Overwatch Free Weekend

Overwatch free-to-play this weekend, and you can jump in and get started playing right now through Battle.net. The multiplayer shooter is free until Monday, and this previous update has all the details:
From July 26–30, we're calling on all prospective agents: assemble your teams and dive in during the Overwatch Free Weekend on PC!

For this free weekend, we're making Overwatch's full roster of 28 heroes—including Wrecking Ball—and 18 maps available for play in a variety of modes, including Quick Play, Custom Games, and the Arcade. Players will also be able to level up, earn Loot Boxes, and unlock a variety of different customization options for their heroes.

Plus, if you decide to purchase Overwatch after test driving the game, you'll get to keep any progress that you made during the weekend—just be sure to use the same Blizzard account that you played on.
