So use plasma?
The burst lasers can do it. You must select the "inertial impact" experimental modification on them with the main modification you wish. Enjoy and... Good luck... really. I tried them and it was frustrating to me, they fail many times on medium and long ranges, but it´s the price of the definitive weapon.I suggest adding mods that allow bullets to do better shield damage, and lasers to do better kinetic damage. I'm not a fan of this silly weapon switching in the middle of a fight. It feels more like Unreal Tournament and less like like ED
