Did you know that as well as a games, music and pointless-format movie player, the PSP also works as a time machine? Or so it seems when you're playing SWAT: Team Liberty. Boot up this game and you too can journey back, way back, to a time when it was okay for videogame characters to be implausibly stupid, capable of saying only three different things, and called names like Kurt Wolfe. Unfortunately it's 2007, and these sorts of things are not okay any more, and SWAT: Team Liberty is not much fun at all.
