Post-release Modules
Turbine releases major content updates as modules, named after the module concept in the pen-and-paper version of D&D. Additional content was released between modules as "updates." Responding to the player feedback that the interim updates do not provide enough new content, the development team stopped releasing interim updates starting with Module 5. The developers instead focused on creating larger modules. Prior to the launch of DDO: Eberron Unlimited, there was a 10-month content gap.
On June 9, 2009, the official D&D Online website announced that Dungeons & Dragons Online would convert to a subscriptionless "free to play" game for players in North America, under the new name Dungeons & Dragons Online: Eberron Unlimited. The level cap would be increased to level 20 (also the standard level cap in the tabletop Dungeons & Dragons) and Free users would have access to the majority of game content; some features would have to be purchased with Turbine points or unlocked through play. There would be VIP access with additional features available, as well as free Turbine points. Closed beta registration opened on June 9, 2009. The game and contents were free to download on September 1 for VIP members and September 9 for the general North American public.
Turbine presented its new "Menace of the Underdark" expansion module at the PAX East convention in April 2012, before releasing it in June. The expansion increased the maximum character level and added the druid class.
