Video Walkthrough:

Begin controlling a minigun on a helicopter; it has unlimited ammo and does not overheat. Focus on hitting enemy gunners and helicopters.

After entering the sandstorm, cutscenes will trigger.

Once in control, follow the road. The game will explain basic controls.

Continue until you reach a cliff edge, then head right.

Move over obstacles and rappel down at the metal posts on the cliff side.

Proceed down the road, listening to character dialogue. Sprinting is not possible for several hundred meters.

Crouch under a truck to enter an open area with military vehicles.

INTEL 1/2 (Konrad Confession Letter): To the left of the area's entrance, on the chalkboard next to a humvee, on the back of the truck.

After dialogue and a short cutscene (a non-interactive cinematic the game plays automatically), you will face the first enemy infantry. You will automatically be placed behind cover (press the cover button to crouch behind walls or objects).

Wait for the option to shoot the sand-filled bus above the enemies' heads. Shoot it, then eliminate the single enemy to the left.

Move up the path and take cover behind crates. Shoot red barrels to eliminate some enemies.

Be aware of two more enemies approaching from the dunes to the left.

Further up the path, you will encounter a bus with heavy fortifications. Aim at the pass and press the indicated button to have your team clear it.

You can switch your pistol for an enemy SMG.

Proceed through the cleared bus and take cover outside. Hold the indicated button, move the cursor over the target, and release to have your teammate dispatch the target.

Move forward a few meters and find cover. Clear the next wave of attackers and move through the shipping container.

A cutscene will play. Immediately find cover behind the nearest car.

You will be introduced to the "slip out" feature, allowing you to move between cover without leaving it. Press the cover button again when reaching new cover, as your character will not do it automatically.

Move from cover to cover, staying parallel to the machine gun. Once behind it, pop up and shoot the red tank to eliminate the gunners.

Quickly look left to prepare for another assault as remaining soldiers may charge.

Move forward a few meters for a cutscene and a change of location.

Equip silencers on your weapons and eliminate soldiers from a distance.

After the initial group is dealt with, another group will emerge from the plane's tail and wing.

If pinned down, use RB to mark targets for your squad.

Head into the back of the plane. Two enemies will approach from the stairs.

INTEL 2/2 (Damaged Black Box): In the back of the plane, just before the first flight of stairs. The intel is a red box on the ground to the left.

Pick up a shotgun for upcoming close-quarters combat (CQB).

Head up the stairs and use the stairwell for cover while eliminating enemies.

Continue down the plane, taking out any opposition.

In the area with seats, have your squad mate throw a flash grenade. Start shooting.

Cross the room to a hostage situation. Shoot the enemy holding a gun on the friendly soldier, then engage the other soldiers. You will be in slow-motion.
