New C4 safe zones on Inferno
After the CS:GO update for June 16, the C4 damage on Inferno was increased from 500 to 620. In this regard, the safe zones have been significantly shifted.
A Reddit user named ZaNe_ClaNe showed the positions that can be considered safe with a given amount of health points. On the Inferno minimap, he outlined four zones: 100+ HP damage with armor, 50 HP damage with armor, 25 HP damage with armor, and a safe radius.
