Blizzard revealed a new hero for Overwatch. The new hero is called Ana and she is a support sniper.
And that’s her description:
Ana’s versatile arsenal allows her to affect heroes all over the battlefield. Her Biotic Rifle rounds and Biotic Grenades heal allies and damage or impair enemies; her sidearm tranquilizes key targets, and Nano Boost gives one of her comrades a considerable increase in power.
