About this Mod

An Alpha version for 1.20.1 is avaliable!, progress updates will only be on discord!

Banner for SCP: Lockdown

SCP: Lockdown originally was a remake of the 'SCPCraft' mod created by Yu_tu. Now refreshed in 1.12 (and 1.16.5)! Lockdown's intent is to better reflect SCPs as originally defined in the SCP-Wiki.

A note about Alpha 1.16.5 Versions

Alpha versions (snapshots) are being released on an ad-hoc basis. Alphas do not reflect the final stage of the mod and is subject to be changed as development progresses. For 'Live' Updates, please join the Discord!

For versions 1.16.5, you need to use Java 16

It is critical to note that 1.12.2 worlds ARE NOT compatable with the 1.16.5 version of the mod.

This will be the only warning given and any corrupted saves as a result of trying to convert is not SCP: Lockdowns responsibility.
