The Nameless City

The penultimate level is a maze of corridors. Just finding your way around can be difficult enough, let alone finding all of the goodies. Luckily, most of the secrets are located in one central area. Once again: save ’em for when you really need’em.

Secret Area 1
Most of the secret areas are located in the central area with blue-bricked walls. When you come across a biosuit, grab it, turn around until you see the red armor, and run up the steps. Make two quick lefts until you see a Quad Damage. As you approach the Quad, the floor will open, dropping you into some toxic slime below. Grab the Quad. Do not enter the teleportation portal. Instead, go around the corner where you will see another portal, leading to the area with the red armor.

Don't enter this teleporter, no matter how tempting it may be. Instead, continue though the slime around the corner to another teleporter leading to a red armor and lots of ammo

Shooting this red button will cause the steps to rise, granting you access to a previously unreachable area

Secret Area 2
Find the elevated platform with a Ring of Shadows. Nearby, you will find a "T" intersection with a dead end on one side and two small sets of stairs facing each other. Behind one of the steps, you can see a red button. Stand on the bottom step and shoot the button, which will cause the stairs to rise, creating a new staircase to a secret level. Jump up the new steps to find some ammo, health, and the Ring of Shadows.

Secret Area 3
In Secret Area 2, notice the small opening on the wall to the right of the torch. Shoot the section of wall just below it to open an area with a vore and a Quad Damage.

When you reach the Ring of Shadows, shoot the wall on the far right to access a secret room and this angry vore

Near the Ring of Shadows, you'll see this dark hallway with two small circles of light on the walls. Each of these lit areas leads to a secret alcove containing a box of rockets

>Secret Areas 4 & 5-
While still in Secret Area 2, look at the two light spots on the central walls. Hit each of these walls to reveal a box of rockets. Each counts as a distinct secret area.

Secret Area 6
In the room with the steps leading up over the pool, jump into the water and turn around. Swim under the bridge and press the wooden Quake symbol. You will get the message "A Secret Lurks in the Hall at Red Brick." Turn around and go through the teleporter (leave the Quad Damage for later). You will appear on the steps. Turn around and head back to the red-bricked area, where you found the biosuit. A large area will have opened, unleashing some monsters. Go up the steps to find some rockets and some cells.

Shoot the red area of the ceiling to extend the platform across the water below

Each of these alcoves, which previously contained vores, holds helpful powerups. They also mark the locations of the two secret areas in the water below

Return to the steps over the pool. Look up and shoot the red window on the ceiling. A platform will extend, allowing you to jump over the pool. Drop into the water and grab the Quad Damage. Go through the teleporter and jump over the pool. Now you’ll have an advantage when you face the vores in the silver key room.

Secret Areas 7, 8 & 9
In the Silver Key room, grab the power-ups and defeat the shambler. Jump into the water, where there are two secret areas. One, containing two boxes of rockets, is located under the Pentagram alcove. The other, containing a teleporter, is located under the Quad Damage alcove. It will take you to a 100 health kit right above Secret Areas 3 through 6. When you grab the health kit, it will register as another secret area.
