As someone that loves acquiring in-game cosmetics through various challenges and achievements, the constant rise in pre-order DLC has been a massive annoyance. Rather than unlock cool new things by playing the game, these days you unlock new things by blindly throwing your money away, desperately hoping the pre-release trailers weren't of the "vertical slice" variety.
With that in mind, I am very glad to say that all of Deus Ex: Mankind Divided pre-order DLC has now been made available for free, for everyone! What this means is that you'll now have access to the Desperate Measures extra in-game mission, a whole bunch of armor and trench coat skins, a re-skinned pistol and combat rifle, as well as a variety of consumables.
And for those of you that want to learn more about the Deus Ex world, three digital books have also been made available. You can find the novella "Deus Ex: Hard Line", the mini comic "The Dawning Darkness", as well as the official artbook by heading over here. The download is around 200MB in size, so even if you're under a data cap it shouldn't be too big of a deal. Enjoy!
