Don't buy Deus Ex: The Fall if your idevice is jailbroken.
Deus Ex: The Fall, the mobile game sequel to "The Icarus Effect" book, will detect if it's being played on a jailbroken device and disable the player's ability to fire.
As soon as players are dropped into the game and attempt to fire, they're presented with the message "We are sorry but you can't fire on jailbroken devices."
Attempts to curb piracy are one thing, but Square Enix may be going a bit over the top with its DRM. "This is massively offensive on Square Enix's behalf," said KipEnyan, a Reddit user who posted about his problem to the website. "The obvious implication is that all jailbreakers are pirates who more than likely pirated this game. I paid good money for this game and [Square Enix] feels it's okay to break my game because I prefer to customize my iPhone to my liking."
Though jailbreaking mobile and tablet devices is usually warranty-voiding, it's not illegal. Square Enix may be overstepping its bounds as a publisher in attempting to police its customers' behaviors. Not to mention, this move may actually drive customers away, as there are plenty of people, like KipEnyan, who purchased the game despite having the ability to pirate it. It just means that Square Enix will be losing out on purchases from potential players who have now been alienated and are forced to seek out alternate means to play the game.
