BioWare has teased that Dragon Age: Inquisition will feature four-player cooperative play, with the developer teasing on the official FAQ for that game that players will be able to game with others on new missions given by specialists, acquire gold and loot, craft new items, as well as unlocking new characters, weapons, potions, armor and more.
The developer does have a goal, which "is to make a fun dungeon-crawling experience that you can play with your friends. There will be no pay walls in Dragon Age multiplayer. Everything is accessible with gold coins. You can use premium currency, but you don't have to." Better yet, Dragon Age: Inqusition's multiplayer can be played without any effects on the single-player side of things, and vica versa. The cooperative story is completely separate from the single-player campaign, with items from the multiplayer side of things not carrying over to the single-player side.
"We wanted to make sure that the two economies are separate, which will allow a stronger progression in both SP and MP," BioWare says. They continued: "If you play Dragon Age multiplayer, you will learn how each class plays a different role in combat, how different skills work, and how your party composition can give you a tactical advantage on the battlefield. This knowledge is transferable to SP, but items are not."
