Centurions like to chuck smoke grenades in my squad's face like punks. While it definitely puts a damper on my visibility, it does not seem to have an effect on the Centurions themselves. The only other subjects left to subject to smoke are my squad mates.
Can my squad mates see through smoke? Does it affect them in any way, or do they ignore it and continue to suppress the enemies with their uncanny combat skills? If they can see through the smoke, why don't I get a cool pair of smoke goggles too?
