You're a guard in the SCP foundation working in site-19. You're patrolling the halls when the lights start flashing red as the breach alarms ring. All the screen notice boards around the halls display the same emergency messsge "All non combatives please seek safety in the nearest breach shelter, all combatives protect non combatives and containe any SCPs you can."

It seems like the security systems have been hacked and Every SCP on site is loose.
