Dig through that, learn the game's many long and greasy ropes, and you'll find the back half: a competitive strategy game so finely balanced and so tactically varied that people are able to play it as their job.'Watching your host chew Terrans into scrap metal and ripped flesh is consistently enjoyable.' The front half: a 20-odd mission campaign with a steadily evolving spread of controllable units spurred on by an earnest, overwrought story of revenge. The most important of these is cribbed from football: it's a game of two halves. StarCraft 2: Heart of the Swarm was designed to be a competitive sport, so it's only fair that it nicks some of sport's idioms.
