Enix and Eidos Montreal are doing their best to make sure people pick up this title. It is also worth noting that the title has not yet been released in Japan and these figures are from North America, Europe and PAL territories.
