Part 42

Launch the Dog (DB) through the XP (experience point) and follow it into room #1. Move right out of the guardians' Line of Sight (LOS).

Launch DB past room #1's EP (exit point), pull a Grenade (G) and move to its XP, crouch, and side-creep right through the XP for LOS on the crate at the far end of the hallway (Hlwy).

Toss the G 'AT' the base of the crate. ASAP, switch to the Pulse Rifle (PR) and begin firing on the group. If successful, all 3 will drop; if not, pick off survivors.

Switch to the Combine Barrier (CB) and scope it. Stand and remain on the left as you move toward room #2. A Barnacle (BG) will appear on the walkway (Wkwy) to your 1:00/2:00. CB it, then retreat to your previous Forward Position (FP).

Prep for Manhacks (MHs) while waiting. When you hear the gate to room #3 begin to open, switch to CB and move a bit into the Hlwy for cover (press the cover button to crouch behind walls or objects) from the crates area in room #2.

Warning: Resist the temptation to toss a G at the]$. Combine barrier (MGT) at the far end of room #2 while waiting for the BGs from room #3, as multiple MHs and the BGs will swarm your position, overwhelming you.

Scope the CB. 4 BGs will enter room #2 from room #3. You may be required to move back and forth through the XP to avoid extreme enemy fire.

When room #3's BGs have been cleared, stand and move toward room #2 while pulling a G. Toss a G toward both MGTs at the far end of room #2.

When clear, rush into room #2 past the Antlion (AL) spawning pit to activate it, then revert to your usual method for clearing room #3 and the upper floor.

Once the XP to room #2 is open, sprint to the side of it and toss a G at the MGT behind the table.

When the MGT is down, toss a G at the base of the fence blocking the duct. When the duct has been cleared, fetch DB and return.

Launch DB into the duct, then sprint to and enter the duct. Use the cinder block to jam the fan. Grab DB, move to the next duct entrance, and drop DB to the side.

If a BG is standing in front of the grate, punch the grate to eliminate the BG. If so, odds are high 2 remaining BGs will be in the next room waiting for you.

Back out and grab DB. Use DB on the BG that's always crouched against the opposite wall, then quickly pull DB back to you.

Exit the duct cautiously until you are sure of BG #3. Grab DB and shove it back into the fan room. Pull the plug, bust the SCs (Security Cameras), tip the MGTs, and head up the stairs.

Complete the room up the stairs with the 3]$. Combine barriers (LMs) in your preferred fashion. Ensure you also complete the EB (Explosive Barrel) and 2 MGTs before retrieving DB.

In the CR (Control Room), do not attempt to place DB in the MGT closet with or without the MGT; the outside lever is broken.

Keep DB away from combat areas unless you can eliminate enemies before they toss Gs or explode nearby EBs. Leave DB in the next CR before the Laundry, deep in the far corner.

Remove the 2 MGTs covering the Laundry EP, then head back to the CR to ensure DB is still inside.

Sprint back and pod the room; you won't get as many ALs to help with all the BGs, so you'll be doing some of the lifting.

When the room is cleared and the MGT is down, retrieve DB and release it in the middle of the Laundry.

There's a decent cache in the small Laundry room along with a PST (Pistol ammo), deal with it as usual to rebuild supplies.

When complete, leave DB and head up the stairs to the next area. There are at least 3 LMs spread out over the area, not to mention 7 MGTs and 8 OBGs (Outer Barnacle Grunts).

Once the areas are cleared of LMs, BGs, and MGTs, bring DB up into the final NP (New Project) CR.

Approach the hole from the left leading corner. Use the pit's 4x4 perimeter wall framing, hold DB directly overhead, and run forward along the wall's 4x4s, then right at the corner. You'll drop straight down after the right turn; keep DB overhead.

In the water, locate the light above the pit and orient it to your 9:00/11:00. FL (Flashlight) on, then position DB in front of you and slowly submerge.

As soon as DB slides under the tunnel ceiling, swim forward. Remain to the left side of the tunnel, turn left at the corner, and locate the barnacle tongue in the water.

Swim up the left side of it and jump onto the beam. Let the suit recharge, then drop into the next area and swim out to air.

Locate the chopper tram lever; jump onto it then to the tram. Walk, run, sprint, and/or BH (Boost Hop) along the top of the tram cable toward the sunny tunnel exit, bothered by zero Zombies (Zs).

Once outside, bear right along the trains. (With DB, use it on the speeder; no DB, use a barrel). Grab a barrel from the top or bottom and activate the train car speeder. Launch head-on as it hits the ground.

(With DB) GGP+ (Grapple Gun Plus) DB toward the end of the train car in the distance, then sprint toward the train car while the sniper deals with the Zs and DB. You may or may not take a hit by the time you reach cover beside the train car. DB will tend to follow you close enough to GGP-. BH along the train car.
