Deus Ex is, by nature, a complicated game. You can start by simply moving around a level: There's cover to move in and out of, and stealth movement requires good timing and precision. Then, there's all of the abilities you have, from using various gadgets and weapons to choosing your bio-implants and playing the hacking mini-games. That's a lot of buttons. In making Deus Ex: The Fall for iOS devices, Square Enix Mobile was given the task of putting all those functions into a device that has only one button.

In that respect, the most exciting news about this game is that it works. For the most part, that is. You can't hide bodies, for one thing.
