DOOM + DOOM II: Picture Guide – Doom II – All secrets

S1
Move along the only way you can and take the first door left side. There are 2 switches. Right one first, then left one, will open a wall in the corner for some armor and hp.

S2-5
In the brown room where the exit is, depending on how fast you were, you can either still see the open wall 2 imps came out of or not. If not fast enough, interacte with that part of the wall and get in there for secret 2.

Still in the brown room, right side where you entered is a switch. Press it, ride up, interacte with the wall in front of you, get in for another secret. Hit the switch in there. Dont ride down, instead run over the edge and try to land on that small platform. Backtrack to the small round room in the corner, there should now be a wall open with a rocket launcer inside.

Back to the brown room, in the far right corner, opposite side of exit door there is now an opening to get outside for a shotgun.

S1
Get to the red key card. Left side of it is a wall you can interacte with for a super armor.

S1
In the outside area, after you picked up the blue key card. Open the blue door on the left side and you will find a switch in there. Hit it to make a wall rise up. Use the wall to run over into the opening in the ground for some goodies.

S1
Directly in the starting area, where the room with the moving windows is. Check where the blue lamp is and interacte with the wall there. Get in for a secret and some goodies.

S2
Where the red key card is. When you are up there, drop down on the left side and take the teleporter.

S3
After taking the teleporter from S2, backtrack to the slime pool where the blue key card was. Notice the slightly different looking wall there. Run over there and interacte with that part to open the wall and get the last secret of this level.

S1
In the starting area, there are a lot of windows. On the left side, you can see a balkony through the windows. Get over there and in the room you enter, interacte with the wall on the opposite side of the green tourch. This wall will open as well as a part of the ground straight ahead of you. Be quick and get in there for a plasma rilfe.

S2
Drop down left side where the door is into that dark room. On the left side, open the door and follow all the way to the sphere. Interacte with the wall behind it for a secret.

S3
You are in front of the exit door. Use edge on the left side, strafe run into the opening on the left side for the last secret of this level. (Can also be done from the walkway that leads to exit door.)

S1
Directly at the start. On pillar forward from the blue lamp, left side. Interacte with it for a secret.

S2
You rode down the elevator into a huge room with a slime river and the blue key card left side up. On the left side of the elevator is an opening in the wall. Get in there for a secret and take the teleporter back.

S3
You opened the blue door, dropped down and opend another door leading you into this area. The secret is straight ahead of that first stair case where that electrical sign on the wall is. You need to take the stairs up to where the red keycard is. On your way there, strafe run/drop down into said opening. Interact with the electrical sign to open the wall and get your last secret of this level.

S1
After you killed everything and that weird looking cube in the middle is available. Dont press it, just step on the platform first and activate the secret. Not sure if it needs to be done on the “yellow-ish” side or if that does not matter.

You can grab the yellow skull first if you want.

S1
Open a door that leads to this narrow room with the chainsaw in it. Walk over it and kill the 2 enemies that spawn. Secret cant be missed, a wall opened further ahead of the chainsaw.

S2 & S3
Now open a door that lead to the room with all the xxx in there. On each side where the enemies were is a switch. Press left one, then right one. Get into this room, kill all the enemies and hit the switch at the end of the room behind the left pillar. Get back into room you came from, the wall where the rocket launcher was is now open. Get in for S2.

Stay inside and shoot that wall on the right side where the candle is to open the wall and grant you the BFG = S3.

S4 & S5
Back in the spawn room, open a door that leads to this room. Shoot the skull and take the teleporter for your next secret.

Crossing over the edge of that platform you are on, opens a door on the right side in the slime. Get down there for secret, take hazard suit, all the items and the teleporter back.

S6 & S7
After the teleporter you are now on the opposite side from the platform in the room with the pillar in the middle. That pillar has 2 skulls on it. Shooting each skull will reveal one secret each, check the walls for openings that are now there.

S1 – 3
After taking the first ride up and pressing a switch in this area. Dont follow where the door is, instead strafe run over to the left side in this big area with lots of enemies. The platform surrounding the building in the middle will lower again. Get on it, that is S1.

On the backside is a door, open it and get inside for S2. Inside, check the wall that has a light pattern on the ground. Interacte with it for S3 a BFG.

S4 & S5
From the platform that had the blue key card on it, run over to where the armor is and follow the way. You will come to 4 skulls in a row with a sphere at the end and a switch. Hit it and carefully walk towards/at the edge. This makes a platform rise, giving you access to the rocket launcher. Grabbing it is S4 and will open a lot of walls with enemies. Get in the open wall on the right side, which counts as S5.

S6
Head back to the blue skull and hit it. A wall will rise and you will have 3 skulls available on a stone in the middle. Hit the one on the back left side first. You come to a section with lots of rising stones. They will all also lower to the ground. Take those stones and stay on the ground to get to a lot of goodies and a teleporter.

S1 – 7
Stick to the left and get into the dark labyrinth like room. There are 7 secret hidden in this area – to be precise only 6 but wall from 6 will directly lead to 7. Most will be revealed after shooting walls/doors with UAC written on them. UAC needs to be written in capital letters, those are the ones in question. I show one closed one for this section, just look around for them but most likely you will open them by shooting the enemies in there. So when you killed everything, just check everywhere.

In the right corner you can see a switch, press it and a wall will rise

Leave this one for last so you can directly continue to S7 – The wall that follows after the switch again with UAC on it – shoot it, grab the ammo pack and interacte with wall in front.

S8 – 11:
From the fight, follow the stairs and open the door. Fight of all the enemies and take the door straight ahead of you first. When opening the door, inside the room 2 wall will rise with lots of enemies in them and the areas said wall reveal count as secret 8 & 9. You maybe have to reopen them by opening the door you came in through.

In that same area on the left and right side you can enter into other areas. Walking over that one stair, opens yet another wall in the room on the opposite side of the stair you used. So do that on both sides for secrets 10 & 11.

S12 – 15
Get back into the big room you came in from the fight. Now take the door on the right side from initial door you came in and take left as soon as you can. Open door and interacte with the wall with the opening above. It will lower and you can get up for S12. Now head over to the rocket launcher and grab all the stuff for S13.

Get back through the door and move ahead. Notice the 2 suspisious looking cracked walls. Interacte with both of them , start with the left one then right one for S14 & S15.

S16 – 18
Directly from S15, you now have the blue key card. Take the door in this room and stick to the left until you are in the area from S8-10. Take the entry on the other side and a right. Interacte with that symbol on the wall to rise a wall in the slime. Follow all the way for a nice goody – reaching the area, getting on the platform and picking up the item are S16-S18

S1
Get in where you can see the green torch. When reaching the top of the stairs, a platform will lower on the right side. Ride it up, and interacte with the wall on the left side where the torches and chaingun are. Drop down for a secret.

S2
Shortly after S1 when you got the blue keycard and move back over the bridge with the 2 green torches. Check right side in the slime pool for an opening. Get in for some rockets and S2. Take teleporter back.

S3
Directly after openening the red door you have some pillars in front of you blocking the way. Notice the broken wall on the left side. Move towards pillars to open them and then interacte with wall. Get in for S3.

S1
Follow the left side all the way around till you come to a small staircase. Take it, turn right and go through the door on the right side. You need to use that switch you can see from the entrance to get up to the chaingun and ammo which is S1. Take the stairs and strafe run over to the closest box.

S2
In the same room as S1, take the teleporter. Hit button and ride up. Picking up the sphere is S2.

I recommed to make a save before S3 since the spot where you get teleported is kind of inconsistent.

S3
You got the blue key card and opened the blue door. Inside that room is a teleporter. Left to the teleporter is an opening with a switch. Hit it and take teleporter. I am not sure on what it depends that you land on the plateu with the mancubus on it or not. When on there, drop down into the opening for S3.

S4
Look for this door and open it. Follow the lights on the ceiling to make a walkway appear. Get to switch, hit it and turn around. Hit that other switch and get out of the room. Opposite side, is now another very dark room open. Get in for S4.

S1 – 4
At the start turn left and stick to the left wall until you reach a stair case. Take it and get inside the room. In the left corner from where you entered is a switch. Use it and a part of the wall will rise up. Get out and grab the stuff for S1.

After entering the room again, turn right and interacte with the 4 UAC boxes. They will lower and reveal another switch. Hit it and some stairs will rise giving you access to a teleporter. Stairs are on the opposite side of the wall thats open. Take it. Teleporting alone seems to already trigger S2 but from up there you can strafe run into the area with the health sphere.

Get back into the same room and now drop down the hole in the ground. Ride the elevator up and interacte with the skull right in front of you. Pick up the shells for S3.

In the same room where S3 was, is a teleporter and left to it an opening in the ground. Drop down, open door, kill mancubus and take the blue key card. Dont take the 2 teleporters behind it, instead take the stairs in that room and the teleporter that is up there. When you are teleported, S4 will trigger.

S5
In that dark room that was S4, interacte with the “inner wall” and it will rise as well as open an “oustide wall” to get out of the room. You next target is the building straight ahead from that opening. Drop down and get inside, open the blue door and go through for some items and S5.

S6
You dropped down from S5 and take a left where you can see invisibilty in the dark further ahead. That building to your right has an interactable wall on the backside with some super armor as S6.

S7
Head back to the room from S3 and this time take the teleporter that is up there. You will be teleporter where the 4 revenants were. Walk around until you get to the blue door and open it. Get inside and you will notice a switch. Using it will lower the platform with the chainsaw on it which is S7. Take the teleporter to get to a roof top and red key card.

S8
Back to spawn. From there you can see a black building straight ahead. Head there and around the corner is a switch. Use it, ride up and get into the only door that you can open. Strafe run over there for automap and S8.

Since most players probably wanna take the secret exit, only 10/11 secrets are described.

S1
First for the switch. Look for a building surrounded by lava and get up there. From top you can strafe run over to a teleporter. Take it and straight ahead in another building is a skull/switch. Run over there and hit that skull.

Now for the secret itself. Get back to the elevator from spawn and get into the building in front of you. Take the elevator up and notice the teleporter. Get in, when teleported use teleporter you came out of to get back. This will take you to the red key card. From where you landed and can see the card, drop down where I made the arrow for S1.

S2
Get back in the room where you started for S1 and use teleporter again. This time follow the way and drop down left into an opening. In that room is a window below, getting through it raises a stone plateu you need to get to S2. Now track back using teleporter and drop down the same hole again. This time you will land higher up. Strafe run over to the chaingun for S2.

S3
Get out of the window from S2 and turn left. In front of you you should see some sort of elevator further ahead. Move over there hit skull and ride it up. Up there is an invisibilty and the wall left of it can be interacted with. Do that and drop down for S3.

S4
Take the only way you can to get out from S3. Drop down to the ground and take the same elevator again that got you up to S3. This time, take the teleporter in the corner. On your right from where you teleported, hit the skull and ride up. Take a left immediatly and get down there where the green torches and BFG are. Kill everything that spawns, Then interacte with the wall behind where the BFG was – yellow key card. Turn around, hit the skull, take the stairs and turn left. Get down until you can barely see the lava on the ground. Notice the hazard suit. Strafe run over there, grab suit
and hit that switch. Now drop down into the lava and look for an opening in the wall. Get in there for an invincibility and S4. Move back to where you came from and check right side for a teleporter that will take you back to where yellow key card was.

S5 – Secret Exit
From where the yellow card was, take the stairs again and strafe run down to the door slightly right side. Take the door and notice the open wall on the right side in the lava with a hazard suit. Grab it and follow the lava into the opening on the other side. First left you can take is S5 and also secret exit. Just get in there but dont use the teleporter yet.

S6
From S5, follow the intended way till end. Hit skull and get back into room where suit was. Stairs are now available in that room. Take them up till skull, hit and ride up. You can now go left or right, take the left to find yet another skull. Timed stuff, so be quick! Hit this one, be quick and drop down into room where suit was again. Exactly where the suit was, an elevator lowered, take it and when up there grab the goodies for S6.

S7-10
Ride down from S6 and take the stairs again. Instead of left, go right this time and hit the skull. Get back down and interacte with this wall for blue card.

Get outside, over to that chage like thing, open yellow pillars, move ahead and open the blue door. Move along the only way you can. When the first wall moves, this also opens 2 small rooms. One left around the corner twice (sphere), for the other drop down on the stairs you used and you cant miss it (ammo). Be quick both are timed S7&8. Get sphere first, then into the other room.

In that room is also a blue skull, hit it and a teleporter will appear. Use it to get S9 & 10.

Head back to secret exit and take it.

S1
From the start take a left and the middle door. Thorugh the next door and you are into a huge room with flags. Take the right door, then right again and follow to the end where another door is. Take it and notice this totem in the room. Interacte with the wall behind it for S1 – BFG & lots of ammo.

S2 – 4
From S1 get back into the huge room with the flags, now take the door in the middle. Pass through the next room and in the following room take a left. Follow the only way you can and you come into a bigger room with green torches. Follow again the only way you can straight through 2 doors. Then left and trough the door you see the exit door ahead. Directly after entering, right side interacte with the wall for S2. In the secret is another wall to interacte with (S3) and in the next room another one for S4. Take the secret exit in S4 for another secret level.

S1 – 6
In the first room with the blue and green torches. The stones next to every blue torch can be interacted with to rise them up and give you some goodies. Those make S1-4.

On each side in the same room you have some flags on the walls. Interacte with the middle one on each side for S5 & S6.

S1&2
Get outside from where you spawn and stick to the left. Move along till you come to the backside of the “library”. Get in there and interacte with the torch on the left wall and the wall in front will be split leaving only the lower part of it. Now you to interacte with both “lower wall” in that room. They will lower and rise again, making it possible to first shoot the “eyes” in the wall and second shoot the “lamp” in the bookshelf. Doing so reveals both secrets. Make sure you really drop into the ground where the sphere is or otherwise the secret might not trigger.

S3&4
Now head back out the same way you got in and go straight. Take a left and move over to that “black/red” brick building. Open the door on the backside and get in. Reaching the area behind the door is S3. Interacte with the wall on the right. That lowers it, get on and ride up. Move over on the stone ledge and drop down. Activate the switch and get in for S4.

S1
After grabbing the red card and going in red door you hit a switch. Get to the other side and hit skull. You will ride down into another room with a skull. Hit that one too and ride up. Now in a room with a switch on the left and a skull right side behind the corner. Hit switch, then skull and drop down. Take the right at the acid pool and another right in that room. Drop down into the acid, there is a switch there lowering a huge part of the room and revealing another small room with armor in it. Get in there and when you take the elevator that counts as S1.

Getting Blue card & Red skull & S2
Move back to where you got to S1 and interacte with the wall on the left where the torch is. It will lower the wall in the middle between the blue torches. Get in and hit the skull in there. That will make a platform rise. Get over and drop down where you can. Another skull to hit that will make platforms rise. Get over where the suit and blue card is. Grab suit and blue card and move over to the blue door.

Finish that room to get the red skull – left side first, press skull. Then right side and follow till you can drop down and get access to red skull. Move along and open red pillars.

Move forward the only way you can, at a certain point you are here. When you press the skull and elevator will come down. On the right side wall where the elevator moves up and down is an opening. Get in there for S2. From S2 strafe run over/down and back to orange skull entrance.

S3
When you come to this spot, drop down on the ledge, interacte with stone wall to lower it. Hit skull and ride up again. Check right side, there is now an opening you can get in for some goodies and S3.

S1
In the huge arena, left side where most of the enemies came out of. Get in and follow all the way to find a BFG = S1. Hit switch to get back out.

S2
Move all the way over to the other side where you can see that invulnerability. On a wall there is a switch that will make a teleporter available. Get out quickly and turn right. Use teleporter to get to S2. use the 2 skulls to get back down.

S3
Just dropped down from S2, get over to those wooden crates. In the left corner is the yellow skull, in the right corner you have a suspicious shadow triangle on the ground. Move over there and get teleported. When you are out that counts as S3.

S4
Directly from S3, drop down and move right side into the corner for a teleporter. Take it, hit switch, then skull and you come into this area. Interacte with the green wall here and get through leading to a small labyrinth area. Straight ahead, then left is a blue-ish wall. Hit that skul there for S4.

S1
After opening the firsts doors your are here. Take a left and press the switch in that room, then take the door that opened. In there open another door then press the skull on the left side to reveal a teleporter. Take it and the next room take the right stairs. Drop down and head straight till you see another skull in front of you. Turn right there and open the door on the right side for S1.

S2 – 4
Head back but instead of going outside interacte with the wall on the left side. Get in = S2

Interacte with the wall on the back. Get in and ride up = S3.

Ride back down and get back towards S1 this time take a left and through the door. Make a save here just in case. Grabbing the item will teleport you to here. Timed stuff following so be quick!
From the platform you land on, there are imps left and right side = closest to the door. Killing the ones on the right side does nothing. Killing one on the left side will make a platform rise giving you access to the door – be quick and strafe run over there while it is moving up. (Also 4 enemies down there. Would suggest you leave them be because killing them takes to much time and you will miss the platform. If that happens you have no way of getting back.) Move through the door and you will see red skull ahead. Move there and pick it up. As soon as you enter the area where skull is, S4 will trigger.

S5
From S4, drop down and take door on the left side. When you enter, press skull on left side and again get in. Hit switch to raise stairs. When at the top turn left and interacte with the wall there. It opens, get in and up the stairs. When there, there is a red button. Hit it 4 times to make a bigger stone platform rise in front of you. Strafe run over there and from there onto the other one with the backpack. Take the teleporter there for S5. Interacte with wall in front to get out. It will bring you back to the area of S1. Dont go outside, open wall again and get up. From up there strafe run over into the water.

S6 & S7
Now here, just reaching the area is S6. Get inside on the left, find the skull and hit it. Lots of enemies will appear outside. Kill them all then check left corner for an automap = S7.

S8 & S9
From S7, now take the right into the building. Pass the crusher, kill all the enemies and take the stairs to find a switch. Hit it, kill all the enemies that spawn and take path into the huge room with 5 teleporters. Take the fruthest one right side first. As soon as you arrive = S8.

Grab blue skull and now head back to the 2 blue skulls from S1. This time hit the right one and quickly get back to room with switch. There is now a wall open. Follow the stairs, another wall will rise and entering grants S9. Grab yellow key.

S1
Turn around and drop down. While flying, the platform should already rise. Get on the backside and you can drop down there for a hazard suit in one opening. Run around and take the elevator that is in the other opening. Now you are back up.

S2
Black = normal way. White = little shortcut. I describe white.
Drop down again and take the right corner from the building run ahead and when you can run into an opening. Follow all the way till you come to this spot. Interacte with the wall on the left close to item and get in for S2. Take the teleporter in there, you arrive at a platform high above the ground. From there strafe run to the “ground”. (In case you fall down during fighting: On the ground you will see an opening. Get in and hit switch, take suit. Platform will rise again and you can take it up again to make
the strafe run)

S3
On the ground you will find a teleporter, take it. Take the stairs down and walk into the dark room. In there a wall will rise, revealing a minigunner & teleporter. Facing the teleporter, turn around and walk into the very dark corner. The wall is open there and another teleporter is in there. Take that one to S3.

S4 – S6
From S3 drop down to the ground and jump into the lava. Run along towards left side, you will find an opening. Follow the only way you can, ride an elevator and you are here. Press skull but dont move over the teleporter. Instead, start right from it and interacte with the wall. Get in, interacte with wall again to get to item. And then interacte again to get out again. Doing all of that counts for 3 secret, S4-6. Now hit the skull again and take teleporter to get back.

S7
Now here, take teleporter again to stairs with dark room from S3. This time take the “none” secret teleporter and you will come here. Let the platform lower itself and then run straight ahead. There is an opening down there, get in and follow the way. In the room with the stairs, right side of the stairs, interacte with the wall where the electrical sign is, for the last secret of this level.

S1
Turn left directly where you spawn and interacte with the wall there for S1 and some goodies.

S2
Still a spawn, interacte with the green torch and get inside on the right side where there is an opening now. Getting in there counts as S2. Take teleporter.

S3
When you arrive from the teleporter, you are on a platform surrounded by acid. Notice 4 different looking “animal/demon heads” on stones. Start with the “lion” on the left and follow all the way to another teleporter that will take you to the blue skull. Back on platform now interacte with the “demon head” on the right side. This will lead you to the red skull. When at the red skull interacte with the demon head on the wall there. Take teleporter back to S2 = counts as S3.

S1
When you blew up all the barrels, take teleporter and next teleporter. Then you are here where you have to press a switch to raise a platform to be able to get to the other side. When on the ohter side, stay on the top stair and take that opening there. Dont drop down on the ground, instead on this stone thing a little to your right. Turn around and get in for S1.

S2
Now drop down on the ground and notice a teleporter on the right side where the huge opening in the wall is. Run onto that teleporter. Now take the left opening and follow around till you come to the back with an open “room”. There is a skull on the wall, interacte with it for S2.

S1
From the start, take a right into the “red area” of the map. You come to here, move over there and grab the gun. Behind you wall will rise and an enemy appears. Kill it and get in there for S1.

S2 & S3
From S1, drop down into the slime and take the teleporter to your left. Move down those red pilars all the way, hit 3 switches and take 2 teleporters to come back to the top of said red pillars. This time, dont go all the way down, instead run over to the building on your left. Get in and doing so counts as S2.

In that same room is a computer console. Interacte with it to lower an elevator on the opposite side of the console. Take it up and grab the items for S3.

S4
Head back to where S1 was and move through the door there. Then drop down into the slime and turn left the first chance you get. Follows that way to 2 suits. Garb one and stick to the left till you come to a teleporter close to some metal structure next to it. Take it and from where you land, strafe run straight ahead to the invulnerability.

S1
After getting the blue skull, you are in this huge area with some enemies. After killing all of them, take the door. In the following corridor, check left side here and interacte with the wall. Get in for S1.

S2
After opening the blue door you are in huge room and have to take the elevator straight ahead. When up there, check left side wall and interacte with it here. Get in for S2.

S1 & S2
At the spawn, interacte with the wall right side from where you spawned. Get in for S1. Clear room and you will be back at spawn.

Now hit the switch, platform lowers and quickly interacte with wall that has the panels on it. Get in for S2.

S3 & S4
After opening the red door you have the blue card straight ahead. Grab it and interacte with the wall behind it. Get in for S3 and hit the switch in there. This lowers 2 platforms in the room before, left and right side. Need to be quick, the rise up again but can be lowered again by hitting switch. Get on the one right side first, press the skull. Back to switch, hit it and now left side. Getting up and grabbing item is S3. Check wall here you can interacte with for S4.

S1 – Timed, got 30 sec (Maybe make a save)
From the start use the stairs and strafe run over to where the door is. Open it and take a left, cant miss the items. After the mentioned time has passed, wall will rise again and you have no way to get it.

S2
Head back to spawn (slime pool with switch on structure or strafe run )and take the door to your right from where you spawned. Enter a library like room to your right. In there a little before the armor on the right side is a skull – press it. Get in, grab yellow skull and now there are 2 skulls you can press. Do that and an elevator will lower with some stuff on it. Grab items for S2.

S3 & S4
Get out of library and turn right. Walk towards the wall in front with the lamp on it. It will open and reveal some enemies. Kill them and get in there to get S3.

Get close to the crystal there to lower the wall (if that did not already happen), get over and back to where that hovering eye is. As soon as you are close enough, the wall behind it will rise. Again some enemies, again get in there for S4.

S5 & S6 (S6 still bugged, need no clip to trigger it)
Now head to the room from S1 again, take right and open the door. Get in the room and press the right of the 2 skulls on the blue walls. A part of the floor will lower, get in for S5. If you want, but the secret does not give you anything, activate “noclip” and get “on the teleporter” – counts as S6. Turn off noclip and continue.

S7 & S8
Get out of the room from S6 again and press the switch. Ground will lower, get in and through the yellow door. In the next room there is a skull on the right side wall. Press it to reveal some enemies. Kill them and get over where they were and grab the items for S7.

Now move on the platform/teleporter in the middle, enemies will spawn. Kill them and again move over to where they were and grab some more items for S8.

S1 -3
From spawn take the right side until you are in a bigger room with lots of enemies. After you killed everybody, check the opening on the left where the candle is and interacte with the wall.

Head back the only way you can and take the other way.

S4 & S5
Now in this area, follow where I made the arrow and simply walk through the stone wall on the right. You come into this area. Shoot the symbols to lower 2 walls. Take the left opening into the corridor with the moving spine wall. About half way in on the left side again you can walkt through the wall = S4. Then before taking the left, again walk through the wall near the right corner for S5. Grab the yellow skull at the end of corridor and head back into huge area.

S6 & S7
Look for the yellow door but instead of going through it take the stairs into another room with 4 moving face pillars. There is throne in there, get on it to lower the platform in the middle of the room. Get on the lowered platform for S6.

Stay on it and let it rise up. Notice left and right side, one skull each with red eyes. Interacte with the one on the right side (facing items in front of you) to spawn enemies and also open a wall behind the throne. Get that invulnerability there & also a teleporter is there. Stepping on it is last secret of the game S7 and again spawns some enemies.
