We kinda accidentally figured out how to survive tho. Since it's a 380 surrounding the player. Of the team stays together/heavy armour/don't move around too much (Ragdolls happen) you should be able to just walk right through it
This is Helldivers 2. I expect a newly released grenade will bounce off a SH-32 Shield Generator Pack from the inside as I throw it. It would steal from the helldiver experience if things worked as intended.
