Awp headshots deal 400hp at least, x 100 is 40000hp, easily enough to kill more than a few zombies. Imagine that in a tube where most players crawl in without moving their headshot hitboxes, with more knockback then a shotgun. If we could simply pick them up again that would be perfect, but if they become purchasable they would need serious reduction, and the auto-snipers would have to be nerfed even more.
