Previously scheduled to run from May 5 to May 9, the Overwatch Open Beta is getting the 24 hours of overtime. As a token of gratitude, Blizzard has prolonged the free playtime. The Open Beta will conclude on May 10 at 10:00 a.m. PDT in all regions. If you haven't tried the game yet, this is a good time to give it a shot. So far, Blizzard's new IP is looking awesome.
