Hitman 2 is an action/adventure game developed by IO Interactive and published by WB Games for PC, Xbox One, and PlayStation 4.
Hitman Legacy Pack
For owners of the previous Hitman game a pack of downloadable content was made available for free that contains all the previous episodes of the game. These episodes are playable within Hitman 2 using the new gameplay improvements.
There are two available options depending on which version of the game players owned. One is the base game pack and the other is the Game of the Year Edition pack. Both of these packs can be purchased for players of Hitman 2 that did not previously own the previous Hitman.
