So I've found a couple areas where you can't kill anything - it always shows IMMUNE or RESIST So I end up always leaving the area wondering if its ment to restrict the areas But then I find this cave on the side of the map with a giant Hollow Knight with the same set up: Over Powered Level unknown "??" and all bullets cause "Immune" to be shown (all weapons and supers and grenades) But I did find 1 way to take care of business https://www.facebook.com/photo.php?v=908945202455161&l=2515357655593768584
