After publicly unveiling Overwatch during Blizzcon 2014, the public video demo shows 12 heroes - all with unique skills and fighting styles - battling through multiple environments. The design team wanted "limitless diversity" in the gaming environment, which will continue to need adjustments during internal testing - and when the beta opens up next year.
Here is what Bill Petras, Blizzard Art Director said: "We want to have a world of diversity, so that's something we're really excited about. Looking at all the heroes, there is a lot of iteration back and forth when I work with the heroes."
The Overwatch beta will begin 2015, but interested gamers can now sign up for a test of team-based shooter. Blizzard doesn't have a scheduled release date for the game, and will continue to work to ensure the product is well polished before release.
