Since it rebooted its Hitman franchise in 2016, IO Interactive has been putting on a level design masterclass. Each of the missions the developer rolled out in what it calls its World of Assassination series has contained a huge, intricate collection of scripted and free-form systems that create harrowing moments, presented elaborate puzzles to solve, and allowed the player to orchestrate ludicrous and often hilarious situations. Levels are designed to be played over and over so you can explore, understand, and eventually master all their moving parts, and it’s impossible to see everything one has to offer in a single playthrough (or in most cases, even two or three).
