E2M4 - The Ebon Fortress

Secret 1

From the start of the level fall down the ledge and then enter the water. You will turn right and then enter into some shallower water.

You will see this.

Although it doesn't appear to be present here you will see a lighter area where the red lines indicate. What you do is walk to the wall and let yourself sink. Then you will enter an airless cavern, with a quad. Take it and then exit before you start to drown.

Secret 2

From the picture, above, you will notice a platform in the top left hand corner. You will need to find your way there, as it is quite a lengthy path to follow. However when you come from the inside to the outside, you will probably be there.

You will need to go down the stairs on the other side, go forward a bit and you will see this.

The secret door is a different colour and you will need to shoot it for the door to open it.

Secret 3

When you exit from the room in #2 you will see stairs directly in front of you. Follow the stairs until you see something like this.

Shoot the door first then make the journey. You will fall into a room, below, if you miss-jump the ledge. You will find 100 health inside.

Secret 4

As you follow the stairs, seen in the above picture, you will come to a vestibule on your left, here you will get to a path which is above a long river of slime. Follow this around until you come to a normal doorway, to your left. If you see Stained Glass windows you have gone too far.

You should see this:

Make it fast, as the slime will take your health. There will be red armour and an environmental suit, to get back in.

There are no more secrets this level.
