Do you need a piercing mod equipped to shatter the Atlas Mech's canopy?
I've shot the canopy on the Atlas with the sniper rifle several times, and have not seen the canopy shatter. Do you need a piercing mod attached to you weapons to shatter the canopy?
Solution 1:
no. all you need is a higher powered sniper rifle. here's a video: http://www.ign.com/wikis/mass-effect-3/Atlas_Mech
