 If a player does not have an unused online pass (such as when buying a used game), the player can either purchase access via their console or can access a limited trial of the game's online content.In some cases, a game may similarly come with a code that can be redeemed for free downloadable content and other items released upon or shortly after the game's launch, such as "The Stone Prisoner" DLC and the Blood Dragon armor set for "Dragon Age Origins", the "House of Valor" quest for "", and a package of 20 additional songs for "Rock Band 2".Alongside downloadable content, online passes add an additional revenue stream which can be used to make up for profits lost through second-hand sales, and encourage players to buy games new at retail so they do not have to pay extra to access the game's full content.
