The Witcher 3: Wild Hunt sold more than 6 million copies during its first six weeks, developer CD Projekt Red announced on Wednesday. The company revealed the new sales figure, up from 4 million in its first two weeks, as part of its latest earnings report. The exact sales figure is 6,014,576.
Released in May to glowing reviews, The Witcher 3 is expected to be the final entry in hero Geralt's story, though not necessarily the last game in the series. Whatever the case, you shouldn't expect CD Projekt Red to release another Witcher game anytime soon, as the Polish studio is now focusing on Cyberpunk 2077.
