The System Rift DLC for Deus Ex: Mankind Divided is out now and adds in new story missions for $11.99 (USD) if purchased separately or as part of the $29.99 Season Pass.
In Deus Ex: Mankind Divided – System Rift, you will re-unite with Frank Pritchard, Adam’s friend and former colleague at Sarif Industries, and assist him in hunting down information on the mysterious Santeau Group. Desperate to get more information, Pritchard targets one of the most secure data banks ever created – the Palisade Blade. In agreeing to help, Adam may also be able to uncover hints as to who the illuminati really are.

Those damn Illuminati, always being mysterious and junk.

Also of note here is the fact that Deus Ex GO is on sale for 60% off from now until September 29. You can pay just $1.99 (USD) for this mobile game for the platform of your choosing (except probably Windows Phone).
