The Overwatch website announces that the early access period has concluded for the Overwatch open beta, and testing of Blizzard's multiplayer first-person shooter is now open to everyone. Testing will continue until the 9th, at which point it will go offline for a couple of weeks to pave the way for the game's official launch on May 24th. This previous post has details on how to participate, including a FAQ which notes that all progress and unlocks from the beta will be wiped before the official launch. If you want more details on the game, head over to the Overwatch website. In short: "In Overwatch, you control one of several heroes in competitive 6-person team shooting matches. Battle over objectives, take down the other team, and achieve victory."
