---

This video shows the fight on Ultra Violence difficulty (hard). For the trophy the difficulty does not matter.

This boss has a lot of health. You should go into this fight with full ammo for the BFG. There are 2 more ammo pickups in the boss fight area.
Shoot the boss with the BFG in the brain. This will stun her. Quickly switch to your most powerful weapon and shoot the brain. While she is stunned from the BFG you have a few seconds to deal huge damage. With a total of 5 BFG hits in the face and some weapon attacks you can take away over half her health in a minute.
The chaingun with the "Mobile turret" mod works great for shooting the boss while stunned. It deals the most damage.

For the rest of the fight you can use the Gauss Rifle with "Precision Bolt" mod. Just make sure you always aim at the brain. Hitting the legs doesn't do much damage.
The boss uses several different attacks:
Lasers - evade by crouching/jumoing
Melee - only used when the boss comes close to you. Keep your distance on higher difficulties. On easy this doesn't matter much.
Electric Floor AOE attack - will electrify the entire room. You must climb a pillar to stay safe. Deals lots of damage if you don't go to safety.
Plasma Rifle - will shoot at you. Easy to evade, just walk around the boss in big circles or double jump to the side when she shoots at you.
