Datapads: 5
#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.
#2. 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.
#3. Proceed to the main objective until you enter a building. You'll eventually 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.
#4. Ride the buggy until you reach a large gate. Head to the gate and take out the enemies. There are two Collectibles in the left side of the gate. Grab the datapad to the far left, next to the container vans and a Blackbox from the corpse near the gate.
#5. 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.
