At the start of the mission grab the armor if you need it and the Grenade Launcher in the hallway in front of you. Make sure you take out the Spike Mine flying towards you and then enter into the first doorway on your left. This room is totally optional but you'll find Secret #1 and Secret #2 inside as well as a Double-barrelled Shotgun. In order to reach Secret #1 you'll have to perform a rocket jump which makes this one of the more difficult secrets to obtain.
Once you have collected both secrets you'll be teleported back to the start of the mission. This time run by the room on the left and go deeper; the very next room you come to will have a fork - one path goes left up some stairs and the other path goes to the right. I recommend you follow the right path first since it will lead you to Secret #3.
You can also grab the Pentagram of Protection in this area which you'll want to use to reach Secret #4 - which is found by following the left path at the fork. In the same area as Secret #4 you'll also find a Quad Damage power up, this is found above the secret on the catwalk. Sadly there isn't much to use the power up on since it's in a meh location.
Now that you've got the first four secrets done it's time to go back down the path that Secret #3 is located in. You'll want to continue down this hallway until you run into the locked Silver Key Door. To the left of this door in a small corner you'll find an elevator that will shoot you up to a small alcove with the Silver Key. Grab the key and open the door -- before you go any further make sure you take out the Spike Mine that is about to blow you up. This Spike Mine is the #1 killer for me on all playthroughs, I always forget it's here and it'll one shot you even with high health.
After going through the door you'll find the locked Gold Key Door to your left and to your right will be a room with some spike traps (pictured below).
These spike traps can be a pain to get through if it's your first time. My advice is to actually use a rocket jump to get over them; you don't need to jump over all the spikes although you easily can. Instead you'll want to aim for the boxes on the walls that the spikes come out of. If you can get ontop of these boxes you can safely run across the entire room and jump down on the other side.
In the next room you come across you will find Secret #5; after obtaining this secret you will want to step onto the skull picture in the corner of the room to teleport out. Across from Secret #5 you will find a table with a torch on either end of it, in the corner near this table is where you will find the skull picture to step on.
Stepping on the skull picture will send you to an area above the Silver Key Door, up here you will find the Gold Key. You'll also find Secret #6 by climbing along a narrow ledge above the Silver Key Door. Once you've obtained the Gold Key use it on the locked door nearby to find the final portion of the level.
Grab the Proximity Gun and coffins will slide out filled with zombies. Depending on your difficulty other enemies may spawn too (like a Fiend). You will need to defeat all enemies that spawn to advance, once you do it's one more hallway before the level's exit.
Secret #1
Secret #1: When you start the mission you'll want to enter the first door on your left, here you'll find a large room with some coffins and a giant shelf. There are two secrets for you to find in this room, the first one is found by rocket jumping onto the shelf shown in my pictures. You don't need to reach the top of the shelf, in my experience landing on the 2nd row is enough. When you land in the right spot you will open the nearby.. oven-looking thing. Grab the Horn of Conjuring as your reward.
Secret #2
Secret #2: The next secret is in the very same room as the previous, for this one you need to jump inside one of the coffins that has a skull symbol inside. This will lead you to a room with some ammo and Mjolnir.
Secret #3
Secret #3: Not too long after the room with Secret #1 and Secret #2 you'll find this one. To reach this secret you'll need to bounce up to the top area and run/jump across the beam to reach the other side. Inside this secret area you'll find some rocket ammo.
Secret #4
Secret #4: You'll find this secret in the room with the catwalk that goes over top of the lava. The best way to get this secret is by using the Pentagram of Protection that you get in the nearby area. It's typically best to grab that and run into the room with the catwalk, jump down into the lava and swim to the opening with the secret.
Secret #5
Secret #5: The next Secret is found in the workshop you come across with the headstones/face blocks piled up ontop of each other. Inside this room you will also find the teleporter that takes you to the Gold Key. To reach the secret you will need to climb ontop of the headstones/blocks and jump into the cavity that opens up.
Secret #6
Secret #6: Our final secret is found in the same area as the Gold Key and the Silver Key Door. Just above the Silver Key Door you may notice a portion of the wall that looks a bit different from the other spots, you can enter via this location and collect the goodies inside. This area will lead you to a suit of red armor that you were able to see earlier from the lava catwalk portion of the map.
