The Elder Scrolls Online: Morrowind

On January 31, 2017, ZeniMax Online Studios announced a full expansion pack based in Vvardenfell, the setting originally playable in The Elder Scrolls III: Morrowind.[31] Unlike previous DLC for the game, initially Morrowind was not purchasable with crown points and had to be purchased as a separate title. The expansion includes a new class, a new trial, and a new player vs. player mode, known as “Battlegrounds”.[31] The expansion was released on June 6, 2017.[32] However, Morrowind was introduced to the Crown Store by Bethesda during the 2018 June/July sale and Morrowind is now included in ESO+ subscription.
