Android robots randomly die instantly when you attack them with electric damage. It doesn't matter if I change their health with "Mech enemies HP" sliders with damage floor mod. Luckily this doesn't happen to Mechs although their arms break quite easily compared to torso(but still durable).
It makes certain sense since they are robots, but I'm still not a fan of CDPR choosing "instant death" mechanics. I mean they are military grade robots and those EMPs are caused by small caliber bullets.
It would be nice if EMP deals huge, but a fixed damage to, or rather cripple the robot instead of destroying it immediately.
