A reputable leaker from Neogaf has confirmed that Devil’s Third sold 3,000 units in retail stores last month in North America. For those that have been following along with Devil’s Third’s story, this should not be a surprise. The game was very difficult to find, and the copy was only found in Gamestop locations around the country. Even then, most could only find the game by paying exorbitant prices on eBay.
Keep in mind, these sales are just in the American territory, and do not include digital sales. Nevertheless, it is pretty clear that the game performed pretty poorly across the board.
