The first Hitman 3 first-person mod has been released online, allowing players to experience almost all of the latest entry in the series with a first-person view.

The mod is mostly functional, as it works on every mission in the game, including seasonal missions from Hitman 2. There is still some work to be done, as there some issues here and there and there is no crosshair to aid in aiming.
