This underground facility is experiencing a number of failures caused by different SCPS that have escaped from their holding cells. In this series of events, the player can take on the following roles:
Level D - prisoner of a lab rat for some reason. Their mission was to escape the facility unobserved.
Nine-tailed Fox - A mobile combat unit designed to neutralize threats and save scientists.
Scientist - Caught up in the shelter failure, in order to escape the facility alive.
SCP - an "anomaly" that tries to kill as many people as possible. Only a few SCPS are currently found in the game, but they will be increased in future updates.
Chaos splitter. - Traitor to the Foundation. The goal is to help D's escape, to get useful information.
Randomly generated facilities and character divisions make every game special and exciting!

No matter what role you play, you never know where you're heading or what's waiting behind the next door. The team that achieves all its goals is the winner.

There are many ways to fight your enemies, from using a variety of weapons and guns to blowing up entire facilities with hydrogen bombs.

In the game, we encounter the following "exceptions" :

Scp-173 - Living concrete sculpture. You can only move when you're not being watched, and you can kill people by breaking their necks.
Scp-106 - Humanoid creature that can pass through objects. It sends its prey into its pocket dimension.
Scp-079 - Self-evolving artificial intelligence. A control system that controls the entire facility.
Scp-049 - plague doctor who tries to "cure" everyone he meets.
Scp-914 - Universal converter.
