Entrenched
Modern Warfare 4 Walkthrough
The only full campaign mission you can walk through before October 16 is Entrenched. It is a linear assault: take the northern trench, relieve pinned friendlies, enter the power plant, shut reactor two, then flood coolant when the tanks rupture. This walkthrough matches what IGN and GameRiot recorded in the beta. The shorter procedure with the embedded video lives on how to complete Entrenched.
Difficulty names in the beta were the usual Call of Duty ladder. Regular is enough to learn the mission. If enemies keep spawning, you are holding a lane instead of pushing the objective — Entrenched uses old-school infinite spawn pressure until you move.
Trench line and the road to the plant
You start under fire with armor in support. Command will call close air on the northern trench; let the strike land, then push. Do not farm the first ditch. The mission wants you on the road toward the power plant with Lieutenant West’s element. When Echo platoon is pinned, that is your first “go fix it” beat — clear the BMP or technical that has them stuck, then rally.
Park is told to take the wheel in one of the mid-mission beats. Vehicle sections in this mission are short on purpose. Stay with the convoy silhouette, not a side alley. The plant skyline is the landmark: if you can see the cooling structures, you are on the correct axis of advance.
Power plant, control room, reactor 2
Once you are on the plant grounds, the objective flips from “take ground” to “shut it down.” Your squad is the closest unit to the control room. Fight to the interior, ignore optional side rooms unless you need plates or ammo, and enter the control space to begin the shutdown.
Reactor 2 is the first door on your right at the end of the walkway. That line is in the mission audio for a reason — players overshoot into security spawns. Open the door, drop into the reactor level, and listen for the coolant instruction. This is the same sequence shown in the IGN 17-minute capture used on the how-to page.
Coolant tanks and the yellow pipe
When the coolant tanks rupture, you cannot plug them the tidy way. You have to flood water directly into the reactor. Look for the yellow pipeline. It leads to the emergency valve. Open the valve to divert water into the core. If you are scanning grey industrial pipes, you are on the wrong color.
Stay on the valve until the objective ticks. Leaving early to gun a spawn wave is how people fail the beat. After the core is cooling, follow West’s extract call — the mission wants a push out, not a cleanup of every remaining soldier. For the video-led version of this same route, use how to complete Entrenched. Story context sits on story.

Frequently asked questions
How long is Entrenched?+
Most Regular runs land between 15 and 25 minutes depending on how long you fight spawn waves.
Why do enemies never stop spawning?+
The mission uses classic CoD objective pressure. Push the next yellow objective instead of holding a corner.
Where is the emergency valve?+
Follow the yellow pipeline from the ruptured coolant tanks. Grey pipes are decoys.
