Yeah it's a bit cheap (assuming, which on the evidence it's fair to do, that the game will actually but untrue to such a context) but it's nothing movies haven't done for ages (or books for that matter).
TBH the tone and feel seems lifted directly from The Untouchables when the little girl is killed with an exploding briefcase to make sure the audience knows Al Capone and his outfit are bad people.
Try to be reasonable... its easier than you think...
