Part 2: Compound

Upon entering the compound, immediately crouch and follow the left-hand wall, moving behind crates to avoid detection and re-enforcements.

Continue until you reach a truck, stay behind it, and wait for the patrolling vehicle to pass.

Head to the marked box on the left-hand wall ahead and interact with it to disable the alarm.

Enter the door with the blue light to the right of the alarm and climb the ladder to the top.

Takedown the sniper from behind and use the zip-line to reach the roof of the large central building.

Look down the large opening in the roof and kill the regular enemy below.

Use the roof and the hole as cover (press the cover button to crouch behind walls or objects) to eliminate the other 5-6 regular enemies in the area below as they investigate.

Continue to the far end of the rooftop and kill the sniper on the raised walkway on the opposite side of the road.

Kill the elite regular and any other enemies on the ground below where the sniper was.

Head down to ground level and mop up any remaining enemies.

When all enemies are dead, proceed to the door marked with the objective marker.
