Part 36

Angle across the brick terrace toward the waypoint, jump down, and enter the drainage tile.

Take JAW rockets and two C4 charges from the cargo container near the tile.

Use the HMG or X-43 Mike to kill the three Ceph guards, one of which may be an Advanced Assault Unit.

Make your way atop the knoll and interact with the first vein. Pick up the HMG.

With “Flank” selected, return to the drain tile and go back. Move through the shallow ravine toward the waypoint.

Three Ceph, including an Advanced Ceph, guard the second vein. Take them out with the HMG or use a JAW rocket on the Advanced Unit.

Sabotage the second vein.

Head south through the ravine toward the third vein's updated location. Hide behind a metal barrier to observe the heavily guarded vein. A Devastator will be among the seven or eight defenders. Note the hillside position as your staging area.

Recharge and walk toward the underpass. Take the fresh HMG from the mount on the overlook. Ensure you have the X-43 Mike, Grendel, C4, JAW rockets, and grenades.

Move back to your staging point on the hillside overlooking the last vein.

Recharge, cloak, and slowly approach the last vein. If needed, JAW rockets are in the cargo container near the raised objective.

Use stealth to walk up to the raised platform, jump up, drop the HMG, and interact with the last vein. Pick up the HMG and jump off the rear of the platform.

Enter the tunnel-like passage behind the platform, located on the left side of the area. Move through it and go for the ammo cache. Keep the X-43 Mike and Grendel.

Advance into the crevasse toward the Litho-ship entry, guarded by four cloaked Ceph. If you don't have the “Cloak Tracker” upgrade, purchase it for 16,000 Nano Catalyst.

The cloaked Ceph are similar to Advanced Ceph Assault Units but with cloaking ability and are more durable. They attack with melee and ranged projectiles. Use the HMG, X-43 Mike, or Grendel. The K-Volt can make them visible briefly, but the “Cloak Tracker” upgrade and Nanovision are more effective.

Retreat near the ammo cache and attack with the HMG. Switch to the X-43 Mike if needed. Use JAW rockets, C4, and grenades.

Once the four cloaked Ceph are defeated, grab their Catalyst and enter the Litho-ship cloaked. An Advanced Assault Ceph or two may lurk near the entry.

Follow prompts to activate armor mode, crawl, move forward, and jump to complete the Chapter and the game. If the sequence fails, there's a checkpoint at the entrance.
