Hitman brought a much-needed sandbox approach to the stealth trifecta of Metal Gear's epic narrative and Splinter Cell's realism back when each series was finding its feet, and it's something the other titans in the genre have since taken many liberties with. For Unity, Ubisoft tried to incorporate this element of game design and gave you select times where taking out your target would mean a range of approaches could be implemented, although all this boiled down to was Arno somehow listening in to conversations a few blocks away or sabotaging a piece of the environment to clear a passage further in. The idea is solid, as the aforementioned Hitman titles built their name on allowing you to play with the environment just as much as Metal Gear did its guards. However Unity's lack of telegraphing exactly what doing one option would mean for the larger picture made for a lot of cack-handed tinkering and restarts overall. Many welcomed the focus on assassinating a particular target and having a defined run-up to said event, as that was a focus in the first game, but they're over way too quickly. In addition the means by which Arno obtains his information don't even make sense, as he appears to be aided by the Animus, despite surely not being aware of it.
