The rules of the game are simple. First download the demo and give it a play. Then take a look at the set of awesome medals you can unlock in the full game. Then head over to Twitter and tell us which medal you most want to get and why. We'll pick out four lucky entrants on Tuesday night and out the codes via Direct Message on Twitter[.]
