While previously the beta was open this week to those who had preordered the full version, anyone can hop online and join the fight now through May 9th. There's a pretty large spread of content to wade through too, with all 21 heroes available upon download and Quick Play, Play vs. AI, Custom Game and Weekly Brawl modes on tap for maximum carnage. If that's not enough, you can hone your craft with Tutorial, Practice Range and Practice vs. AI modes as well.
As far as duking it out with other players, there's a selection of 12 maps and four multiplayer modes. For Assault, you can head to Hanamura, Temple of Anubis and Voskaya Industries. For Escort games, there's Dorado, Route 66 and Watchpoint: Gibraltar. If you're into Assault/Escort mode, you can hit up Hollywood, King's Row and Numbani. Lastly, for Control games, you'll be exploring Ilios, Lijiang Tower and Nepal.
The full version of Overwatch comes out on May 24th, so if you're interested in previewing it ahead of the end of the month, you'd better jump on it fast. It should make for a good weekend play.
