"As you may have already seen by reading and watching the many previews for Deus Ex: Mankind Divided, our aim is for it to be a worthy successor to Human Revolution, and to improve upon that game in every way possible. I know that expectations are extremely high, and we not only want to meet those expectations, but exceed them.
We’re confident and proud of the game so far. However, as we are now playing through the game in full we can see that it will require more time in post-production for tuning, iterations, and refinement to meet our high standards. In order to achieve this, we need to move the release of the game to
August 23rd, 2016.
We are sorry to disappoint you with this news, and also thank you for all of your support and comments. This game is a huge part of our lives, and we don’t want to compromise on its quality.
So please be patient with us a little longer, and thanks as always for your passion and support – through thick and thin. It’s a huge responsibility to work on Deus Ex Mankind Divided - we know, but also a huge privilege. We’re determined to deliver the best game we can."
