SCP: Lockdown Additions - New SCPs and Horror for Minecraft
Expanding the Foundation's reach inside the cubic sandbox, SCP: Lockdown Additions - New SCPs and Horror for Minecraft serves as a companion module for the popular SCP Lockdown mod. This add-on introduces several new anomalous entities, collectible items, and utility gear designed to enhance horror maps and roleplay servers. It is a targeted package for players who want to inject the signature dread of the SCP universe into their gameplay without overhauling the entire experience.
Core Requirements and Compatibility
This is not a standalone modification. The add-on relies entirely on the parent mod, SCP Lockdown, for its core mechanics and entity behaviors. Attempting to run it without the base mod will result in errors. The developer built the add-on using MCreator, which suggests the target platform is likely Minecraft 1.12.2 or 1.16.5, both of which are common for Forge-based modpacks. Before adding it to your setup, verify that your client and server versions align. You should also check for conflicts with other mods that alter entity models or global scripts, as those can interfere with the custom animations and effects.
Installation Steps
- Install the base SCP Lockdown mod first and confirm it runs without issues.
- Download the add-on file from a trusted source.
- Place the file in the
modsfolder of your Minecraft directory. - Restart the game and check the mod list to ensure it loaded successfully.
For a streamlined process, you can download SCP: Lockdown Additions - New SCPs and Horror for Minecraft directly through the foxygame.net launcher, which simplifies the process of managing multiple mods in a single profile. This is especially useful when you want to pair it with other SCP-themed content.
Anomalies Added to the Game
The current build features four distinct SCP objects, each with a unique behavior pattern that forces players to adapt their strategy.
SCP-303 (The Doorman)
Interacting with SCP-303 via right-click triggers a debuff that applies nausea, blindness, and slowness for a full minute. This effectively simulates a paralyzing fear response, making it a strong tool for horror map creators who want to disable player movement temporarily. The texture was created by a community member known as kofoun.
SCP-2521 (●●|●●●●●|●●|●)
This information-based anomaly is implemented through a document item. When a player reads the file, the entity spawns and instantly captures the character, causing both to vanish. The game registers this as a death event, but the lore implies an abduction. This mechanic discourages players from interacting with unknown documents and adds a layer of narrative depth.
SCP-3114 (Isn't It Cold?)
SCP-3114 is an aggressive skeletal entity that actively pursues the player and attacks with a melee strike that removes bones. It is one of the most lethal mobs in the add-on. The developer plans to add a custom corpse entity that remains after the kill, but that feature is still in progress. Currently, an encounter with SCP-3114 is almost always fatal unless you have prepared defenses.
SCP-3992 (Wonder-Treasure Halloween Masks)
This set of masks transforms the player into a demon or zombie model when worn. The effect is automatic upon equipping. These items are not purely cosmetic; they can be used to create masquerade-themed events or as part of mini-game mechanics on multiplayer servers.
Additional Items and Gear
Beyond the entities, the mod includes collectible tokens and lore documents for each SCP. These can serve as rewards or decorative elements. A placeable block version of the SCP-3114 head is also available. For armor, two uniform sets are included: Security Guard and NTF. These are designed for map building and roleplay, not survival, as they lack crafting recipes and balanced stats. The textures are sourced from skins by Dr William Woods on Planet Minecraft, used with permission.
Known Issues and Development Status
The add-on is currently undergoing a full rewrite. The original files were lost when the developer upgraded to a new laptop without backing up the project. As a result, the current version may differ from future releases. Known bugs include the SCP-3992 document appearing in the wrong creative tab and lacking a proper display name. These issues are expected to be addressed in the next update. If you want to test the current mechanics, you can download SCP: Lockdown Additions - New SCPs and Horror for Minecraft for Minecraft and install it into a test world to avoid disrupting your main save.
Final Thoughts
SCP: Lockdown Additions - New SCPs and Horror for Minecraft delivers a compact but effective expansion for SCP-themed worlds. The four entities, combined with the utility items and armor, provide map makers with new tools and players with genuine tension. While the mod is in a transitional state, it is functional enough to be used in dedicated builds. If you are a fan of the Foundation lore and want to see these anomalies in block form, this add-on is worth adding to your collection.
