Dash trough it and take a left and run some more to safe ground where you find secret number 2.  But the way back will be as painful as the way there.
3.  One of the most painful secrets.  Well, at the end you have to cross this toxic waste puddle (quite deep).  Instead, dive down and discover secret number 3.
4.  This one is found at the blue door.  Shoot the dig piece of wall that has the symbol on it.  It will open and you can enter, but:

In the.BSP file: "message" "You have found a secret." "origin" "-1640 -1300 156" "spawnflags" "2048" "targetname" "t117" "classname" "target_secret"

If you go to the blue door and shoot the wall to the right of it, and jump in there and then do a "viewpos", you'll see that you're standing right on top of the secret.  But you don't get credit for it because there's no trigger for target t117 anywhere in the.bsp file.  I don't know much about quake editing but I think that's what's going on.  So there wont be a message for you finding this last secret.  But this is where it is.

Lower Palace (6 secrets)
1.  If you are coming from the sewer entrance from OUTER COURTS you will come to a room with some tanks.  Shoot them and their explosion will open up a secret corridor.

3.  When you are going up with the high elevator to one of the UPPER PALACE entrances you can see a large display with yellow and red colors.  Shoot it and a secret passage will open.
4.  Remember that pillar of water or blue light or whatever it's called.  Anyways, there is a quad on top of it.  In order to get it down, you have to shoot the faces on the two walls in front and behind it.  The pillar will come down and you can collect the quad.
5.  You will find it at the second entrance to UPPER PALACE.  Inside a room you will find a panel.  Try pushing the wall beside the panel and then the secret will open.
6.  Go to the balcony (big low one) looking down at the cd-writer for the comm laser.  If you are facing the computer, take a left and there should be stairs leading down and a quack right leading to a door.

Upper Palace (7 secrets)

Then try shooting at one of the corners up there.  The wall will open and you have found your first secret.
2.  If you instead of going up like in secret number 1, go down to the lowest part, you can shoot a hole and find secret number 2.
3.  When you first encounter the four blasters popping up out of the wall, I recommend to dive over the edge at the upper right corner so you won't land in any of the lava.
4. when you first enter from the lower palace (this is the entrance that brings you to the semi-spiral staircase up to a corridor with a railing and an elevator gong down.  Down below there are a couple grunts, and a yellow forcefield.  To the left of the forcefield, and up on the ceiling there is a secret, if you stand under it long enough a monster comes out of the ceiling (on of those cylinder flying things) then after you kill him there is a shootable button, shoot it and a enviro suit falls out.
5.  Nearby the two periodical flames there is this hole hidden in the darkness in a dark corner.  Just walk into the dark corner and you will automatically fall down into secret number 5.
6.  At one of the starting positions when you arrive from LOWER PALACE you start the level looking at two doorways blocked by forcefields.  Open the forcefield on the right and step through the doorway.  Shoot the ceiling and a secret will open in front of you.
7.  Ok to get to the easter egg, after doing secret number 2 where you shoot the wall there is a puddle of green slime in the floor.  In the corner there is a small stone sticking out of the wall that you need to press up against and it will open the wall that's under the slime.  Now you can swim through the slime, ick, to a hidden room.  The room is full of things from id software's past that they try to seal away behind the wall.  Don't forget you need the red keycard (in the outer courts) to drain the fluids in the tank to expose J. Carmack's head (?).  Also don't lose your head (take it with you).  There is a much smoother way back.  Shoot at the wall opposite to the head tank and go through secret 2.
