User blog comment:The Gunsmith/So, what weapons did you actually end up using?/@comment-4746180-20120412041829

It really depends on the character and on the difficulty setting. In MP and in Bronze/Silver, for an engineer, Avenger X is a hell of a weapon. Mantis X with armor piercing and damage mod is even better than a Widow for infiltrator.

A fun combo : GPS with Tactical Cloak. In Bronze, you can two-shot a Brute (provided you have the right powers and a GPS X), Banshees are taken down with 5-6 shots, 4 if you are lucky and if you are really close, you can even one-shot a Ravager. Warning, charge the GPS BEFORE cloaking, or the cloak will be interrupted before shooting.
