SCP Additions is an SCP survival horror and facility-building mod for Minecraft. Inspired by SCP: Containment Breach and SCP Unity, it combines functional SCPs and containment machinery with a custom inventory, survival systems, keycard security, animated doors, and a large collection of facility-building content.

Gameplay Features

Inventory

SCP Additions includes a complete Survival Horror inventory interface inspired by SCP Unity with multiple specialized storage categories.

Items can be moved, equipped, used, dropped, or stored through a custom interface designed around limited resources and deliberate preparation. Vanilla and modded items are automatically recognized whenever possible, making the system work naturally across larger modpacks.

Status

The Status panel gathers your condition, including active effects, health, armor, stamina, combat attributes, and blood type.

Crafting

In the Crafting tab you can craft items in a 3x3 grid. Crafted items will be remembered as Recipes and you may pin important ones to be more easily used again.

Codex

The Codex turns documents into collectible records with custom text and images. It can be used for SCP files, personnel reports, photographs, maps, story entries, or any other document needed by a custom facility or adventure map.

Contextual Interactions

SCP Additions includes a contextual interaction system for blocks and entities.

Configured objects can display SCP Unity-styled prompts, icons, and other conditions.

Dropped items display a pickup prompt by default.

Health, Stamina, and Horror Movement

Custom health and stamina displays replace the usual HUD with a presentation inspired by SCP Unity.

Walking is slower, sprinting is more committed, and stamina becomes an important resource while escaping threats or crossing dangerous areas.

Blink and Eye Effects

Players need to blink when near SCP-173.

In-Game Configuration Center

The major systems of SCP Additions can be customized through a dedicated SCP Unity-inspired interface inside the game. It includes editors for gameplay modules, inventory behavior, Codex documents, interactions, SCP-294 drinks, SCP-914 refinements, and more.

All gameplay modules listed above can be disabled individually inside of it.

The deeper configuration reference is available in the official Wiki.

Facility Features

SCP Unity-Inspired Building Set

The mod introduces a large collection of SCP Unity-inspired facility blocks and decorations.

The set includes walls, floors, directional markings, ventilation pieces, lights, heaters, terminals, televisions, signs, props, and themed blocks for several facility sectors.

Animated Facility Doors

SCP Additions includes multiple animated doors inspired by SCP Unity.

Keycards and Readers

SCP Additions includes six keycard clearance levels with colors based on the Anomaly Classification System:

Level 1: Unrestricted

Level 2: Restricted

Level 3: Confidential

Level 4: Secret

Level 5: Top Secret

Level 6: Cosmic Top Secret

Higher-level cards can open their own clearance level and every level below it.

Readers can be configured and copied with the Screwdriver, making it easy to build large secured facilities.

Buttons

Facility buttons provide the same door control without requiring clearance credentials.

Tesla Gates

Tesla Gates protect restricted corridors with a lethal electrical discharge.

Tesla Gate Terminal

Security Credentials grant access to a centralized terminal used to enable, disable, or place the Tesla Gate network into Emergency Override.

Decontamination Checkpoint

The Decontamination Checkpoint seals the chamber, sprays a cleaning solution mist that removes active effects, and reopens when the cycle is complete.

Passing through without proper eye protection may leave the player suffering from Eye Sore, which reduces time between automatic blinks.

Hazmat Suit

The Hazmat Suit provides sealed protection against environmental hazards, contaminated effects, and eye exposure.

Equipping and removing it takes time and requires the player to remain still. While sealed, it restricts eating and drinking, muffles external sounds, slows movement, and increases stamina consumption.

Featured SCPs

SCP-012 — A Bad Composition

(By itifamco)

SCP-012 draws nearby players toward its unfinished musical composition, progressively distorting their vision and making resistance increasingly difficult.

Design based on Event XK's SCP-012.

Prolonged exposure causes self-inflicted injuries, severe bleeding, and eventually death. SCP-079 may open its containment and manipulate nearby facility doors to trap players within its influence.

SCP-079 — Old AI

SCP-079 can interfere with connected facility doors, turning the environment itself against the player.

Design based on SCP: Containment Breach's SCP-079.

When given System Control, it can interact with doors connected to buttons or keycard readers. It may trap players in dangerous situations by closing doors in their path while they flee from a threat, or even open doors for pursuing creatures, making facility traversal more dangerous.

SCP-131-A and SCP-131-B — The Eye Pods

(By Lt Masipag)

SCP-131-A and SCP-131-B are friendly entities that may look out for you.

Design based on the SCP Foundation Wiki's SCP-131.

Besides their voices and curious behavior, the Eye Pods seem to have great instinct for threats.

SCP-173 — The Sculpture

(By Moto42)

Design based on SCP Unity's SCP-173.

SCP-173 remains completely still while observed and moves with lethal speed the moment every observer loses sight of it.

SCP-131 can keep an eye on him for you.

SCP-294 — The Coffee Machine

(By Agent Jackrabbit)

Type a request into SCP-294 and discover what the machine decides to pour.

Design based on the SCP Foundation Wiki's SCP-294.

Its drinks can produce ordinary refreshments, useful effects, dangerous substances, strange reactions, and lethal surprises. The drink library is fully expandable through the in-game Configuration Center.

SCP-330 — Take Only Two

(By DrKondraki)

A bowl of candy with one simple instruction:

"Take no more than two, please!"

The candy provides several useful effects, but ignoring the warning has severe consequences.

SCP-426 — I Am a Toaster

(By Flah)

Hello! I am a toaster, and I affect how players perceive and describe me.

SCP-572 — The Katana of Apparent Invincibility

(By DrClef)

SCP-572 gives its wielder an overwhelming sense of strength, confidence, and invincibility.

Unfortunately, the confidence it provides is much more impressive than the weapon itself.

SCP-714 — The Jaded Ring

(By Arcalane)

SCP-714 protects its wearer from dangerous mental influences, including the effects of SCP-012, but gradually drains their strength.

Design based on the SCP Foundation Wiki's SCP-714.

Keeping the ring equipped progressively slows movement, darkens vision, suppresses stamina, and may eventually leave the wearer immobilized and comatose.

SCP-902 — The Final Countdown

(By DrEverettMann)

SCP-902 is a mysterious closed box.

What is inside?

There must be something…

What is it counting down to?

SCP-914 — The Clockworks

(By Dr Gears)

SCP-914 can process items, entities, and players through five settings: Rough, Coarse, 1:1, Fine, and Very Fine.

SCP-914 has a custom interface with a draggable dial and a configurable recipe system.

Recipes can be edited or expanded through the Configuration Center, allowing custom item transformations, non-player entity transformations, weighted outputs, chances, and machine behavior. Player refinement uses dedicated outcomes for each of the five settings.

SCP-1176 — Mellified Man

(By Smapti)

SCP-1176 introduces the Mellified Man, its sarcophagus, anomalous honey, and outcomes influenced by the player's blood type.

Design based on SCP Unity's SCP-1176.

The honey may produce valuable effects or something far worse.

SCP Unity left a lasting impression on me. Even after its cancellation, its atmosphere, interface, and facility design inspired me to bring part of that experience into Minecraft.

Special thanks to SCP: Overtime for inspiring me to begin SCP Additions. Various facility block textures were also adapted from or inspired by SCP Unity-related blocks from its 1.16.5 version.

Thanks as well to the creators of the recommended companion mods for the tools and visual details that help complete the experience.
