on Steam PS4 and Xbox One
Download the game through your steam client
in order to obtain the Holiday Pack.
Back in June, The ICA Facility mission of Hitman became available for free along with two Escalation Contracts, more than 40 challenges, 17 achievements and trophies, plus thousands of player-created missions in Contracts Mode.
Along with aforementioned things, if/when you get the game now, you will receive free access to the Paris destination plus all of the Escalation Contracts released for Paris, ‘Holiday
Hoarders’ mission plus the Paris Challenge Packs and achievements too!
It will also allow you to play the future re-activated Elusive Targets
in Paris.
All of your progress and mission mastery will carry through to the full
game when you choose to upgrade to the Game of the Year Edition that was
released last month.
The game can't be added to the Steam Library just like the others so, from what I figured out, you need to download and launch the game in order to claim all the free content so, be sure to do that.
Hitman Holiday Pack is only available for a limited time, from
December 15th to January 5th. Once you’ve downloaded it, Paris is yours
to keep permanently.
Hitman is an episodic stealth video game developed by IO Interactive and published by Square Enix. It is the sixth entry in the Hitman series. The game's prologue acts as a prequel to Hitman: Codename 47, while the main game takes place seven years after the events of Hitman: Absolution.
In Season 1, 47 fulfills several assassination contracts for the
International Contracts Agency. Though the contracts at first appear to
be unrelated, an unidentified man, referred to only as the "shadow
client", has covertly coordinated these contracts to attack a secretive
organization called Providence, so that the ICA will appear culpable
while disguising his own involvement. The final contracts of Season 1
address the fallout caused by the ICA uncovering the shadow client's
actions, and by Providence discovering the ICA's role in the attacks.
