Assassin's Creed Dead Kings DLC for free! Or free Ubisoft game

Ubisoft has announced that AC Unity's DLC Dead Kings will be free for every one who owns AC Unity. They do this to make apologies for the issues that the game has.
And what about the guys who buyd the season pass? They can chose one free Ubisoft game from the following list:

- The Crew
- Far Cry 4
- Watch Dogs
- Assassin's Creed IV Black Flag
- Rayman Legends
- Just Dance 2015

I think Ubisoft is doing a great job with apologize to all the gamers who own ac Unity. But I wonder what happens with the other season pass DLC: AC Cronicles China. Do we need to buy it separate?

Thank you for reading this Blog, please leave a comment. And sorry for my English.
