The cold wind howls around you as you trek across the endless sheet of ice, each step sinking slightly into the snow. Suddenly, something huge moves in your peripheral vision. You snap your head around — and your stomach drops.

A polar bear. Massive. And it's staring right at you.

For a moment, there's silence. Then it lowers its head, lets out a deep, thunderous growl, and starts charging.

Your instincts scream at you to run, but your boots feel glued to the ice. The bear barrels closer, snow exploding under its paws, jaws open to reveal enormous yellowed teeth. Its breath steams violently in the frigid air, and the ground seems to shake under its weight.
