One device that will take off will be a little black box that, when connected to your mobile phone, allows you to create a virtual keyboard meaning you can tap away on a pub bar, for example, without the fiddliness of a phone keyboard.
The missions - which include rescues, demolition and ambushes - and the graphics have a pleasing air of authenticity, and an exemplary control system manages to sidestep any fiddliness. The two-player mode is also impressive.
