All the p2p dungeons from DDO are now free! Enjoy the best MMORPG for dungeons
Dungeons & Dragons Online (NOT Neverwinter)
You can only see lots of other players when you're in safe areas. Every dungeon and wilderness is instanced. This means the adventure always belongs to no one but your party! Up to 6 players from traditional D&D classes such as Fighter, Cleric and Bard can group up to take on a great variety of missions.
Quests are no easy feat. They will require great cooperation There is nothing like “kill X monsters” or “grab Y items”. New adventurers might have to delve deep into the sewers to find out what is wrong with the waterworks to reestablish the city's water supply in a 4-part quest line.
Meanwhile, veterans seek out ways to solve a number of puzzles in a vast, lava-filled fortress to only then get teleported hundreds of miles above Stormreach, where a great red dragon bides his time before attacking the city. But in this 12-players raid, the party must split into three smaller units in order to break the barrier crystals at the same time — or they will regenerate. Fail more than once and your party will certainly be out of resources for another attempt.
Don't get me started in the glorious variety of content. Well, if you insist... Explore the home of the giant king Stormreaver, fend off a Lich and his cult deep within the Orchard of the Macabre, free citizens from the grasps of a Mindflayer before more of them are twisted into aberrations. You don't even have to stop at the main realm of Eberron — become strong enough to travel into the Forgotten Realms.
You can do all of it for free! I mean, only if you use the promo code “HAPPY14”. Most of the areas from these quests would usually be pay to play buy either purchasing a pack including multiple of them or becoming a VIP to enjoy everything for a monthly fee. However, DDO's developer Standing Stone Games is holding this promotion until August 31st, when the code stops working. But you do keep all current content forever.
