Blood and Rust (Mission)

 is a mission in Titanfall 2.

Blood and Rust
Head towards the marked location where Militia members are asking for assistance. Help them on your way, and get ready for a fight - there are 6 Titans to take down in this section. Once inside the sewers as marked on the map, you'll find a new Titan Tone. Keep pushing into the control room, and defeat the guards, Titans, and drones here. BT will ask to separate so that you can open the Flow Regulation Gate. Exit and follow the marker into the control room to do so.

When the gate is opened, the room will start emptying of toxic gas. Head towards the marked location to find some surviving militia members. Take down the IMC guards here, and keep moving through the level. Eventually, you'll come across a horrible group of IMC bots known as the Stalkers. These creatures will rush you, latching on and exploding, so you want to take these out earlier rather than later.

Exit after saving the troops and take down the room of IMC scouts. You'll then be tasked with shutting down the toxic sludge in this area. After you do that, you'll be able to progress and rejoin BT. Take down the guards, ticks, and scouts as the shutdown is completed, and you'll face your first real boss - Kane, an Apex Predators affiliated Pilot with the IMC. Take down his allied Titan, and then use the pillars in this area to avoid fire. Take him down and defeat him. Grab his helmet.
