Tip overview

Try to avoid the fire bombs, as they can do large amounts of damage to your Barricade and your Turrets.

Against everyone, just keep strafing left and right to avoid damage (especially against hit scan champions). Then aim and shoot them dead. Keep practicing for better aim and feel.

Cassie has a lot of range on Buck, so she can get in and out, fire off a few headshots, and then roll away before he can get shots off. Each counter.

Stun her, and burst her down as soon as you see her. She won't live.

Wait for her to pounce on you as she goes back as soon as she collides.
