Hello,

I bought "Batman Arkham City" (PC Game). Could you please advise how to register my copy?

I would also like to buy other DLC's of this game, where can I buy them?
 
Solution
during installation or sometimes when playing the game for the first time, it usually asks you to register.
also, batman is... steam or GFWL? you should be or it is already registered.
unless that is a pirated copy
