I know the gauss build is overdone on this mech but i though i would like to share my build, 30dmg is enough to kill a mech with a headshot (you need at least 27dmg) so i have been using this build to go after the headshot achievements Modules: Advanced zoom Radar Deprivation Gauss Cooldown (-12%) Gauss Range (+10%) Weapon Stats: 32% Gauss Cooldown (Quirks, Elite mysteries and pilot skills) 726 Optimum range and 2178 max range 2240 projectile speed
