Credits to szu1985 for finding it first.
This BF4 Easter Egg lets you hear a loud Yeti Scream on Golmud Railway:
- Go to the Golmud Railway map and find this rock on Russian spawn side:
2. Go around it and step into the shadow:
3. Turn around and watch the mountains in your back and go backwards, if you go far enough it should trigger a bright light on one of the mountains:
4. All you need to now is shoot it, you won’t reach it with a sniper shot so use an SRAW and aim towards the light until you hear the yeti shout and the light goes off.
