How do i get exclusive content code Assassins creed 2?

so 2 months i both the normal game and i played much time.So one day i found that in exclusive content you can get 3 Templar lairs that kinda continue the story so i cheked my game and Becose its a normal(not black or white or master edition) there is no code inside and i keeped surching for someone that can give me code or tell me how to cheat it Excuse me for my bad English.And Thanks

I don’t know what to tell but to keep asking people cause if people already used the code then.They can’t give you it since it’s tied to their account.But even then, the Black Edition came with a code for 3 maps, the Master came with 2, and the White only came with 1
