Great Staircase is the sixth chapter of the sixth act in Gears of War: Judgment.
After exiting the courthouse and walking past some rubble, you will find yourself near a small ammo supply. All you need to do is find the King Raven and board it. There'll be many weapons including Lancers, Shotguns, Grenades and a Tripwire Crossbow, amongst others. You'll also find the Declassified Mission below the statue.
"Col. Loomis's report stated clearly that all COG ammunition was stored safely and securely."
This mission will give you 5:20 minutes to complete the chapter before the ammunition blows up and kills you. Move fast, kill your enemies as fast as you can, and avoid damage as much as possible.
Afterwards, an E-Hole will spawn. Close it and take down the nearby Locust. This time, almost all Boomer and Drone variants will attack so watch your back and don't be fooled by their strategies. After closing the first hole, the ground will shake and a Boomer will appear in front of you and then suddenly Col. Loomis will come out of a door and shoot it dead. Cole will ask where he was, to which he responds he was killing all the grubs you left behind.
More Locust will appear and elites will start to show up. Use any weapons at your disposal to kill them. Fight your way through the staircase until you find the Raven. Once all enemies are down, head towards it and the chapter will end.
Near the end of the chapter, find the Crimson Omen and walk upstairs until you reach a COG Tag at the end of the path.
