The sign-up questionnaire can be found on The Elder Scrolls Online website here. The questions include guild affiliation, previous MMOs played, previous Elder Scrolls games played, play style, and a DxDiag file from your computer.
Gamers who are selected for beta testing will get access to early versions of the game. Bethesda even mentioned that the first beta test will begin "soon." Of course, "soon" in the MMO world is very relative.
To celebrate the big announcement, Bethesda also released a big trailer for the upcoming MMO. The trailer, called "The Alliances" is a nearly 6-minute cinematic tease for ZeniMax Online's vision of a multiplayer Elder Scrolls experience.
