Vaults | Museum Of Military Glory GoW: Judgment Guide

There is a declassified mission symbol on the right wall. After accepting it, the visibility gets reduced and when you get to the next room you'll be attacked by Therons with cleavers. Try to stay in the room with a declassified mission symbol and wait there for enemies. It is best to use against them any Shotgun or Grenade Launcher. Jump aside when you see them preparing to attack you. Prepare also to repeal several Boomers. After getting deeper inside the room, you'll be attacked by next wave. In the center part of the room, on the left, there is a Gatling gun next to the crate and further you'll find an ammo crate. Back off behind any cover and wait there for enemies.

There is another COG Tag on the right side of the room, between a large hole in the floor and the wall. Go up the stairs and turn into the right corridor to end the mission.
