A grizzly’s first swat knocks you down. Down under it, the bear pins you with its forepaws and bites in bursts of two or three, holding and shaking for about a second each time, then stands over you with its head down on you. Once in a mauling it takes hold and drags you a couple of meters, and it may hook you over with a forepaw. Your breathing goes fast and shallow and the view presses low.

Lie still and it leaves sooner. Shout and it bites again; get up and run and it comes back for you. From November 5 you can hold the middle mouse button to cover, face down with your hands over the back of your neck, and its bites hurt half as much. Left mouse kicks at its face, or stabs if you hold a knife. That makes it let go of a drag and makes it angry: a black bear runs off after two hits, a grizzly only sometimes.

Better not to get there. Beside a burning fire, or with a lit torch in your hand, a grizzly displays and walks off instead of charging, unless you hit it. Your dog, if it is nearer the bear than you are, often draws it off: the bear chases and swats the dog, which yelps unhurt, and then leaves. On horseback it strikes the horse, which shies. A friend’s shout near the bear can pull it off you.

Still unproven: no check run has yet filmed the drag or the roll.
