Datapads: 3
#1. After destroying the tower using the ceph Bolt Sniper, turn around check the hills to the northeast of the map. You'll find a datapad there.
#2. After clearing the marsh of enemies, continue to the overpass. Here, you’ll hear Psycho mention about a CELL supply drop ahead. Head past the overpass and continue past the pond to spot to CELL troopers and a container. Open it to get a nanosuit module upgrade and a datapad on the ground.
#3. Once you’ve reached the train yard, proceed to the north past the deployed turrets overhead. The datapad is found in the submerged maintenance tunnel under the tracks.
