EDIT: Regional pricing has been fixed! It has come to our attention that in some currencies, particularly South American, the price of the DLC is more than half of the price of the base game. This is not intended. We have submitted correct pricing to Valve and as soon as they approve it this will be fixed. I really apologize for the inconvenience.
