Make your way to System-X | The Root of All Evil Crysis 3 Guide

Climb the elevation to the right and go straight ahead. When you approach a road block, jump over to the other side. On here, on the building, you will find a poster 1/1.

Jump down now and go straight ahead. In the first basin to the left, near the corpse, you will find a Blackbox 1/3.

As you go straight ahead, you will encounter an enemy patrol. After you walk around them, you will reach a forking road (some 180 meters of the destination point). Turn into the tunnel to the right, where you will find another Blackbox 2/3. There also is an ammo crate here.

Once you leave into an open area, near the CELL headquarters, turn left, while remaining atop the elevation. Walk over to the left side of the building and jump down from the elevation. On your way, you will walk past a turret, which can be reprogrammed.

Ahead of you, there is an empty container, and a sewer entrance, shown in the screenshot. Right next to the entrance, there is a corpse with a Blackbox (3/3) on it.

At the end of the sewer, disarm a mine that has been blocking further passage. After you gain access to the base, climb up the stairs. The elevator that you need to take to get to the core, is at the far end and is guarded by a mobile turret that cannot be reprogrammed. You need to squeeze behind it or destroy it.
