It is an action-adventure stealth-based video game series, although it is possible to switch between third-person and first-person perspective except in "Hitman: Codename 47", which offers an optional camera angle comparable to one used in fixed-camera adventure games, and the games from "Hitman: Absolution" onward, which exclusively employ a traditional, over-the-shoulder camera angle identical to video games such as "Resident Evil 4".
