At Blizzcon moments ago, Blizzard announced a new deal for free access to Diablo 3. If you sign up for 12-months of World of Warcraft via the WoW season pass you will get Diablo 3 for free. You can still be billed monthly, otherwise you'd be forking over almost $200 at once. Not only will you get instant, free access to Diablo 3, but you'll also be guaranteed access to the next World of Warcraft expansion's beta.
To sweeten the deal Blizzard will also be giving gamers who sign up for this deal an exclusive mount, Tyrael's Charger.
You can sign up today.
