Curiosity kicking in. Does this perk only work with grenades and other explosives or does it work with the likes of Arty airstrikes as well? I know Guardian Angel works only for air strikes and gives you an audio warning so they do have different purposes but yeah, just curious. I always just assumed one was for airstrikes and the other was for explosives. @Amerika perhaps you know?
Unshakeable perk
Unshakeable works against all explosives, including airstrikes. Good luck testing it though
I don’t think there is a control result besides death. Everything else has too big a variable on distance from epicenter.
I didn’t want to test it really I was just curious, because my two favourite bushwhacker cards I use on different maps - one has guardian angel and the other has unshakeable but I only use the guardian angel one on Chapel because I thought unshakeable didn’t work against air strikes.
But it occured to me I always hear airstrikes coming, don’t think I’ve ever really been caught out by one not knowing it was coming any way, so I think I will avoid my guardian angel card from now on.
It’s supposed to work on all explosives in the game. Which should not only include merc abilities but also generator/bomb explosions. However, what it is supposed to work with and what it actually works with could be two different things 
So what does this mean for the Vassili P92 @Amerika? I have this card in red swiss gold. It has unshakeable and guardian angel. Does that mean if an Arty airstrikes me cross map I take a collective 40% less damage since both give 20% less or still only 20%?
Someone asked this already and it was answered as they do actually stack.
Imagine Skyhammer with unshakable, guardian angel and fail safe… Running in enemies throws airstrike on himself and surviving it
