For anyone who grew up squinting at the pixellated, greenish screen of an Atari, it's sometimes impossible to believe quite what a mobile phone is now capable of doing. Modern Combat 5: Blackout (Gameloft, iOS/Android, £4.99), a portable Call of Duty equivalent that squeezes an FPS into your pocket, has graphics that would have seemed unfeasibly high-spec just a few years ago. Controlling modern military man Caydan Phoenix, the bite-size single player missions that make up the story are well suited to the medium and the non-story elements do a good job of breaking up the gun-toting action.

The drawback, as always with this type of game, is the controls. The on-screen sticks and buttons are easily mishit, particularly infuriating in multiplayer when a grenade is lobbed at the wrong time. The developers haven't yet included controller integration on iOS but it's promised for a future update.
