There was a time when Lego really was just blocks. When we were young each of the little plastic people (who flew rockets made out of castle walls) were only present to add scale to our mismatched creations. Their sociopathic fixed smiles did nothing to add personality to the world. So it's hard to imagine a story built around them. Cue Lego City Undercover. Earlier Lego games sidestepped this problem, with movie and film tie-ins offering instant context to their charming humour and gameplay. While these licensed titles established a pleasing style for the Lego franchise, the little blocks have still got to prove that the brand can carry Nintendo exclusive Lego City Undercover without the support of Jones, Wayne or Solo. But this initial scepticism aside, Lego City Undercover makes a good first impression. Taking an open-world design that owes a lot to GTA, we play the role of undercover cop Chase McCain, who hopefully apprehends plastic villains, melts them down and remoulds them as model citizens.
