Best Map: Sapienza. The best map, without question. It is the only map with three variations, and has the most interesting use of Elusive Targets that emphasize parts of the map that the main missions do not. Paris may have the most Elusive Targets of any location and may make thematic sense, but quite a few just overlap and feel more like they’re being sandwiched into the location instead of really capitalizing on the space and location they’re in. The Prince and The Guru are how you do ETs: you emphasize them in places that are really off the main direction of the objectives and turn them into deeper puzzles to navigate.
Worst Map: Carpathian Mountains. It exists solely to end the story, and it might be the most linear final stage in Hitman history. Maybe only beaten by Blood Money, but that was more of a spectacle scenario, which redeems it. The only time you’re ever replaying this location is if you’re doing a full storyline playthrough of the game.
