Note: After selecting this mission, you can no longer do any side missions.
Head down the destroyed street, inspect the vehicle and slide down the tunnel. From here, make your way through the area with destroyed houses, from where you can expect resistance from enemy troops.
Note: These enemies may *randomly* drop the Banshee Weapon. Restart the mission if it doesn't spawn.
Continue through a large building at the end of the area, head down, overhead someone saying "get to the annex", and head around the corner. There are various enemies in the big street up ahead, so naturally clear all of them first before proceed.
Note: There's an armory with an equipment upgrade at the end of the street; double jump to reach the door.
Proceed until you reach a shop, where you'll meet very heavy resistance from enemy troops. Destroy the incoming bot, then throw out all your Seekers and snipe several soldiers in the distant buildings.
Note: You can find the KBS Longbow Weapon laying just outside the shop.
As you press onwards, stay on the lookout for ammo crates and seeker crates, and use all your seekers everytime you can.
You'll reach an area with churches at the far end of the first zone. Employ drones and seekers to take out most enemies and snipe the rest. Move past the scaffold into the street, hurl a few grenades at the enemies there and then, at the end of the street, double jump up near the ladder to reach the annex.
Equip your shotgun (Type-2, for example) and climb the building, shooting anyone that stands in your way. Enter the Jackal at the top to board the ship.
Note: You can find the Titan Scout Weapon in a container just in front of you, or alternatively against some white boxes nearby, just beyond the container. You can also find the Oni handgun inside the container, and the Erad in the left corner up ahead.
Clear the area of enemies and a big mech will show up. Aim two rockets at either its left or right side and destroy it with the bazooka laying in the nearby container. If you want to get the C12 Trophy, destroy both arms with rockets, restart the mission, destroy an arm and perform a left rodeo, restart the mission, destroy an arm and perform a right rodeo.
Head up the elevator and follow your crew along a spectacular travel path, but ultimately linear one. Set the device at the end, continue and ultimately hack one of the bots to defeat the Admiral. If you want the You Know Nothing Trophy, *immediately* kill the Admiral without him saying his speech.
