 In late 2009, EA began implementing online passes in its games as part of an initiative known as "Project Ten Dollar"; "Mass Effect 2" used an online pass to allow access to bonus content through its "Cerberus Network" system, while "Dragon Age Origins" came with a code that could be redeemed to download its first major DLC release, "The Stone Prisoner", for free, as well as an exclusive armor set.In May 2010, EA announced that beginning with "Tiger Woods PGA Tour 10", all future EA Sports titles would require the use of online passes to access multiplayer.In mid-2013, many publishers began to phase out online passes; in May 2013, Electronic Arts announced it would, due to customer feedback, discontinue its future use of online passes in upcoming titles, and retroactively remove the online pass requirements from existing titles.
