Since I just found the Widow I thought it would be appropriate to buy the Black Widow for a quick follow-up. The BW is purchased at the Spectre Office on the Citadel from Spectre Requisitions. It costs about 250k on the Citadel or 275k on the Normandy once you've visited the office for the first time. The Black Widow does damage on par with the Mantis (a bit less) while having 3 shots in the clip and 16 in reserve; it also fires faster. The Black Widow is your sniper rifle of choice if you like the power of the single-shots but want the margin of error of the semi-automatics. When you consider that head-shot damage is often overkill anyway this becomes a very powerful weapon, especially on lower difficulties. You can find my Engineer Insanity playthrough on my channel; feel free to comment/like/sub. I really appreciate it.
