Finally Platinum'd this. Offers perhaps the best level (in terms of design and gameplay) in the trilogy with Berlin, but the rest is more of the same - which, if you're a fan of the series, is hardly a complaint. Pretty great gameplay and I think it has overall the most consistently enjoyable run of levels (Hitman suffers in the middle, as does 2), but IO-I have really dropped the ball with all the stupid online features, the recycled elusive targets and, though I haven't bought them so can't say for sure, the "Seasons of Sin" (lol) are pretty underwhelming. Oh well. Fun game!
