Cabela's Survival: Shadows of Katmai

Occasionally, an animal will latch onto you with jaws and try to make a meal out of you. When this happens, get them in the cross-hairs and take them down. Unfortunately, latching happens very rarely without coercion. While I have read that cougars can latch onto you, I was never able to get one to do so during my hard playthrough. That said, I did have quite a bit of success with the White wolves. Better yet, there’s a very nice place to farm these latch kills: During the third or fourth (maybe fifth) chapter, you will be tasked with gathering some vaccine samples. At the beginning of this little quest you will deal with a good number of wolves, several of which are white. Kill off all the non-White wolves. Let the White ones latch onto you by just standing there. Once they do, kill them. You can reload the checkpoint as necessary to unlock all of these latch trophies at the same time.

If you're still having difficulty with this trophy and still don't have it after your hard play-through, try lowering the difficulty to easy, so you don't die as fast.
