You start as Chris Redfield in a snowy mountain range. Your objective is to reach a communication tower. Follow the linear path, dealing with Fenrir (infected wolves). These enemies are fast and attack in packs. Use your shotgun if you have one, or aim for their heads with the rifle. You'll encounter a few environmental puzzles involving climbing and traversing ledges. Keep an eye out for hidden ammo caches in the snow. Eventually, you'll reach the communication tower. Interact with the console to trigger a cutscene and switch back to Jill.
The Fenrir are a significant threat due to their speed and ability to pounce. Try to keep your distance and use weapons with good stopping power. If they get close, a well-timed dodge can save you from taking damage. Explore the snowy paths thoroughly, as valuable rifle ammo and grenades can be found off the main route. The climbing sections are generally straightforward, requiring you to press the action button at the right time to ascend or descend.
