Main Entrance | The Courthouse GoW: Judgment Guide

Go inside the room. There is a declassified mission symbol on the left wall. When you activate it, you'll be limited to boomshields and Sawed-off shotguns only. Knock through the door - on the left side you'll find ammo crate but save it for later. After entering the main hall you'll be attacked. Retreat to the passage with ammo crate and stand behind the boomshield, thus blocking the passage. Wait here for Wretches and Bloodmounts. Try to shoot monsters first and after that - their riders.

When the situation calms down, you can go to the next room and shoot backs of entering enemies (opponents with flame throwers among others). After killing the last enemy, go down the stairs to the bottom of the hall. Enter the room on the right to find a COG tag on the ground.
