The title of this level is apropos: you’re going to face ogres, ogres, and more ogres. You’ll be so used to the sound of buzzing chain saws and falling grenades that it probably won’t even faze you by the end. While the castle itself seems huge - with several floors and a large moat to explore - you’ll really only need to enter a few rooms. Players interested in simply finishing the level should just head into the castle and make a bee-line for the gold key, your ticket outta there. Those looking to find all the goodies, however, will have to do a little exploring.

Beyond this zombie lies the first Secret Area of the Ogre Citadel

To extend the bridge leading to the castle, shoot the two red buttons on either side. Opening the castle doors releases a fiend, who will immediately come a-running. If you shoot the buttons quickly, the bridge won’t extend in time for the fiend to make the jump, and he’ll fall in the moat. This will make it easier to dispense of him and his buddy down below once the rest of the monsters in the area have been dealt with.

Secret Area 1
Drop into the moat before entering the castle. Find the cave and walk to the back wall, where you will find an elevator and 100 health kit.

Secret Area 2
From the elevator in Secret Area 1, head left. Continue around the perimeter of the castle and under the yellow armor on the bridge. Find the dark room where the moat ends and turn around. You’ll see some steps and, at the top, a grenade launcher. Take the grenade launcher.

This Quad Damage will come in handy against the army of enemies waiting below

Do not enter the door that opens when you nab the launcher. It leads to one of the most dangerous sections of the castle, and there is a much easier way to tackle this region. Instead, head back around the moat until you find an arrow pointing up. There is an elevator here, which will take you right to the castle entrance.

In the entry hall, take a right toward the gold doors to avoid the hallway of ogres. Follow the stairs up and around, then head across the overhang, where you'll find a Quad Damage. From here you can drop down into the hallway with a much better chance of taking out the ogres and the shambler waiting below.

Jump out this window to the small ledge below. You'll see a bridge leading over the moat to the room across the way

The Gold Key - From the platform with the Quad Damage, you’ll see another elevated platform directly ahead. On the back wall of this area is a star button, which will open the passageway containing the gold key, which can be found in the shambler’s lair at the end of the hallway below.

Secret Area 3
After defeating the monsters in the central hallway, go to the window, where you will see some ogres in a room across the way. Jump out the window and land on the small ledge just outside. Follow the path to a bridge across the moat and into this room. This will take you to a yellow armor, a 100 health kit, and a teleporter.
