I bet she can tear up a few zombies.
She could be a perfect turret gunner!!
just put it in her hands and she'll pull the trigger!
You can just roll her down hills and she can mow down zombies, they wouldn't catch her, We need to make her wheelchair an E-Brake though.
I suppose that she could improve the chances of Sector 7 team members of surviving. Just kidding guys but, she could be used as a distraction by rolling down a hill and shooting over their heads (because she sure as hell did not hit the target in the video).
