Propaganda Posters: 1
As soon as the mission starts, follow the red pipe and cross it until you make it to the second building. You'll find the first datapad there and a nanosuit upgrade in the other room.
Jump to the ground and proceed to the mindcarrier's location. There are a handful of ceph infantry patrolling the area. You'll also find another nanosuit upgrade in the lower floor of the building ahead. Make sure to grab it as well before clearing the ceph infantry units. Head to the mindcarrier for a scene.
After the scene, you'll have to take out the ceph infantry units attacking you. After clearing the first wave, a heavy infantry ceph unit will appear. Take it out and proceed to the main objective. While walking along the path, open your nanovisor and check the alley to the northeast. You should find a blackbox beside a lone corpse there.
Proceed to the next area where remaining CELL troops and the ceph are engaged. Be careful of the several stalkers lurking in the area. Make your way to the building to the left and climb the second floor to find another datapad and a propaganda poster in the next room as the datapad.
NY Strike datapad and CELL Bear
Proceed to the main building until you hear Claire's distress call. Head outside and you'll find some APCs and a buggy. Grab the datapad on a crate near the APCs.
Ride the buggy and make your way to the bridge. Take out the few suriving CELL troops in the blockade. Continue forth and proceed down the stairs until you exit. In the next area, jump down the series of cliffs to reach the buggy below. Make sure to activate armor mode when jumping to avoid damage. Before riding the buggy, grab the blackbox beside the corpse near the buggy.
Ride the buggy until you reach a large gate. There's a Ceph pinger and a couple of heavy ceph infantry there as well. There's an APC in the western side of the map that you can commandeer and use against the enemy forces. Head to the gate and take out the enemies. There are two collectibles in the left side of the gate. Grab the blackbox from the corpse near the gate and a datapad to the far left, next to the container vans.

Once done, go up the catwalk and follow it to reach the gate's control terminal. Activate it to open the gate. Grab a vehicle again and continue forth. Take out/ get past the enemies and follow the tunnel until you reach the next area. Proceed until you need to continue on foot. Grab the Sabot Gauss Gun from the crate beside the burning APC and proceed to the tower.
As you reach the command center, you'll have a secondary mission where you have to destroy the Tower Air Defense System to allow Psycho to land. Head to the northwest corner of the map and clear both CELL and Ceph enemies. Hack/destroy the turret guarding the defense system then destroy it by planting a REX charge. There should be some available from the crates nearby. Don't forget to grab the nanosuit upgrade as well.
Head to the eastern part to find the gate control for the left command center. After the gate is lowered, head to the left and make your way west to find the last datapad between some containers. Open your nanovisor to know its exact location.
Make your way to the southwest portion of the commander center and go up the catwalk to find the terminal that will lower the footbridge. Continue to the lift and watch the next scenes. Mission complete.
