All you have to do is log into your Battle.net account and sign up through "Your Game Accounts" – or, if you're a non-Battle.net person, create a new account and you'll have the license automatically. You could be enjoying a limited sample of Diablo 3 in no time!
The demonically-besieged world of Sanctuary needs heroes. Now you can join in the apocalyptic battle for FREE via the all-new Diablo® III Starter Edition. Available exclusively via Battle.net®, the Starter Edition allows you to fight your way up to the Skeleton King boss in Act I, and advance all the way to level 13, without having to purchase a copy of Diablo III.
You can get the FREE Starter Edition in any of the following ways:
· Log in to your existing Battle.net account at http://www.battle.net, and sign up for the Diablo III Starter Edition through the "Your Game Accounts" section.
· Create a new Battle.net account here and the Diablo III Starter Edition license will be added to your account automatically.
· Grab the Diablo III game disc from a friend, install the game, and then log in with your Battle.net account. The Diablo III Starter Edition will be added to your account automatically.
Note that certain game features are restricted on Starter Edition accounts. Any progress and achievements you earn while playing the Starter Edition will automatically carry over if you decide to upgrade to the full version of Diablo III, and the Starter Edition restrictions will be removed.
For more information and a full list of restrictions, check out the Diablo III Starter Edition FAQ.
