How many grenades are you supposed to need to clear rocks?
I'm at Quarantine Stack AMEN. There's a passage there blocked by rocks.
I threw 12 regular O2 grenades and two large O2 grenades at them. Each time, the game told me I dealt physical damage - but the rocks stayed intact.
Then for good measure, I emptied a full rifle magazine into one of the rocks. Dealt another grenade's worth of damage. The rock still didn't budge.
Am I really supposed to pour that much into a single blocked passage? Or is something weird here?
