"Meet Ana, a battle-scarred agent who would do anything to protect the people closest to her.
After hanging up her rifle for over seven years, one of Overwatch’s founding members is returning. Introducing Ana—a battle-scarred veteran who supports her teammates from a distance using a unique and highly specialized collection of weapons.
Ana’s primary weapon is her Biotic Rifle, which fires long-range darts that can restore the health of her allies or deal ongoing damage to her enemies. Meanwhile, her Biotic Grenade is perfect for a close-quarters clash, because it simultaneously heals teammates and injures foes caught in its small area of effect. (Affected allies will also receive a temporary increase to all incoming healing, whereas affected enemies can’t be healed for a few moments.) And if the battle starts to get out of hand, Ana’s side arm can fire a Sleep Dart, knocking her adversaries’ unconscious.
Plus, Ana’s ultimate ability, Nano Boost, transforms teammates into super soldiers, granting faster movement, increased damage, and resistance to enemy attacks."
