Set 25 years before the events of the original Deus Ex, the world of Human Revolution may require some explanation, even for series vets. A new dev diary released by Square Enix focuses on the rise of augmentations, and the two companies that vie for control over the market: Sarif Industries and Tai Yong Medical.

Of course, there wouldn't be much of a game if there wasn't any conflict. Inevitably, the rise of augmentation means that some are willing to exploit the technology. It'll be interesting to see how the consequences of your actions in Human Revolution set up the backdrop for the original Deus Ex.

Deus Ex: Human Revolution launches on PC, PS3 and Xbox 360 August 23.
