Dealing with BTs

Hey all,

So have been playing DS for a while now around 35hrs in and I am currently at the place where my BB is in recovery and I gotto manage without him in the mountain area.

The game is truly amazing but I am having a hard time dealing with BTs. What is the best approach when dealing with them? Holding my breath and crouch till they are gone? Use hemantic grenade or non lethal rifle?

Dealing with MULEs are much easier in my opinion but these BTs are always giving me the creeps lol.

Also should I expect more BTs during timefall?

Thanks!
