If you live in North America you will be able to play Overwatch as of May 2nd, 2016 at 7pm EDT
There's some really good news today for American Overwatch fans (that means you too South America). If you live in the Americas you will be able to play the game 1 day earlier than the advertised Overwatch early access date! According to the official Overwatch blog, Overwatch early access will start worldwide on May 2nd, 2016 at precisely 7 pm EDT.
That's right, you didn't read it wrong. The Overwatch open beta will be available to early access members on May 2nd, 2016, tonight!
Overwatch will be available to all players at the same time. Chances are the open beta will serve as the ultimate stress test for Blizzard's servers...
The information on Overwatch's early access activation times also came paired with the activation times for Overwatch's all access beta times. These will start at the exact same times as the above map, but with the all access dates of May 4th and 5th respectively.
The world will have more than enough heroes come May 4th, but more are undoubtedly wanted for the true release of Overwatch on May 24th.
