Hitman: Absolution is full of challenges, wether they are related to a single mission or to the way you play the game. As you might have seen from the huge amount of weapons included into the game, there are plenty of ways of killing off your enemies, ranging from some simple strangling to some more creative ways that involve some environmental elements which can be used to trigger some accidental kills, kills that are more rewarding not only from an aesthetic point of view but also because they make you earn more points per kill which can be used to unlock some special assassin technique with ease.
Of the challenges included into the game, the playstyles are probably one of the most unique challenges: earning all playstyles is required to earn the Jack Of All Trades Trophy. There are a total of 20 playstyles in Hitman: Absolution and to get each one of them, you’ll have to perform a number of specific kills. Some of them you’ll probably get by playing through the game but some of them will probably require a bit more effort on your part. Here’s the full list of the Hitman: Absolution Playstyles.
