► How do I avoid the Decontamination Gas?
You can avoid the gas by standing outside of the facility or wearing a full Gas Hazmat Suit.
► How do I give scanners a security level?
You just have to place a Keycard scanner and right click it with a keycard that has the level you want the scanner to detect.
For example: You want a Keycard scanner with security level 3, you have to click the scanner with a Keycard with the level 3. Keycards with higher security level can also access the scanner after setting the security level to 3.
Same goes for Hand Scanners. Just right click it with an empty hand and the Hand Scanner will set the ID to your playername. Only you can activate this Scanner now.
► How do I disable the Lockdown, Decontamination or else?
You can disable a lockdown or decontamination by entering C.A.S.S.I.E. Menu and click on Lockdown or Decontamination.
► What can I do with C.A.S.S.I.E?
C.A.S.S.I.E. is an important block you need. When you have C.A.S.S.I.E. you will get notified about events with messages.
You can also right click C.A.S.S.I.E. to turn it on and enter the menu, but first you have to login with a code. After that, you can choose 6 options.
- Lockdown = Closes all doors, gates and disables foundation buttons, tesla gates, keycard scanners, computers, alpha warhead panels.
- Decontamination = An event where the facility will be locked down after a while and start releasing toxic gas that kills everything inside.
- Doors = Can open or close all doors and gates at once.
- Tesla Gate = Can activate or deactivate all tesla gates
- Restart = Only necessary if C.A.S.S.I.E. got hacked.
- Shut down = Shuts down C.A.S.S.I.E.
If there is a green marker next to the option, this will mean that the following option is already engaged, tesla gates are active or doors and gates are closed.
To disable Lockdown, Decontamination, Tesla Gates or opening/closing all doors, you need to click the option again.
If the text is in a dark gray, that means the following option can't be clicked, due to other actions like a Lockdown, Hack or Decontamination.
► Which events are present in the mod?
There are 4 types of events that can happen:
Lockdown. This event will close all doors and gates and cannot be opened. Foundation buttons, tesla gates, scanners, computers or alpha warhead panels won't work either. This event is often the result of other events or by C.A.S.S.I.E. You can disable this event with C.A.S.S.I.E. During this event, you can hear Ambient Noises.
Facility overall Decontamination: This event will release toxic gas into the facility. This event can be triggered or disabled with C.A.S.S.I.E.
Alpha Warhead Emergency Detonation Sequence: This event will explode the Alpha Warheads which results in a HUGE crater. Be careful with this event. It can be triggered or deactivated by using the Alpha Warhead Panel. Deactivation only works before the Lockdown takes place.
C.A.S.S.I.E. Hack: This event will take place when the Chaos Insurgency spawns and trys to walk to C.A.S.S.I.E. within a 50 block radius. If they reach C.A.S.S.I.E. they will hack into C.A.S.S.I.E. and start the Facility overall decontamination event, and also a lockdown in each zone. To stop this event, you first have to kill the Chaos Insurgency members, restarting C.A.S.S.I.E. within the C.A.S.S.I.E. menu and also disable the decontamination and lockdown.
Containment Breach: This event will only be triggered if a player enables it in C.A.S.S.I.E. During this event, the monitors will show an Emergency screen, C.A.S.S.I.E. shows red screens and you can sometimes hear ambient noises. During this Event, NTF Units can spawn, perfect for roleplay.
► Does the Tesla Gate kills SCP-106 instantly?
Yes, the tesla gate is compatible with the SCP-106 Mod and kills SCP-106 instantly
► Does this mod include SCPs?
No, the SCPs themself are seperated mods. This mod only adds building blocks, decorative stuff, labels and more but not the SCPs themself.
► Does the mod work with other SCP Mods?
Yes the mod works with other SCP mods aslong as they are both from the same creator named Zcoper. SCP mods that aren't from the same creator won't interact with this Mod.
► Why do some blocks don't change their texture?
Some blocks of this mod can change their texture during events. But this only works 10 blocks under or above the block limit (world height)
► What are the login codes?
You have to enter a code to login to certain systems. You do not have to enter the login code if you use a keycard with the security level of the O5. The code is entered in the order of the numbers
Computer Code:
9 | 4 | 10 | 5 | 1
2 | 6 | 8 | 3 | 7
Alpha Warhead Code:
2 | 7 | 3 | 5 | 9
4 | 1 | 10 | 8 | 6
C.A.S.S.I.E. Code:
5 | 2 | 8 | 4 | 9
7 | 10 | 6 | 1 | 3
Verification Code:
1 | 2 | 3 | 4 | 5
► How do I open Doors and Gates?
You need to open the doors and gates with a foundation button or a scanner near the door/gate.
This only works if there is an active Generator in the world.
► Why can't I use some blocks?
To use the certain blocks and systems, you need a generator that is active in your world.
► Why do events continue even when I stopped them?
This can happen when you activated an event, stopped it and started it again within 2 - 5 minutes. But only if it's the same event. Just wait a bit before starting the event again.
► Why does the system shut down if I disable an generator but have multiple ones, same goes for C.A.S.S.I.E.
You should only have 1 generator or 1 C.A.S.S.I.E. in your world. If they get shut down or else, a variable is change which applies for the whole world.

The mod includes a large collection of SCP Foundation styled building blocks and decorative elements designed to create detailed facilities. Players can build everything from containment chambers to hallways and control rooms using new blocks for walls, floors, ceilings, glass, fences, grates or even new light blocks. Some blocks define facility zones such as Entrance Zone, Light Containment Zone or Heavy Containment Zone, allowing doors and gates to function correctly during events, if they are placed on a specific block. In addition to building blocks, the mod provides decorative elements like pipes, vents, fans, tables, chairs, metal ladders, caution tape or wet floor signs. Tesla Gates are also added which will shock anything going through it. New Foundation Doors or Gates are a must have in Facilities. Storage blocks like shelves and drawers allow basic item storage, making facilities feel more functional and alive. The Mod not only introduces blocks, but also items like keycards, medkits, the S-Nav to detect SCPs, Armor and two new weapons. There is so much you can do with these new additions!
