Dirge of Cerberus: Final Fantasy VII/Chapter 5 - Manor of Despair

Boss: Black Widow
There are several ways of bringing this boss down, and all of them are pretty equal in terms of best strategy. One way is by using a limit breaker and give far worse than you get - at least you'll save on bullets. Another way you can do this, which is slightly superior in terms of tactics, is to shoot it from afar. Keep a lock on it and strafe around it, all the while shooting it - it's recommended that you use the machine gun or Cerberus with the normal barrel, as while the rifle does superior damage, its reload time is very slow, which is not good when fighting the Black Widow.

Most of this boss' attacks aren't that bad, except for the laser. You can tell that the laser is about to go off by the glow at the tip of the Widows' weapon, so dodge and duck to keep away from it - it can deal some serious damage.

Sometimes the Widow climbs up walls and onto the ceiling, all the while shooting at you - keep shooting it for dear life, as if you knock it down, it'll be on its back and its belly is its major weak spot. It's recommended that specifically for this you change to a rifle with your most powerful barrel - you might not get that many shots in, but every shot you give to it while it's bearing its weak spot is a critical hit. In other words, loads of damage for the Widow.
