Mission 4: Safeties Off

Datapads: 11

Blackboxes: 4

Propaganda Posters: 1

You have to avoid the searchlights and fight your way through the swamp towards the objective. Once you get near, a secondary objective will trigger. Open your map to know it's location. Head there and hack the first turret to the west so you can climb up the ledge and enter the building to find an ammo cache and nanosuit upgrade module inside.

Proceed to the secondary mission marker and disable the second turret. Kill the two guards and find several Datapads in the vicinity. Three will be near the helicopter wreck while the other three is found in the building ruins nearby. There are four datapads here, one will be needed for completing the secondary mission.

Secondary Mission Datapads

Proceed to your main objective and you'll spot a heavily defended building, beside the chinese structure/arch. There are also Collectibles inside. Proceed there and find the Propaganda Poster in the lower floor, on the wall facing the archway. If you scanned the area, you would have probably tagged and recorded it (a natural occurrence for propaganda posters if you noticed) so if it isn't highlighted in your hud, it's already recorded. Proceed to the third floor to find a nanosuit upgrade module and another datapad.

After getting the Collectibles, use the zipline nearby then follow the straightforward path until you kick a door open and encounter a close scene with System X/ Alpha Ceph. There's a downed CELL trooper ahead by the toilet. Grab the Blackbox from him.

Blackbox #04-01

Jump to the ground and take out the Ceph infantry units. These are a bit tougher than your ordinary CELL foot soldier but they shouldn't be that hard to deal with. Head to the Ceph Mindcarrier while clearing the enemy forces. Ammo is scarce so make sure to pick up and use the Ceph Pinch Rifles or any weapons you can find. After making it to the Mindcarrier, open your nanovisor to tag the datapad inside the building, past the mindcarrier. Grab the datapad on a shelf inside.

Mindcarrier Datapad

Continue to the main objective and you'll see some CELL troops getting incinerated. Pull up your nanovisor here and continue walking forth. You'll find a nanosuit upgrade inside the building to the left. Past that is a CELL weapon cache. You can pick up another datapad on the table in the building ahead, next to the ammo cache and a black box from a CELL corpse in the street, right outside that building.

Head to the blue gate to encounter a scorcher. Kill it then continue. After going through the building, you'll be notified about a nearby Ceph Pinger as your secondary objective. Get into recommended distance and hack it to activate it. Once clear, continue to your next objective.

When you're near the pit vicinity, you'll find more Ceph targets here. Kill them all and find the controls to lower the pit gate. Head to the elevator and you should be able to pick up another Blackbox from the corpse outside the elevator. Just open your nanovisor to spot and tag this.

Blackbox #04-03

After picking up the Blackbox, ride the elevator with Psycho. After reaching the laboratory, continue to the observation window and open your nanovisor. You'll be able to locate and tag the last three remaining Collectibles. Go downstairs and find the fourth blackbox beside the doctor. Go through the curtains and move around the to the right to find another datapad. Continue downstairs and you should be able to pick up the last datapad and a nanosuit upgrade on the wall in the same room.

Open the next door and proceed further in the facility with Psycho until you're able to find a cradle. Watch the next scenes and the mission will be complete.
