You don't know how long you've been trekking on the snow-covered mountain...
You feel you're about to freeze when a campsite appears in the far distance.
It might not be the mission location as marked on the map, but...
If you don't get to warmth soon, you will probably lose a couple of toes.
...?
Actually, the light in the distance seems a little too bright to be given off by a campfire.
Could it be...
As you suspected, what lit up the campsite was not a campfire but an explosion.
Like all the refugees you've met before, these poor drifters are defenseless against the Corrupted.
Understood!
