You won't be able to keep this one in your library, but hey at least you can play it for a couple of weeks 
... You also get some sort of Holiday Pack 
Pretty good game IMO, the episodic **** sucks a little bit though, having to buy all of the missions seperately is pretty dumb, but now that there's a Game Of the Year edition that contains them it's all good 
... just gotta wait for a decent price during a sale ... ohhh winter sale, come out come out wherever you are 
Nice, love me some Hitman, hopefully can play some after xmas, busy busy busy!
oh we won't be able to keep it? that's disapointing
U keep the holiday pack (Paris)

That’s why the 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.
