Zaeed: The Price of Revenge

Zaeed will request your assistance on Zorya in the Faia System. You're tasked with assaulting a refinery that has been seized by the Blue Suns. Your main objective is to kill the Blue Suns' leader, Vido Santiago, with saving the workers as a secondary goal.

The Blue Suns forces include Pyros, Heavies, Troopers, and a few FENRIS. Some of these have powerful Missiles and can damage armor quickly. If possible, keep up your shields and barrier if using a Biotic or Tech user. After clearing the first few waves of enemies, you'll arrive at terminal controlled bridge, and upon accessing the controls, Zaeed will inform you about his past in forming the Blue Suns with Vido.

After killing the Blue Suns passed the southern gate, you'll be given the option of taking a Paragon or Renegade option of saving the workers, or heading to Vido directly. Taking the Renegade route will always secure Zaeed's loyalty, while the Paragon option will require Charm check later in the mission. If you fail this Paragon check, Zaeed will remain unloyal through out the game.

On the Paragon path, you'll enter the burning refinery. Your goal is to douse the flames by accessing the fuel control stations to lighten the gas pressure. There are three in total: one near the stairs, the second bthe pipes on the left, and the final one on top of a catwalk on the upper level.

If you take the Renegade option, you'll instead get into another fight with more Pyros and Heavies. Use the standard method of keeping in coaver, and pop out to break down any armor and shielding before going for a kill shot.

The two paths will converge for a fight in the refinery's core. The Blue Suns will constantly send reinforcements, so make your kills as fast a possible before you are overwhelmed. They will also release a YMIR Mech, which should become the top priority target. After clearing out the room, head outside for the final scene.

Taking the Renegade option will allow Zaeed to take vengeance against Vido. If you selected Paragon, Vido will escape and a steel beam will collapse on Zaeed. Depending on your progress through the game and amount of Charm, you will have either two or three options. Mainly, you'll want to try and use Paragon to convince Zaeed that the mission comes first. If you're completing this mission very late in the game, after the Omega 4 relay, you can even kill Zaeed here.
