Part 3: Bunker

Enter the base and follow the ramp to the bottom.

Crouch and make your way to the far doorway, performing chained takedowns to eliminate guards in the hallway. Aim to chain kill 4 and use a shuriken for the 5th.

When a heavy gunner enters the door at the end of the hallway, throw grenades and shoot his head while backing away and getting into cover. Damage him until he falls.

Continue down the left hallway and climb up to the catwalk indicated by the objective marker.

Follow the catwalk to the left and around the corner to the main room.

Tag all visible enemies before dropping down: a molotox and a regular on the upper walkway, two regulars on the ground, a stationary guard at the alarm, and another patrolling.

Wait for the patrolling guard to walk out of the room and towards the alarm guard.

Jump down, land on the two enemies below to kill them, and then take down the patroller.

Shuriken the guard at the alarm and run to disable it.

Clear the rest of the room, which includes an elite regular, 4 regulars, a charger, and any remaining tagged enemies. If the alarm was triggered, you'll also face 2 heavy gunners/flame throwers and additional regular units.

Head to the far side of the room. Collect ammo, body armor, and health from desks near the exit if needed.

Continue through the next door once Spider unlocks it.

Follow the walkway to the right and up the first flight of stairs.

Note the brown hatch on the missile in front of you; you'll need it later.

Continue along the walkway to the objective marker and enter the small office with computer consoles. A scene will play.

Defend the computer console from a group of enemies entering the silo from walkways and the center. Keep an eye on the mini-map and eliminate close threats quickly. Expect 10 regulars and a heavy gunner.

After the scene, sprint to the objective-marked hatch and interact with it for a scene. If you are too slow, you will have to fight a pair of heavy gunners.

When you regain control in the cave, cross the rocky bridge to find Dr. Carlyle’s Notes, your first collectible.

Make your way through the cave to the exit objective marker. A short scene will play.

Crouch and work your way across the open field, avoiding the Blood Dragons. They can hear you but not see you unless alerted (yellow) or attacking (red).

At the far end of the area, pilfer three cyborg corpses for their hearts.

Throw a cyber-heart past the dragon blocking your path to lure it away.

Continue down the hill, avoiding dragons, until you reach the designated vantage point with the objective marker.

Toss a cyber-heart through the energy shield to have the Blood Dragons destroy the guards inside with their laser eyes.

Enter the bunker inside the energy shield. Grab the C4 and bow.

Go around the back of the building, equip the cyber eye, and tag the enemies in the base below.

Choose one of the following options to free the garrison:

• Option 1: Head up the hill behind and to the left of the base to find the shield generator. Blow it up with C4 to disable the mega shields, allowing Blood Dragons into the base.

Option 2: From the generator hill, ride the zipline into the area. Work your way to a nearby console and disable it to bring down the mega shield and allow Blood Dragons in.

Option 3: Run into the base and kill all enemies yourself.

Once all enemies are dead (and any Blood Dragons you used are dealt with, e.g., by tossing a cyber-heart out the gate), a scene will play to indicate liberation.

Make your way to the objective marker and interact with the control panel for another scene.
