SCP Dystopia: Redefined 2023.3.0 / Final Update (Discontinued)

SCP Dystopia: Redefined (hereafter SCPDT:R) is a robust yet very simple SCP Foundation addon. 
With SCPDT:R, you can create your desired SCP map filled with detailed mobs and functional blocks.

In survival mode, you can fight SCPs in the overworld, and spawn SCP facilities by crafting SCP documents.
There are abandoned facilities scattered around the overworld. Maybe you can find some good loots inside them.

Also, SCPDT:R does not override any vanilla features. Which means you can use SCPDT:R with other addons that overrides vanilla features (Most SCP addons do).
