Fancy a break from shooting ethnic minorities in the face in military shooters? Then why not give your old thinking sponge a real workout with Valve's fantastic and fiendish follow-up. This first-person puzzle platformer has you creating two doorway portals with a special gun to move through a huge lab/prison. It's a sterner challenge than the first game and a longer game too, but you'll persist unto the end thanks to a great story, some very witty dialogue and an amusing turn from Stephen Merchant.
