You can do it without using the gun at all
I try using the rock but it does not work. I use the spear and nothing. Climbing equipment does nothing.
Climbing equipment can get you out of the hole just click left of the ladder.
As for the rock and stick they can be combined
I found those. Still tried the rock on the cultist. Nothin.
Safe ending is getting to the cultist without firing a shot then running away back to the car
I dunno how to get past the bear without the shot then. And when I get to the cultist and try going back it won't let me leave.
There is something i side the cabin, you just need a keen eye (and maybe a bright screen) to spot it
I saw the gun.
You dont use the rock directly on the wolf; Speara just goes on the lifted bridge; and climbing equipment just goes on the side of the ladder
