From the official Deadlock Steam page:
Armed with an heirloom revolver and a spirit lasso, Holliday's investigations have led her to New York... and when she finds the killer she's looking for she's bringing him in dead, not alive.
In-game description:
Holliday depends on her skills as a crack shot, shooting things she's bounced into the air. With good aim, she can lay out heavy damage. Her movement skills let her isolate her enemies or beat a hasty retreat.
