The Elder Scrolls Online: Morrowind might be scheduled for a release on June 6th, but you'll be able to get started sooner provided you play the PC version.
An Early Access program has been announced for TESO: Morrowind. Starting May 22nd, players will be able to play the expansion on live servers by purchasing the Digital Upgrade ($59.99) or Digital Collector's Edition ($79.99) on PC.
This Early Access period will provide a two week head start that will carry over all progress once the official debut arrives.
TESO: Morrowind will introduce a new class, an entirely new region of the game world, quests, items, and more. We had a chance to play a preview build on two separate occasions, which you can read about here.
