'Deus Ex: The Fall' Prevents Players With Jailbroken iOS Devices From Firing Guns
Encountered by Redditor KipEnyan and verified by several user reviews in the app store, jailbroken players starting up the first mobile installment of the Deus Ex series are treated to a few cutscenes and a movement tutorial before running into the message above. It comes up during the game's shooting tutorial, and while one would assume players could still stealth through the game, I'm not sure they can progress beyond that point without tranquilizing those guards.
Eidos and N-Fusion, the development firms behind Deus Ex: The Fall likely implemented the measure to deter piracy, as jailbreaking is a requirement to pirate software, though not all users who jailbreak choose to pirate software.
As a result, users who choose to jailbreak for other reasons but pay for their software get caught in the same net as the pirates. It's not the first time that developers have resorted to similar tactics to stop pirates, although it is unusual for such a high-profile developer to target not just pirates but all jailbroken users.
Earlier this year the publisher of Game Dev Tycoon encoded features into the game that would bankrupt players who didn't pay for their copies, while DirecTV prevents users with jailbroken devices from using its app at all.

Update: An unconfirmed source has indicated that the anti-jailbreak code was included in Deus Ex: The Fall at the request of publisher Square Enix and that an update is in the works to remove it.
